da995d538d s390/pci: implement reset_slot for hotplug slot 
This is done by adding a zpci_hot_reset_device() call which does a low
level reset of the PCI function without changing its higher level
function state. This way it can be used while the zPCI function is bound
to a driver and with DMA tables being controlled either through the
IOMMU or DMA APIs which is prohibited when using zpci_disable_device()
as that drop existing DMA translations.

As this reset, unlike a normal FLR, also calls zpci_clear_irq() we need
to implement arch_restore_msi_irqs() and make sure we re-enable IRQs for
the PCI function if they were previously disabled.

4fe2049770 s390/pci: refresh function handle in iomap 
The function handle of a PCI function is updated when disabling or
enabling it as well as when the function's availability changes or it
enters the error state.

Until now this only occurred either while there is no struct pci_dev
associated with the function yet or the function became unavailable.
This meant that leaving a stale function handle in the iomap either
didn't happen because there was no iomap yet or it lead to errors on PCI
access but so would the correct disabled function handle.

In the future a CLP Set PCI Function Disable/Enable cycle during PCI
device recovery may be done while the device is bound to a driver.  In
this case we must update the iomap associated with the now-stale
function handle to ensure that the resulting zPCI instruction references
an accurate function handle.

Since the function handle is accessed by the PCI accessor helpers
without locking use READ_ONCE()/WRITE_ONCE() to mark this access and
prevent compiler optimizations that would move the load/store.

With that infrastructure in place let's also properly update the
function handle in the existing cases. This makes sure that in the
future debugging of a zPCI function access through the handle will
show an up to date handle reducing the chance of confusion. Also it
makes sure we have one single place where a zPCI function handle is
updated after initialization.

53944f171a mm: remove HARDENED_USERCOPY_FALLBACK 
This has served its purpose and is no longer used.  All usercopy
violations appear to have been handled by now, any remaining instances
(or new bugs) will cause copies to be rejected.

This isn't a direct revert of commit 2d891fbc3b ("usercopy: Allow
strict enforcement of whitelists"); since usercopy_fallback is
effectively 0, the fallback handling is removed too.

This also removes the usercopy_fallback module parameter on slab_common.

952eea9b01 memblock: allow to specify flags with memblock_add_node() 
We want to specify flags when hotplugging memory.  Let's prepare to pass
flags to memblock_add_node() by adjusting all existing users.

Note that when hotplugging memory the system is already up and running
and we might have concurrent memblock users: for example, while we're
hotplugging memory, kexec_file code might search for suitable memory
regions to place kexec images.  It's important to add the memory
directly to memblock via a single call with the right flags, instead of
adding the memory first and apply flags later: otherwise, concurrent
memblock users might temporarily stumble over memblocks with wrong
flags, which will be important in a follow-up patch that introduces a
new flag to properly handle add_memory_driver_managed().

b5389086ad hugetlbfs: extend the definition of hugepages parameter to support node allocation 
We can specify the number of hugepages to allocate at boot.  But the
hugepages is balanced in all nodes at present.  In some scenarios, we
only need hugepages in one node.  For example: DPDK needs hugepages
which are in the same node as NIC.

If DPDK needs four hugepages of 1G size in node1 and system has 16 numa
nodes we must reserve 64 hugepages on the kernel cmdline.  But only four
hugepages are used.  The others should be free after boot.  If the
system memory is low(for example: 64G), it will be an impossible task.

So extend the hugepages parameter to support specifying hugepages on a
specific node.  For example add following parameter:

  hugepagesz=1G hugepages=0:1,1:3

It will allocate 1 hugepage in node0 and 3 hugepages in node1.

3ecc68349b memblock: rename memblock_free to memblock_phys_free 
Since memblock_free() operates on a physical range, make its name
reflect it and rename it to memblock_phys_free(), so it will be a
logical counterpart to memblock_phys_alloc().

The callers are updated with the below semantic patch:

    @@
    expression addr;
    expression size;
    @@
    - memblock_free(addr, size);
    + memblock_phys_free(addr, size);

c486514dd4 xen/x86: free_p2m_page: use memblock_free_ptr() to free a virtual pointer 
free_p2m_page() wrongly passes a virtual pointer to memblock_free() that
treats it as a physical address.

Call memblock_free_ptr() instead that gets a virtual address to free the

09cea61950 arm64: support page mapping percpu first chunk allocator 
Percpu embedded first chunk allocator is the firstly option, but it
could fails on ARM64, eg,

  percpu: max_distance=0x5fcfdc640000 too large for vmalloc space 0x781fefff0000
  percpu: max_distance=0x600000540000 too large for vmalloc space 0x7dffb7ff0000
  percpu: max_distance=0x5fff9adb0000 too large for vmalloc space 0x5dffb7ff0000

then we could get

  WARNING: CPU: 15 PID: 461 at vmalloc.c:3087 pcpu_get_vm_areas+0x488/0x838

and the system could not boot successfully.

Let's implement page mapping percpu first chunk allocator as a fallback
to the embedding allocator to increase the robustness of the system.

2a2e8202c7 parisc: move CPU field back into thread_info 
In commit 2214c0e772 ("parisc: Move thread_info into task struct")
PA-RISC gained support for THREAD_INFO_IN_TASK while changes were
already underway to keep the CPU field in thread_info rather than move
it into task_struct when THREAD_INFO_IN_TASK is enabled. The result is a
broken build for all PA-RISC configs that enable SMP.

So let's partially revert that commit, and get rid of the ugly hack to
get at the offset of task_struct::cpu without having to include
linux/sched.h, and put the CPU field back where it was before.

7e992711dd parisc: Don't disable interrupts in cmpxchg and futex operations 
I no longer think interrupts can be disabled in the futex and cmpxchg
operations because of COW breaks.  This not ideal but I suspect it's the
best we can do.

For the cmpxchg operations in syscall.S, we rely on the code to not
schedule off the gateway page.  For the futex, I added code to disable
preemption.

So far, I haven't seen the warnings with the attached change but the
change is only lightly tested.

If the previous context had interrupts disabled, we should better
keep them disabled. This was noticed in the unwinding code where
a copy_from_kernel_nofault() triggered a page fault, and after
the fixup by the page fault handler interrupts where suddenly
enabled.

 "These are all the driver updates for SoC specific drivers. There are a
  couple of subsystems with individual maintainers picking up their
  patches here:

   - The reset controller subsystem add support for a few new SoC
     variants to existing drivers, along with other minor improvements

   - The OP-TEE subsystem gets a driver for the ARM FF-A transport

   - The memory controller subsystem has improvements for Tegra,
     Mediatek, Renesas, Freescale and Broadcom specific drivers.

   - The tegra cpuidle driver changes get merged through this tree this
     time. There are only minor changes, but they depend on other tegra
     driver updates here.

   - The ep93xx platform finally moves to using the drivers/clk/
     subsystem, moving the code out of arch/arm in the process. This
     depends on a small sound driver change that is included here as
     well.

   - There are some minor updates for Qualcomm and Tegra specific
     firmware drivers.

  The other driver updates are mainly for drivers/soc, which contains a
  mixture of vendor specific drivers that don't really fit elsewhere:

   - Mediatek drivers gain more support for MT8192, with new support for
     hw-mutex and mmsys routing, plus support for reset lines in the
     mmsys driver.

   - Qualcomm gains a new "sleep stats" driver, and support for the
     "Generic Packet Router" in the APR driver.

   - There is a new user interface for routing the UARTS on ASpeed BMCs,
     something that apparently nobody else has needed so far.

   - More drivers can now be built as loadable modules, in particular
     for Broadcom and Samsung platforms.

   - Lots of improvements to the TI sysc driver for better
     suspend/resume support"

   - Microchip adds the SAMA5D29 SoC in the SAMA5 family, and a number
     of improvements for the recently added SAMA7 family. The LAN966 SoC
     that was added in the platform code does not have dts files yet.
     Two board files are added for the older at91sam9g20 SoC

   - Aspeed supports two additional server boards using their AST2600 as
     BMC, and improves support for qemu models

     less than their usual additions, but they also gain improvements to
     their many existing boards

   - STmicroelectronics adds their stm32mp13 SoC family along with a
     reference board

   - Renesas adds new versions of their R-Car Gen3 SoCs and many updates

     BCM53xx/BCM47xx networking SoCs and the Raspberry Pi boards

   - Mediatek improves support for the MT81xx SoCs used in Chromebooks
     as well as the MT76xx networking SoCs

   - NVIDIA adds a number of cleanups and additional support for more
     hardware on the already supported machines

   - TI K3 adds support for three new boards along with cleanups

   - Toshiba adds one board for the Visconti family

   - Xilinx adds five new ZynqMP based machines

a602285ac1 Merge branch 'per_signal_struct_coredumps-for-v5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace 
Pull per signal_struct coredumps from Eric Biederman:
 "Current coredumps are mixed up with the exit code, the signal handling
  code, and the ptrace code making coredumps much more complicated than
  necessary and difficult to follow.

  This series of changes starts with ptrace_stop and cleans it up,
  making it easier to follow what is happening in ptrace_stop. Then
  cleans up the exec interactions with coredumps. Then cleans up the
  coredump interactions with exit. Finally the coredump interactions
  with the signal handling code is cleaned up.

  The first and last changes are bug fixes for minor bugs.

  I believe the fact that vfork followed by execve can kill the process
  the called vfork if exec fails is sufficient justification to change
  the userspace visible behavior.

  In previous discussions some of these changes were organized
  differently and individually appeared to make the code base worse. As
  currently written I believe they all stand on their own as cleanups
  and bug fixes.

  Which means that even if the worst should happen and the last change
  needs to be reverted for some unimaginable reason, the code base will
  still be improved.

  If the worst does not happen there are a more cleanups that can be
  made. Signals that generate coredumps can easily become eligible for
  short circuit delivery in complete_signal. The entire rendezvous for
  generating a coredump can move into get_signal. The function
  force_sig_info_to_task be written in a way that does not modify the
  signal handling state of the target task (because coredumps are
  eligible for short circuit delivery). Many of these future cleanups
  can be done another way but nothing so cleanly as if coredumps become
  per signal_struct"

  coredump: Limit coredumps to a single thread group

c0d6586afa Merge tag 'acpi-5.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm 
Pull ACPI updates from Rafael Wysocki:
 "These update the ACPICA code in the kernel to the most recent upstream
  revision, address some issues related to the ACPI power resources
  management, simplify the enumeration of PCI devices having ACPI
  companions, add new quirks, fix assorted problems, update the
  ACPI-related information in maintainers and clean up code in several
  places.

  Specifics:

   - Update the ACPICA code in the kernel to upstream revision 20210930
     including the following changes:

        - Fix system-wide resume issue caused by evaluating control
          methods too early in the resume path (Rafael Wysocki).

        - Add support for Windows 2020 _OSI string (Mario Limonciello).

        - Add Generic Port Affinity type for SRAT (Alison Schofield).

        - Add disassembly support for the NHLT ACPI table (Bob Moore).

   - Avoid flushing caches before entering C3 type of idle states on AMD
     processors (Deepak Sharma).

   - Avoid enumerating CPUs that are not present and not online-capable
     according to the platform firmware (Mario Limonciello).

   - Add DMI-based mechanism to quirk IRQ overrides and use it for two
     platforms (Hui Wang).

   - Change the configuration of unused ACPI device objects to reflect
     the D3cold power state after enumerating devices (Rafael Wysocki).

   - Update MAINTAINERS information regarding ACPI (Rafael Wysocki).

   - Fix typo in ACPI Kconfig (Masanari Iid).

   - Use sysfs_emit() instead of snprintf() in some places (Qing Wang).

   - Make the association of ACPI device objects with PCI devices more
     straightforward and simplify the code doing that for all devices in
     general (Rafael Wysocki).

   - Use acpi_device_adr() in acpi_find_child_device() instead of
     evaluating _ADR (Rafael Wysocki).

   - Drop duplicate device IDs from PNP device IDs list (Krzysztof
     Kozlowski).

   - Allow acpi_idle_play_dead() to use C3 on AMD processors (Richard
     Gong).

   - Use ACPI_COMPANION() to simplify code in some drivers (Rafael
     Wysocki).

   - Check the states of all ACPI power resources during initialization
     to avoid dealing with power resources in unknown states (Rafael
     Wysocki).

   - Fix ACPI power resource issues related to sharing wakeup power
     resources (Rafael Wysocki).

   - Avoid registering redundant suspend_ops (Rafael Wysocki).

   - Report battery charging state as "full" if it appears to be over
     the design capacity (André Almeida).

   - Quirk GK45 mini PC to skip reading _PSR in the AC driver (Stefan
     Schaeckeler).

   - Mark apei_hest_parse() static (Christoph Hellwig).

   - Relax platform response timeout to 1 second after instructing it to
     inject an error (Shuai Xue).

   - Make the PRM code handle memory allocation and remapping failures
     more gracefully and drop some unnecessary blank lines from that
     code (Aubrey Li).

   - Fix spelling mistake in the ACPI documentation (Colin Ian King)"

Pull gfs2 mmap + page fault deadlocks fixes from Andreas Gruenbacher:
 "Functions gfs2_file_read_iter and gfs2_file_write_iter are both
  accessing the user buffer to write to or read from while holding the
  inode glock.

  In the most basic deadlock scenario, that buffer will not be resident
  and it will be mapped to the same file. Accessing the buffer will
  trigger a page fault, and gfs2 will deadlock trying to take the same
  inode glock again while trying to handle that fault.

  Fix that and similar, more complex scenarios by disabling page faults
  while accessing user buffers. To make this work, introduce a small
  amount of new infrastructure and fix some bugs that didn't trigger so
  far, with page faults enabled"

   - Switch masterclock protection from raw_spin_lock to seqcount

   - Clean up function prototypes in the page fault code and avoid
     repeated memslot lookups

   - Convey the exit reason to userspace on emulation failure

   - Configure time between NX page recovery iterations

   - Expose Predictive Store Forwarding Disable CPUID leaf

   - Allocate page tracking data structures lazily (if the i915 KVM-GT
     functionality is not compiled in)

   - Cleanups, fixes and optimizations for the shadow MMU code

  s390:

   - SIGP Fixes
