vdpa: multiple address spaces support
This patches introduces the multiple address spaces support for vDPA device. This idea is to identify a specific address space via an dedicated identifier - ASID. During vDPA device allocation, vDPA device driver needs to report the number of address spaces supported by the device then the DMA mapping ops of the vDPA device needs to be extended to support ASID. This helps to isolate the environments for the virtqueue that will not be assigned directly. E.g in the case of virtio-net, the control virtqueue will not be assigned directly to guest. As a start, simply claim 1 virtqueue groups and 1 address spaces for all vDPA devices. And vhost-vDPA will simply reject the device with more than 1 virtqueue groups or address spaces.

vdpa: Add support for querying vendor statistics
Allows to read vendor statistics of a vdpa device. The specific
statistics data are received from the upstream driver in the form of an
(attribute name, attribute value) pairs.
An example of statistics for mlx5_vdpa device are:
received_desc - number of descriptors received by the virtqueue
completed_desc - number of descriptors completed by the virtqueue
A descriptor using indirect buffers is still counted as 1. In addition,
N chained descriptors are counted correctly N times as one would expect.
A new callback was added to vdpa_config_ops which provides the means for
the vdpa driver to return statistics results.
The interface allows for reading all the supported virtqueues, including
the control virtqueue if it exists.
Below are some examples taken from mlx5_vdpa which are introduced in the
following patch:
1. Read statistics for the virtqueue at index 1
$ vdpa dev vstats show vdpa-a qidx 1
vdpa-a:
queue_type tx queue_index 1 received_desc 3844836 completed_desc 3844836
2. Read statistics for the virtqueue at index 32
$ vdpa dev vstats show vdpa-a qidx 32
vdpa-a:
queue_type control_vq queue_index 32 received_desc 62 completed_desc 62
3. Read statisitics for the virtqueue at index 0 with json output
$ vdpa -j dev vstats show vdpa-a qidx 0
{"vstats":{"vdpa-a":{
"queue_type":"rx","queue_index":0,"name":"received_desc","value":417776,\
"name":"completed_desc","value":417548}}}
4. Read statistics for the virtqueue at index 0 with preety json output
$ vdpa -jp dev vstats show vdpa-a qidx 0
{
"vstats": {
"vdpa-a": {
"queue_type": "rx",
"queue_index": 0,
"name": "received_desc",
"value": 417776,
"name": "completed_desc",
"value": 417548
}
}

drm: fix EDID struct for old ARM OABI format
When building the kernel for arm with the "-mabi=apcs-gnu" option, gcc
will force alignment of all structures and unions to a word boundary
(see also STRUCTURE_SIZE_BOUNDARY and the "-mstructure-size-boundary=XX"
option if you're a gcc person), even when the members of said structures
do not want or need said alignment.
This completely messes up the structure alignment of 'struct edid' on
those targets, because even though all the embedded structures are
marked with "__attribute__((packed))", the unions that contain them are
not.
This was exposed by commit

Pull cxl updates from Dan Williams:
"Compute Express Link (CXL) updates for this cycle.
The highlight is new driver-core infrastructure and CXL subsystem
changes for allowing lockdep to validate device_lock() usage. Thanks
to PeterZ for setting me straight on the current capabilities of the
lockdep API, and Greg acked it as well.
On the CXL ACPI side this update adds support for CXL _OSC so that
platform firmware knows that it is safe to still grant Linux native
control of PCIe hotplug and error handling in the presence of CXL
devices. A circular dependency problem was discovered between suspend
and CXL memory for cases where the suspend image might be stored in
CXL memory where that image also contains the PCI register state to
restore to re-enable the device. Disable suspend for now until an
architecture is defined to clarify that conflict.
Lastly a collection of reworks, fixes, and cleanups to the CXL
subsystem where support for snooping mailbox commands and properly
handling the "mem_enable" flow are the highlights.
Summary:
- Add driver-core infrastructure for lockdep validation of
device_lock(), and fixup a deadlock report that was previously
hidden behind the 'lockdep no validate' policy.
- Add CXL _OSC support for claiming native control of CXL hotplug and
error handling.
- Disable suspend in the presence of CXL memory unless and until a
protocol is identified for restoring PCI device context from memory
hosted on CXL PCI devices.
- Add support for snooping CXL mailbox commands to protect against
inopportune changes, like set-partition with the 'immediate' flag
set.
- Rework how the driver detects legacy CXL 1.1 configurations (CXL
DVSEC / 'mem_enable') before enabling new CXL 2.0 decode
configurations (CXL HDM Capability).
- Miscellaneous cleanups and fixes from -next exposure"

Pull clk updates from Stephen Boyd:
"Mainly driver updates this time around.
There's a single patch to the core clk framework that simplifies a
runtime PM call. Otherwise the majority of the diff falls to a few SoC
drivers: Qualcomm, STM32 and MediaTek. Those SoCs gain some new
hardware support and what comes along with that is quite a few lines
of data and some clk_ops code.
Beyond the new hardware support we have the usual pile of driver
updates that add missing clks on already supported SoCs or fix up
problems like bad clk tree descriptions. It's nice to see that more
drivers are moving to clk_hw based APIs too.
New Drivers:

- Convert ux500 to clk_hw
- Move MediaTek driver to clk_hw provider APIs
- Use i2c driver probe_new to avoid id scans

- Mark hclk_vo critical on Rockchip rk3568
- Use pm_runtime_resume_and_get to fix pm_runtime_get_sync() usage
- Various cleanups like memory allocation error checks and plugged
leaks
- Allwinner H6 RTC clock support
- Allwinner H616 32 kHz clock support
- Add the Universal Flash Storage clock on Renesas R-Car S4-8

I/O Bus, RSPI, TSU (thermal), and ADC clocks and resets on Renesas
RZ/G2UL
- Add display clock support on Renesas RZ/G2L
- Add RPC (QSPI/HyperFlash) clocks on Renesas R-Car E3 and D3
- Add 27 MHz phy PLL ref clock on i.MX
- Add mcore_booted module parameter to tell kernel M core has already

mm: fix is_pinnable_page against a cma page
Pages in the CMA area could have MIGRATE_ISOLATE as well as MIGRATE_CMA so
the current is_pinnable_page() could miss CMA pages which have
MIGRATE_ISOLATE. It ends up pinning CMA pages as longterm for the
pin_user_pages() API so CMA allocations keep failing until the pin is
released.
CPU 0 CPU 1 - Task B
cma_alloc
alloc_contig_range
pin_user_pages_fast(FOLL_LONGTERM)
change pageblock as MIGRATE_ISOLATE
internal_get_user_pages_fast
lockless_pages_from_mm
gup_pte_range
try_grab_folio
is_pinnable_page
return true;
So, pinned the page successfully.
page migration failure with pinned page
..
.. After 30 sec
unpin_user_page(page)
CMA allocation succeeded after 30 sec.
The CMA allocation path protects the migration type change race using
zone->lock but what GUP path need to know is just whether the page is on
CMA area or not rather than exact migration type. Thus, we don't need
zone->lock but just checks migration type in either of (MIGRATE_ISOLATE
and MIGRATE_CMA).
Adding the MIGRATE_ISOLATE check in is_pinnable_page could cause rejecting
of pinning pages on MIGRATE_ISOLATE pageblocks even though it's neither
CMA nor movable zone if the page is temporarily unmovable. However, such
a migration failure by unexpected temporal refcount holding is general
issue, not only come from MIGRATE_ISOLATE and the MIGRATE_ISOLATE is also
transient state like other temporal elevated refcount problem.

mm/swapfile: unuse_pte can map random data if swap read fails
Patch series "A few fixup patches for mm", v4. This series contains a few patches to avoid mapping random data if swap read fails and fix lost swap bits in unuse_pte. Also we free hwpoison and swapin error entry in madvise_free_pte_range and so on. More details can be found in the respective changelogs. This patch (of 5): There is a bug in unuse_pte(): when swap page happens to be unreadable, page filled with random data is mapped into user address space. In case of error, a special swap entry indicating swap read fails is set to the page table. So the swapcache page can be freed and the user won't end up with a permanently mounted swap because a sector is bad. And if the page is accessed later, the user process will be killed so that corrupted data is never consumed. On the other hand, if the page is never accessed, the user won't even notice it.

kexec_file: drop weak attribute from arch_kexec_apply_relocations[_add]
Since commit d1bcae833b32f1 ("ELF: Don't generate unused section
symbols") [1], binutils (v2.36+) started dropping section symbols that
it thought were unused. This isn't an issue in general, but with
kexec_file.c, gcc is placing kexec_arch_apply_relocations[_add] into a
separate .text.unlikely section and the section symbol ".text.unlikely"
is being dropped. Due to this, recordmcount is unable to find a non-weak
symbol in .text.unlikely to generate a relocation record against.
Address this by dropping the weak attribute from these functions.
Instead, follow the existing pattern of having architectures #define the
name of the function they want to override in their headers.

Pull nfsd updates from Chuck Lever: "We introduce 'courteous server' in this release. Previously NFSD would purge open and lock state for an unresponsive client after one lease period (typically 90 seconds). Now, after one lease period, another client can open and lock those files and the unresponsive client's lease is purged; otherwise if the unresponsive client's open and lock state is uncontended, the server retains that open and lock state for up to 24 hours, allowing the client's workload to resume after a lengthy network partition. A longstanding issue with NFSv4 file creation is also addressed. Previously a file creation can fail internally, returning an error to the client, but leave the newly created file in place as an artifact. The file creation code path has been reorganized so that internal failures and race conditions are less likely to result in an unwanted file creation. A fault injector has been added to help exercise paths that are run during kernel metadata cache invalidation. These caches contain information maintained by user space about exported filesystems. Many of our test workloads do not trigger cache invalidation.

Pull modules updates from Luis Chamberlain:
- It was time to tidy up kernel/module.c and one way of starting with
that effort was to split it up into files. At my request Aaron Tomlin
spearheaded that effort with the goal to not introduce any functional
at all during that endeavour. The penalty for the split is +1322
bytes total, +112 bytes in data, +1210 bytes in text while bss is
unchanged. One of the benefits of this other than helping make the
code easier to read and review is summoning more help on review for
changes with livepatching so kernel/module/livepatch.c is now pegged
as maintained by the live patching folks.
The before and after with just the move on a defconfig on x86-64:
$ size kernel/module.o
text data bss dec hex filename
38434 4540 104 43078 a846 kernel/module.o
$ size -t kernel/module/*.o

- Aaron added module unload taint tracking (MODULE_UNLOAD_TAINT_TRACKING),
to enable tracking unloaded modules which did taint the kernel.
- Christophe Leroy added CONFIG_ARCH_WANTS_MODULES_DATA_IN_VMALLOC
which lets architectures to request having modules data in vmalloc
area instead of module area. There are three reasons why an
architecture might want this:
a) On some architectures (like book3s/32) it is not possible to
protect against execution on a page basis. The exec stuff can be
mapped by different arch segment sizes (on book3s/32 that is 256M
segments). By default the module area is in an Exec segment while
vmalloc area is in a NoExec segment. Using vmalloc lets you muck
with module data as NoExec on those architectures whereas before
you could not.
b) By pushing more module data to vmalloc you also increase the
probability of module text to remain within a closer distance
from kernel core text and this reduces trampolines, this has been
reported on arm first and powerpc folks are following that lead.
c) Free'ing module_alloc() (Exec by default) area leaves this
exposed as Exec by default, some architectures have some security
enhancements to set this as NoExec on free, and splitting module
data with text let's future generic special allocators be added
to the kernel without having developers try to grok the tribal
knowledge per arch. Work like Rick Edgecombe's permission vmalloc
interface [0] becomes easier to address over time.

Pull MM updates from Andrew Morton:
"Almost all of MM here. A few things are still getting finished off,
reviewed, etc.
- Yang Shi has improved the behaviour of khugepaged collapsing of
readonly file-backed transparent hugepages.
- Johannes Weiner has arranged for zswap memory use to be tracked and
managed on a per-cgroup basis.
- Munchun Song adds a /proc knob ("hugetlb_optimize_vmemmap") for
runtime enablement of the recent huge page vmemmap optimization
feature.
- Baolin Wang contributes a series to fix some issues around hugetlb
pagetable invalidation.
- Zhenwei Pi has fixed some interactions between hwpoisoned pages and
virtualization.
- Tong Tiangen has enabled the use of the presently x86-only
page_table_check debugging feature on arm64 and riscv.
- David Vernet has done some fixup work on the memcg selftests.
- Peter Xu has taught userfaultfd to handle write protection faults
against shmem- and hugetlbfs-backed files.
- More DAMON development from SeongJae Park - adding online tuning of
the feature and support for monitoring of fixed virtual address
ranges. Also easier discovery of which monitoring operations are
available.
- Nadav Amit has done some optimization of TLB flushing during
mprotect().
- Neil Brown continues to labor away at improving our swap-over-NFS
support.
- David Hildenbrand has some fixes to anon page COWing versus
get_user_pages().
- Peng Liu fixed some errors in the core hugetlb code.
- Joao Martins has reduced the amount of memory consumed by
device-dax's compound devmaps.

Merge tag 'asm-generic-5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic
Pull asm-generic updates from Arnd Bergmann:
"The asm-generic tree contains three separate changes for linux-5.19:
- The h8300 architecture is retired after it has been effectively
unmaintained for a number of years. This is the last architecture
we supported that has no MMU implementation, but there are still a
few architectures (arm, m68k, riscv, sh and xtensa) that support
CPUs with and without an MMU.
- A series to add a generic ticket spinlock that can be shared by
most architectures with a working cmpxchg or ll/sc type atomic,
including the conversion of riscv, csky and openrisc. This series
is also a prerequisite for the loongarch64 architecture port that
will come as a separate pull request.
- A cleanup of some exported uapi header files to ensure they can be
included from user space without relying on other kernel headers"
