cb5573868e Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm
Pull KVM updates from Paolo Bonzini:
 "Loongarch:

   - Add more CPUCFG mask bits

   - Improve feature detection

   - Add lazy load support for FPU and binary translation (LBT) register
     state

   - Fix return value for memory reads from and writes to in-kernel
     devices

   - Add support for detecting preemption from within a guest

   - Add KVM steal time test case to tools/selftests

  ARM:

   - Add support for FEAT_IDST, allowing ID registers that are not
     implemented to be reported as a normal trap rather than as an UNDEF
     exception

   - Add sanitisation of the VTCR_EL2 register, fixing a number of
     UXN/PXN/XN bugs in the process

   - Full handling of RESx bits, instead of only RES0, and resulting in
     SCTLR_EL2 being added to the list of sanitised registers

   - More pKVM fixes for features that are not supposed to be exposed to
     guests

   - Make sure that MTE being disabled on the pKVM host doesn't give it
     the ability to attack the hypervisor

   - Allow pKVM's host stage-2 mappings to use the Force Write Back
     version of the memory attributes by using the "pass-through'
     encoding

   - Fix trapping of ICC_DIR_EL1 on GICv5 hosts emulating GICv3 for the
     guest

   - Preliminary work for guest GICv5 support

   - A bunch of debugfs fixes, removing pointless custom iterators
     stored in guest data structures

   - A small set of FPSIMD cleanups

   - Selftest fixes addressing the incorrect alignment of page
     allocation

   - Other assorted low-impact fixes and spelling fixes

  RISC-V:

   - Fixes for issues discoverd by KVM API fuzzing in
     kvm_riscv_aia_imsic_has_attr(), kvm_riscv_aia_imsic_rw_attr(), and
     kvm_riscv_vcpu_aia_imsic_update()

   - Allow Zalasr, Zilsd and Zclsd extensions for Guest/VM

   - Transparent huge page support for hypervisor page tables

   - Adjust the number of available guest irq files based on MMIO
     register sizes found in the device tree or the ACPI tables

   - Add RISC-V specific paging modes to KVM selftests

   - Detect paging mode at runtime for selftests

  s390:

   - Performance improvement for vSIE (aka nested virtualization)

   - Completely new memory management. s390 was a special snowflake that
     enlisted help from the architecture's page table management to
     build hypervisor page tables, in particular enabling sharing the
     last level of page tables. This however was a lot of code (~3K
     lines) in order to support KVM, and also blocked several features.
     The biggest advantages is that the page size of userspace is
     completely independent of the page size used by the guest:
     userspace can mix normal pages, THPs and hugetlbfs as it sees fit,
     and in fact transparent hugepages were not possible before. It's
     also now possible to have nested guests and guests with huge pages
     running on the same host

   - Maintainership change for s390 vfio-pci

   - Small quality of life improvement for protected guests

  x86:

   - Add support for giving the guest full ownership of PMU hardware
     (contexted switched around the fastpath run loop) and allowing
     direct access to data MSRs and PMCs (restricted by the vPMU model).

     KVM still intercepts access to control registers, e.g. to enforce
     event filtering and to prevent the guest from profiling sensitive
     host state. This is more accurate, since it has no risk of
     contention and thus dropped events, and also has significantly less
     overhead.

     For more information, see the commit message for merge commit
     bf2c3138ae ("Merge tag 'kvm-x86-pmu-6.20' ...")

   - Disallow changing the virtual CPU model if L2 is active, for all
     the same reasons KVM disallows change the model after the first
     KVM_RUN

   - Fix a bug where KVM would incorrectly reject host accesses to PV
     MSRs when running with KVM_CAP_ENFORCE_PV_FEATURE_CPUID enabled,
     even if those were advertised as supported to userspace,

   - Fix a bug with protected guest state (SEV-ES/SNP and TDX) VMs,
     where KVM would attempt to read CR3 configuring an async #PF entry

   - Fail the build if EXPORT_SYMBOL_GPL or EXPORT_SYMBOL is used in KVM
     (for x86 only) to enforce usage of EXPORT_SYMBOL_FOR_KVM_INTERNAL.
     Only a few exports that are intended for external usage, and those
     are allowed explicitly

   - When checking nested events after a vCPU is unblocked, ignore
     -EBUSY instead of WARNing. Userspace can sometimes put the vCPU
     into what should be an impossible state, and spurious exit to
     userspace on -EBUSY does not really do anything to solve the issue

   - Also throw in the towel and drop the WARN on INIT/SIPI being
     blocked when vCPU is in Wait-For-SIPI, which also resulted in
     playing whack-a-mole with syzkaller stuffing architecturally
     impossible states into KVM

   - Add support for new Intel instructions that don't require anything
     beyond enumerating feature flags to userspace

   - Grab SRCU when reading PDPTRs in KVM_GET_SREGS2

   - Add WARNs to guard against modifying KVM's CPU caps outside of the
     intended setup flow, as nested VMX in particular is sensitive to
     unexpected changes in KVM's golden configuration

   - Add a quirk to allow userspace to opt-in to actually suppress EOI
     broadcasts when the suppression feature is enabled by the guest
     (currently limited to split IRQCHIP, i.e. userspace I/O APIC).
     Sadly, simply fixing KVM to honor Suppress EOI Broadcasts isn't an
     option as some userspaces have come to rely on KVM's buggy behavior
     (KVM advertises Supress EOI Broadcast irrespective of whether or
     not userspace I/O APIC supports Directed EOIs)

   - Clean up KVM's handling of marking mapped vCPU pages dirty

   - Drop a pile of *ancient* sanity checks hidden behind in KVM's
     unused ASSERT() macro, most of which could be trivially triggered
     by the guest and/or user, and all of which were useless

   - Fold "struct dest_map" into its sole user, "struct rtc_status", to
     make it more obvious what the weird parameter is used for, and to
     allow fropping these RTC shenanigans if CONFIG_KVM_IOAPIC=n

   - Bury all of ioapic.h, i8254.h and related ioctls (including
     KVM_CREATE_IRQCHIP) behind CONFIG_KVM_IOAPIC=y

   - Add a regression test for recent APICv update fixes

   - Handle "hardware APIC ISR", a.k.a. SVI, updates in
     kvm_apic_update_apicv() to consolidate the updates, and to
     co-locate SVI updates with the updates for KVM's own cache of ISR
     information

   - Drop a dead function declaration

   - Minor cleanups

  x86 (Intel):

   - Rework KVM's handling of VMCS updates while L2 is active to
     temporarily switch to vmcs01 instead of deferring the update until
     the next nested VM-Exit.

     The deferred updates approach directly contributed to several bugs,
     was proving to be a maintenance burden due to the difficulty in
     auditing the correctness of deferred updates, and was polluting
     "struct nested_vmx" with a growing pile of booleans

   - Fix an SGX bug where KVM would incorrectly try to handle EPCM page
     faults, and instead always reflect them into the guest. Since KVM
     doesn't shadow EPCM entries, EPCM violations cannot be due to KVM
     interference and can't be resolved by KVM

   - Fix a bug where KVM would register its posted interrupt wakeup
     handler even if loading kvm-intel.ko ultimately failed

   - Disallow access to vmcb12 fields that aren't fully supported,
     mostly to avoid weirdness and complexity for FRED and other
     features, where KVM wants enable VMCS shadowing for fields that
     conditionally exist

   - Print out the "bad" offsets and values if kvm-intel.ko refuses to
     load (or refuses to online a CPU) due to a VMCS config mismatch

  x86 (AMD):

   - Drop a user-triggerable WARN on nested_svm_load_cr3() failure

   - Add support for virtualizing ERAPS. Note, correct virtualization of
     ERAPS relies on an upcoming, publicly announced change in the APM
     to reduce the set of conditions where hardware (i.e. KVM) *must*
     flush the RAP

   - Ignore nSVM intercepts for instructions that are not supported
     according to L1's virtual CPU model

   - Add support for expedited writes to the fast MMIO bus, a la VMX's
     fastpath for EPT Misconfig

   - Don't set GIF when clearing EFER.SVME, as GIF exists independently
     of SVM, and allow userspace to restore nested state with GIF=0

   - Treat exit_code as an unsigned 64-bit value through all of KVM

   - Add support for fetching SNP certificates from userspace

   - Fix a bug where KVM would use vmcb02 instead of vmcb01 when
     emulating VMLOAD or VMSAVE on behalf of L2

   - Misc fixes and cleanups

  x86 selftests:

   - Add a regression test for TPR<=>CR8 synchronization and IRQ masking

   - Overhaul selftest's MMU infrastructure to genericize stage-2 MMU
     support, and extend x86's infrastructure to support EPT and NPT
     (for L2 guests)

   - Extend several nested VMX tests to also cover nested SVM

   - Add a selftest for nested VMLOAD/VMSAVE

   - Rework the nested dirty log test, originally added as a regression
     test for PML where KVM logged L2 GPAs instead of L1 GPAs, to
     improve test coverage and to hopefully make the test easier to
     understand and maintain

  guest_memfd:

   - Remove kvm_gmem_populate()'s preparation tracking and half-baked
     hugepage handling. SEV/SNP was the only user of the tracking and it
     can do it via the RMP

   - Retroactively document and enforce (for SNP) that
     KVM_SEV_SNP_LAUNCH_UPDATE and KVM_TDX_INIT_MEM_REGION require the
     source page to be 4KiB aligned, to avoid non-trivial complexity for
     something that no known VMM seems to be doing and to avoid an API
     special case for in-place conversion, which simply can't support
     unaligned sources

   - When populating guest_memfd memory, GUP the source page in common
     code and pass the refcounted page to the vendor callback, instead
     of letting vendor code do the heavy lifting. Doing so avoids a
     looming deadlock bug with in-place due an AB-BA conflict betwee
     mmap_lock and guest_memfd's filemap invalidate lock

  Generic:

   - Fix a bug where KVM would ignore the vCPU's selected address space
     when creating a vCPU-specific mapping of guest memory. Actually
     this bug could not be hit even on x86, the only architecture with
     multiple address spaces, but it's a bug nevertheless"

b52343d1cb ARM: clean up the memset64() C wrapper
The current logic to split the 64-bit argument into its 32-bit halves is
byte-order specific and a bit clunky.  Use a union instead which is
easier to read and works in all cases.

GCC still generates the same machine code.

While at it, rename the arguments of the __memset64() prototype to
actually reflect their semantics.

The alpha-specific code was newly added in commit dd5712f337 ("alpha:

Pull RISC-V updates from Paul Walmsley:

 - Add support for control flow integrity for userspace processes.

   This is based on the standard RISC-V ISA extensions Zicfiss and
   Zicfilp

 - Improve ptrace behavior regarding vector registers, and add some
   selftests

 - Optimize our strlen() assembly

 - Enable the ISO-8859-1 code page as built-in, similar to ARM64, for
   EFI volume mounting

 - Clean up some code slightly, including defining copy_user_page() as
   copy_page() rather than memcpy(), aligning us with other
   architectures; and using max3() to slightly simplify an expression
   in riscv_iommu_init_check()

Pull CXL updates from Dave Jiang:

 - Introduce cxl_memdev_attach and pave way for soft reserved handling,
   type2 accelerator enabling, and LSA 2.0 enabling. All these series
   require the endpoint driver to settle before continuing the memdev
   driver probe.

 - Address CXL port error protocol handling and reporting.

   The large patch series was split into three parts. The first two
   parts are included here with the final part coming later.

   The first part consists of a series of code refactoring to PCI AER
   sub-system that addresses CXL and also CXL RAS code to prepare for
   port error handling.

   The second part refactors the CXL code to move management of
   component registers to cxl_port objects to allow all CXL AER errors
   to be handled through the cxl_port hierarchy.

 - Provide AMD Zen5 platform address translation for CXL using ACPI
   PRMT. This includes a conventions document to explain why this is
   needed and how it's implemented.

 - Misc CXL patches of fixes, cleanups, and updates. Including CXL
   address translation for unaligned MOD3 regions.

07f440c23a arm64: mm: implement the architecture-specific clear_flush_young_ptes()
Implement the Arm64 architecture-specific clear_flush_young_ptes() to
enable batched checking of young flags and TLB flushing, improving
performance during large folio reclamation.

Performance testing:
Allocate 10G clean file-backed folios by mmap() in a memory cgroup, and
try to reclaim 8G file-backed folios via the memory.reclaim interface.  I
can observe 33% performance improvement on my Arm64 32-core server (and
10%+ improvement on my X86 machine).  Meanwhile, the hotspot
folio_check_references() dropped from approximately 35% to around 5%.

6f0e114217 arm64: mm: support batch clearing of the young flag for large folios
Currently, contpte_ptep_test_and_clear_young() and
contpte_ptep_clear_flush_young() only clear the young flag and flush TLBs
for PTEs within the contiguous range.  To support batch PTE operations for
other sized large folios in the following patches, adding a new parameter
to specify the number of PTEs that map consecutive pages of the same large
folio in a single VMA and a single page table.

While we are at it, rename the functions to maintain consistency with
other contpte_*() functions.

In order to be able to use only vma_flags_t in vm_area_desc we must adjust

Pull networking updates from Paolo Abeni:
 "Core & protocols:

   - A significant effort all around the stack to guide the compiler to
     make the right choice when inlining code, to avoid unneeded calls
     for small helper and stack canary overhead in the fast-path.

     This generates better and faster code with very small or no text
     size increases, as in many cases the call generated more code than
     the actual inlined helper.

   - Extend AccECN implementation so that is now functionally complete,
     also allow the user-space enabling it on a per network namespace
     basis.

   - Add support for memory providers with large (above 4K) rx buffer.
     Paired with hw-gro, larger rx buffer sizes reduce the number of
     buffers traversing the stack, dincreasing single stream CPU usage
     by up to ~30%.

   - Do not add HBH header to Big TCP GSO packets. This simplifies the
     RX path, the TX path and the NIC drivers, and is possible because
     user-space taps can now interpret correctly such packets without
     the HBH hint.

   - Allow IPv6 routes to be configured with a gateway address that is
     resolved out of a different interface than the one specified,
     aligning IPv6 to IPv4 behavior.

   - Multi-queue aware sch_cake. This makes it possible to scale the
     rate shaper of sch_cake across multiple CPUs, while still enforcing
     a single global rate on the interface.

   - Add support for the nbcon (new buffer console) infrastructure to
     netconsole, enabling lock-free, priority-based console operations
     that are safer in crash scenarios.

   - Improve the TCP ipv6 output path to cache the flow information,
     saving cpu cycles, reducing cache line misses and stack use.

   - Improve netfilter packet tracker to resolve clashes for most
     protocols, avoiding unneeded drops on rare occasions.

   - Add IP6IP6 tunneling acceleration to the flowtable infrastructure.

   - Reduce tcp socket size by one cache line.

   - Notify neighbour changes atomically, avoiding inconsistencies
     between the notification sequence and the actual states sequence.

   - Add vsock namespace support, allowing complete isolation of vsocks
     across different network namespaces.

   - Improve xsk generic performances with cache-alignment-oriented
     optimizations.

   - Support netconsole automatic target recovery, allowing netconsole
     to reestablish targets when underlying low-level interface comes
     back online.

  Driver API:

   - Support for switching the working mode (automatic vs manual) of a
     DPLL device via netlink.

   - Introduce PHY ports representation to expose multiple front-facing
     media ports over a single MAC.

   - Introduce "rx-polarity" and "tx-polarity" device tree properties,
     to generalize polarity inversion requirements for differential
     signaling.

   - Add helper to create, prepare and enable managed clocks.

  Device drivers:

   - Add Huawei hinic3 PF etherner driver.

   - Add DWMAC glue driver for Motorcomm YT6801 PCIe ethernet
     controller.

   - Add ethernet driver for MaxLinear MxL862xx switches

   - Remove parallel-port Ethernet driver.

   - Convert existing driver timestamp configuration reporting to
     hwtstamp_get and remove legacy ioctl().

   - Convert existing drivers to .get_rx_ring_count(), simplifing the RX
     ring count retrieval. Also remove the legacy fallback path.

   - Ethernet high-speed NICs:

KVM mediated PMU support for 6.20

Add support for mediated PMUs, where KVM gives the guest full ownership of PMU
hardware (contexted switched around the fastpath run loop) and allows direct
access to data MSRs and PMCs (restricted by the vPMU model), but intercepts
access to control registers, e.g. to enforce event filtering and to prevent the
guest from profiling sensitive host state.

To keep overall complexity reasonable, mediated PMU usage is all or nothing
for a given instance of KVM (controlled via module param).  The Mediated PMU
is disabled default, partly to maintain backwards compatilibity for existing
setup, partly because there are tradeoffs when running with a mediated PMU that
may be non-starters for some use cases, e.g. the host loses the ability to
profile guests with mediated PMUs, the fastpath run loop is also a blind spot,
entry/exit transitions are more expensive, etc.

Versus the emulated PMU, where KVM is "just another perf user", the mediated
PMU delivers more accurate profiling and monitoring (no risk of contention and
thus dropped events), with significantly less overhead (fewer exits and faster
emulation/programming of event selectors) E.g. when running Specint-2017 on
a single-socket Sapphire Rapids with 56 cores and no-SMT, and using perf from
within the guest:

  Perf command:
  a. basic-sampling: perf record -F 1000 -e 6-instructions  -a --overwrite
  b. multiplex-sampling: perf record -F 1000 -e 10-instructions -a --overwrite

  Guest performance overhead:
  ---------------------------------------------------------------------------
  | Test case          | emulated vPMU | all passthrough | passthrough with |
  |                    |               |                 | event filters    |
  ---------------------------------------------------------------------------
  | basic-sampling     |   33.62%      |    4.24%        |   6.21%          |
  ---------------------------------------------------------------------------
  | multiplex-sampling |   79.32%      |    7.34%        |   10.45%         |

KVM x86 APIC-ish changes for 6.20

 - Fix a benign bug where KVM could use the wrong memslots (ignored SMM) when
   creating a vCPU-specific mapping of guest memory.

 - Clean up KVM's handling of marking mapped vCPU pages dirty.

 - Drop a pile of *ancient* sanity checks hidden behind in KVM's unused
   ASSERT() macro, most of which could be trivially triggered by the guest
   and/or user, and all of which were useless.

 - Fold "struct dest_map" into its sole user, "struct rtc_status", to make it
   more obvious what the weird parameter is used for, and to allow burying the
   RTC shenanigans behind CONFIG_KVM_IOAPIC=y.

 - Bury all of ioapic.h and KVM_IRQCHIP_KERNEL behind CONFIG_KVM_IOAPIC=y.

 - Add a regression test for recent APICv update fixes.

 - Rework KVM's handling of VMCS updates while L2 is active to temporarily
   switch to vmcs01 instead of deferring the update until the next nested
   VM-Exit.  The deferred updates approach directly contributed to several
   bugs, was proving to be a maintenance burden due to the difficulty in
   auditing the correctness of deferred updates, and was polluting
   "struct nested_vmx" with a growing pile of booleans.

 - Handle "hardware APIC ISR", a.k.a. SVI, updates in kvm_apic_update_apicv()
   to consolidate the updates, and to co-locate SVI updates with the updates
   for KVM's own cache of ISR information.

 - Drop a dead function declaration.

KVM guest_memfd changes for 6.20

 - Remove kvm_gmem_populate()'s preparation tracking and half-baked hugepage
   handling, and instead rely on SNP (the only user of the tracking) to do its
   own tracking via the RMP.

 - Retroactively document and enforce (for SNP) that KVM_SEV_SNP_LAUNCH_UPDATE
   and KVM_TDX_INIT_MEM_REGION require the source page to be 4KiB aligned, to
   avoid non-trivial complexity for a non-existent usecase (and because
   in-place conversion simply can't support unaligned sources).

 - When populating guest_memfd memory, GUP the source page in common code and
   pass the refcounted page to the vendor callback, instead of letting vendor
   code do the heavy lifting.  Doing so avoids a looming deadlock bug with
   in-place due an AB-BA conflict betwee mmap_lock and guest_memfd's filemap
   invalidate lock.

Pull SoC devicetree updates from Arnd Bergmann:
 "There are a handful of new SoCs this time, all of these are more or
  less related to chips in a wider family:

   - SpacemiT Key Stone K3 is an 8-core risc-v chip, and the first
     widely available RVA23 implementation. Note that this is entirely
     unrelated with the similarly named Texas Instruments K3 chip family
     that follwed the TI Keystone2 SoC.

   - The Realtek Kent family of SoCs contains three chip models
     rtd1501s, rtd1861b and rtd1920s, and is related to their earlier
     Set-top-box and NAS products such as rtd1619, but is built on newer
     Arm Cortex-A78 cores.

   - The Qualcomm Milos family includes the Snapdragon 7s Gen 3 (SM7635)
     mobile phone SoC built around Armv9 Kryo cores of the Arm
     Cortex-A720 generation. This one is used in the Fairphone Gen 6

   - Qualcomm Kaanapali is a new SoC based around eight high performance
     Oryon CPU cores

   - NXP i.MX8QP and i.MX952 are both feature reduced versions of chips
     we already support, i.e. the i.MX8QM and i.MX952, with fewer CPU
     cores and I/O interfaces.

  As part of a cleanup, a number of SoC specific devicetree files got
  removed because they did not have a single board using the .dtsi files
  and they were never compile tested as a result: Samsung s3c6400, ST
  spear320s, ST stm32mp21xc/stm32mp23xc/stm32mp25xc, Renesas
  r8a779m0/r8a779m2/r8a779m4/r8a779m6/r8a779m7/r8a779m8/r8a779mb/
  r9a07g044c1/r9a07g044l1/r9a07g054l1/r9a09g047e37, and TI
  am3703/am3715. All of these could be restored easily if a new board
  gets merged.

  Broadcom/Cavium/Marvell ThunderX2 gets removed along with its only
  machine, as all remaining users are assumed to be using ACPI based
  firmware.

  A relatively small number of 43 boards get added this time, and almost
  all of them for arm64. Aside from the reference boards for the newly
  added SoCs, this includes:

   - Three server boards use 32-bit ASpeed BMCs

   - One more reference board for 32-bit Microchip LAN9668

   - 64-bit Arm single-board computers based on Amlogic s905y4, CIX
     sky1, NXP ls1028a/imx8mn/imx8mp/imx91/imx93/imx95, Qualcomm
     qcs6490/qrb2210 and Rockchip rk3568/rk3588s

   - Carrier board for SOMs using Intel agilex5, Marvell Armada 7020,
     NXP iMX8QP, Mediatek mt8370/mt8390 and rockchip rk3588

   - Two mobile phones using Snapdragon 845

   - A gaming device and a NAS box, both based on Rockchips rk356x

  On top of the newly added boards and SoCs, there is a lot of
  background activity going into cleanups, in particular towards getting
  a warning-free dtc build, and the usual work on adding support for
  more hardware on the previously added machines"

1ca28333e4 x86: keep legacy generated vdso files around in .gitignore file
Commit 93d73005bf ("x86/entry/vdso: Rename vdso_image_* to
vdso*_image") updated the vdso .gitignore file with the new filenames,
which is certainly not incorrect.

However, while adding new generated names is obviously the right thing
to do, you should *not* immediately remove the old filenames from the
.gitignore file when things move around or get renamed, because people
still have those old generated files in their build trees - and they
haven't suddenly become valid files to commit to the repository just
because they were moved or renamed.

While it's mostly just a slight visual nuisance for 'git status' that
can be fixed up with a clean build tree, it can become more serious than
that: see for example commit 04a3389b35 ("Remove stale generated
'genheaders' file").

That commit removed up a stale generated file that had been carelessly
committed by a kernel developer because it wasn't properly ignored any
more and thus showed up as a new file in their tree.

Pull VDSO updates from Thomas Gleixner:

 - Provide the missing 64-bit variant of clock_getres()

   This allows the extension of CONFIG_COMPAT_32BIT_TIME to the vDSO and
   finally the removal of 32-bit time types from the kernel and UAPI.

 - Remove the useless and broken getcpu_cache from the VDSO

   The intention was to provide a trivial way to retrieve the CPU number
   from the VDSO, but as the VDSO data is per process there is no way to
   make it work.

 - Switch get/put_unaligned() from packed struct to memcpy()

   The packed struct violates strict aliasing rules which requires to
   pass -fno-strict-aliasing to the compiler. As this are scalar values
   __builtin_memcpy() turns them into simple loads and stores

 - Use __typeof_unqual__() for __unqual_scalar_typeof()

   The get/put_unaligned() changes triggered a new sparse warning when
   __beNN types are used with get/put_unaligned() as sparse builds add a
   special 'bitwise' attribute to them which prevents sparse to evaluate
   the Generic in __unqual_scalar_typeof().

   Newer sparse versions support __typeof_unqual__() which avoids the
   problem, but requires a recent sparse install. So this adds a sanity
   check to sparse builds, which validates that sparse is available and
   capable of handling it.

 - Force inline __cvdso_clock_getres_common()

   Compilers sometimes un-inline agressively, which results in function
   call overhead and problems with automatic stack variable
   initialization.

   Interestingly enough the force inlining results in smaller code than
   the un-inlined variant produced by GCC when optimizing for size.

Pull MSI updates from Thomas Gleixner:
 "Updates for the [PCI] MSI subsystem:

   - Add interrupt redirection infrastructure

     Some PCI controllers use a single demultiplexing interrupt for the
     MSI interrupts of subordinate devices.

     This prevents setting the interrupt affinity of device interrupts,
     which causes device interrupts to be delivered to a single CPU.
     That obviously is counterproductive for multi-queue devices and
     interrupt balancing.

     To work around this limitation the new infrastructure installs a
     dummy irq_set_affinity() callback which captures the affinity mask
     and picks a redirection target CPU out of the mask.

     When the PCI controller demultiplexes the interrupts it invokes a
     new handling function in the core, which either runs the interrupt
     handler in the context of the target CPU or delegates it to
     irq_work on the target CPU.

   - Utilize the interrupt redirection mechanism in the PCI DWC host
     controller driver.

     This allows affinity control for the subordinate device MSI
     interrupts instead of being randomly executed on the CPU which runs
     the demultiplex handler.

   - Replace the binary 64-bit MSI flag with a DMA mask

     Some PCI devices have PCI_MSI_FLAGS_64BIT in the MSI capability,
     but implement less than 64 address bits. This breaks on platforms
     where such a device is assigned an MSI address higher than what's
     supported.

     With the binary 64-bit flag there is no other choice than disabling
     64-bit MSI support which leaves the device disfunctional.

     By using a DMA mask the address limit of a device can be described
     correctly which provides support for the above scenario.

   - Make use of the DMA mask based address limit in the hda/intel and
     radeon drivers to enable them on affected platforms

   - The usual small cleanups and improvements"

Pull irq core updates from Thomas Gleixner:
 "Updates for the interrupt core subsystem:

   - Remove the interrupt timing infrastructure

     This was added seven years ago to be used for power management
     purposes, but that integration never happened.

   - Clean up the remaining setup_percpu_irq() users

     The memory allocator is available when interrupts can be requested
     so there is not need for static irq_action. Move the remaining
     users to request_percpu_irq() and delete the historical cruft.

   - Warn when interrupt flag inconsistencies are detected in
     request*_irq().

     Inconsistent flags can lead to hard to diagnose malfunction. The
     fallout of this new warning has been addressed in next and the
     fixes are coming in via the maintainer trees and the tip
     irq/cleanup pull requests.

   - Invoke affinity notifier when CPU hotplug breaks affinity

     Otherwise the code using the notifier misses the affinity change
     and operates on stale information.

   - The usual cleanups and improvements"
