9b4d5c01eb selftests: make use of GUP_TEST_FILE macro 
Commit 17de1e559c ("selftests: clarify common error when running
gup_test") had most of its hunks dropped due to a conflict with another
patch accepted into Linux around the same time that implemented the same
behavior as a subset of other changes.

However, the remaining hunk defines the GUP_TEST_FILE macro without
making use of it. This patch makes use of the macro in the two relevant
places.

Furthermore, the above mentioned commit's log message erroneously describes
the changes that were dropped from the patch.

This patch corrects the record.

When building selftests/dma:

795285ef24 selftests: Fix clang cross compilation 
Unlike GCC clang uses a single compiler image to support multiple target
architectures meaning that we can't simply rely on CROSS_COMPILE to select
the output architecture. Instead we must pass --target to the compiler to
tell it what to output, kselftest was not doing this so cross compilation
of kselftest using clang resulted in kselftest being built for the host
architecture.

More work is required to fix tests using custom rules but this gets the
bulk of things building.

 Note that this currently supports only one provider, but there seems to
 be enough interest in this functionality and we expect to see more

c6f2f3e2c8 Add partial Loongarch architecture code 
This is the majority of the loongarch architecture code, including
 the final system call interface and all core functionality.
 
 It still misses three sets of peripheral but vital patches to add
 support for other subsystems, which have yet to pass review:
 
  - The drivers/firmware/efi stub for booting from a standard UEFI
    firmware implementation. Both the original custom boot interface
    and a draft implementation of the EFI stub did not make it, so
    it is currently impossible to boot the kernel, until the
    loongarch specific portions get accepted into the UEFI subsystem
 
  - The drivers/irqchip/irq-loongson-*.c drivers are shared with the
    the MIPS port, but currently lack support for ACPI based booting,
    which will get merged through the irqchip subsystem.
 
  - Similarly, the drivers/pci/controller/pci-loongson.c needs to be
    modified for ACPI support, which will be merged through the
    PCI subsystem.
 
 While the port cannot actually be used before all the above are
 merged, having it in 5.19 helps to establish the user space ABI
 for the libc ports to build on, and to help any treewide changes
 in the mainline kernel get applied here as well. A gcc-12 based
 tool chains for build testing is now included in
 https://mirrors.edge.kernel.org/pub/tools/crosstool/.
 
 Original description from Huacai Chen at
 https://lore.kernel.org/lkml/20220603072053.35005-1-chenhuacai@loongson.cn/:
 
  "LoongArch is a new RISC ISA, which is a bit like MIPS or RISC-V.
   LoongArch includes a reduced 32-bit version (LA32R), a standard 32-bit
   version (LA32S) and a 64-bit version (LA64). LoongArch use ACPI as its
   boot protocol LoongArch-specific interrupt controllers (similar to APIC)
   are already added in the next revision of ACPI Specification (current
   revision is 6.4).
 
   This patchset is adding basic LoongArch support in mainline kernel, we
   can see a complete snapshot here:

     which will get merged through the irqchip subsystem.

   - Similarly, the drivers/pci/controller/pci-loongson.c needs to be
     modified for ACPI support, which will be merged through the PCI
     subsystem.

  While the port cannot actually be used before all the above are
  merged, having it in 5.19 helps to establish the user space ABI for
  the libc ports to build on, and to help any treewide changes in the
  mainline kernel get applied here as well.

  A gcc-12 based tool chains for build testing is now included in

    https://mirrors.edge.kernel.org/pub/tools/crosstool/"

Original description from Huacai Chen:
 "LoongArch is a new RISC ISA, which is a bit like MIPS or RISC-V.
  LoongArch includes a reduced 32-bit version (LA32R), a standard 32-bit
  version (LA32S) and a 64-bit version (LA64). LoongArch use ACPI as its
  boot protocol LoongArch-specific interrupt controllers (similar to APIC)
  are already added in the next revision of ACPI Specification (current
  revision is 6.4).

  This patchset is adding basic LoongArch support in mainline kernel, we
  can see a complete snapshot here:

62e6eb8d54 perf mem: Trace physical address for Arm SPE events 
Currently, Arm SPE events don't trace physical address, therefore, the
field 'phys_addr' is always zero in synthesized memory samples.  This
leads to perf c2c tool cannot locate the memory node for samples.

This patch enables configuration 'pa_enable' for Arm SPE events, so the
physical address packet can be traced, finally this can allow perf c2c
tool to locate properly for memory node.

151e7d7503 perf record: Support sample-read topdown metric group for hybrid platforms 
With the hardware TopDown metrics feature, the sample-read feature should
be supported for a TopDown group, e.g., sample a non-topdown event and read
a Topdown metric group. But the current perf record code errors are out.

For a TopDown metric group,the slots event must be the leader of the group,
but the leader slots event doesn't support sampling. To support sample-read
the TopDown metric group, uses the 2nd event of the group as the "leader"
for the purposes of sampling.

Only the platform with the TopDown metric feature supports sample-read the
topdown group. In commit acb65150a4 ("perf record: Support sample-read
topdown metric group"), it adds arch_topdown_sample_read() to indicate
whether the TopDown group supports sample-read, it should only work on the
non-hybrid systems, this patch extends the support for hybrid platforms.

Before:

  # ./perf record -e "{cpu_core/slots/,cpu_core/cycles/,cpu_core/topdown-retiring/}:S" -a sleep 1
  Error:
  The sys_perf_event_open() syscall returned with 22 (Invalid argument) for event (cpu_core/topdown-retiring/).
  /bin/dmesg | grep -i perf may provide additional information.

After:

  # ./perf record -e "{cpu_core/slots/,cpu_core/cycles/,cpu_core/topdown-retiring/}:S" -a sleep 1
  [ perf record: Woken up 1 times to write data ]
  [ perf record: Captured and wrote 0.238 MB perf.data (369 samples) ]

Since 10.0, ld.lld's default --rosegment -z noseparate-code layout has
such R and RX PT_LOAD program headers.

    ld.lld (default) => perf report fails to unwind `perf record
    --call-graph dwarf` recorded data
    ld.lld --no-rosegment => ok (trivial, no R PT_LOAD)
    ld.lld -z separate-code => ok but by luck: there are two PT_LOAD but
    their p_vaddr difference equals p_offset difference

    ld.bfd -z noseparate-code => ok (trivial, no R PT_LOAD)
    ld.bfd -z separate-code (default for Linux/x86) => ok but by luck:
    there are two PT_LOAD but their p_vaddr difference equals p_offset
    difference

To fix the issue, compute segbase as dso's base address plus
PT_GNU_EH_FRAME's p_vaddr. The base address is computed by iterating
over all dso-associated maps and then subtract the first PT_LOAD p_vaddr
(the minimum guaranteed by generic ABI) from the minimum address.

In libunwind, find_proc_info transitively called by unw_step is cached,
so the iteration overhead is acceptable.

e69a5c0102 perf evlist: Extend arch_evsel__must_be_in_group to support hybrid systems 
For the hybrid system, the "slots" event changes to "cpu_core/slots/", need
extend API arch_evsel__must_be_in_group() to support hybrid systems.

In the origin code, for hybrid system event "cpu_core/slots/", the output
of the API arch_evsel__must_be_in_group() is "false" (in fact,it should be
"true"). Currently only one API evsel__remove_from_group() calls it. In
evsel__remove_from_group(), it adds the second condition to check, so the
output of evsel__remove_from_group() still is correct. That's the reason
why there isn't an instant error. I'd like to fix the issue found in API
arch_evsel__must_be_in_group() in case someone else using the function in
the other place.

500a434fc5 Driver core changes for 5.19-rc1 
Here is the set of driver core changes for 5.19-rc1.
 
 Note, I'm not really happy with this pull request as-is, see below for
 details, but overall this is all good for everything but a small set of
 systems, which we have a fix for already.
 
 Lots of tiny driver core changes and cleanups happened this cycle,
 but the two major things were:
 
 	- firmware_loader reorganization and additions including the
 	  ability to have XZ compressed firmware images and the ability
 	  for userspace to initiate the firmware load when it needs to,
 	  instead of being always initiated by the kernel. FPGA devices
 	  specifically want this ability to have their firmware changed
 	  over the lifetime of the system boot, and this allows them to
 	  work without having to come up with yet-another-custom-uapi
 	  interface for loading firmware for them.
 	- physical location support added to sysfs so that devices that
 	  know this information, can tell userspace where they are
 	  located in a common way.  Some ACPI devices already support
 	  this today, and more bus types should support this in the
 	  future.
 
 Smaller changes included:
 	- driver_override api cleanups and fixes
 	- error path cleanups and fixes
 	- get_abi script fixes
 	- deferred probe timeout changes.
 
 It's that last change that I'm the most worried about.  It has been
 reported to cause boot problems for a number of systems, and I have a
 tested patch series that resolves this issue.  But I didn't get it
 merged into my tree before 5.18-final came out, so it has not gotten any
 linux-next testing.
 
 I'll send the fixup patches (there are 2) as a follow-on series to this
 pull request if you want to take them directly, _OR_ I can just revert
 the probe timeout changes and they can wait for the next -rc1 merge
 cycle.  Given that the fixes are tested, and pretty simple, I'm leaning
 toward that choice.  Sorry this all came at the end of the merge window,
 I should have resolved this all 2 weeks ago, that's my fault as it was
 in the middle of some travel for me.
 
 All have been tested in linux-next for weeks, with no reported issues
 other than the above-mentioned boot time outs.

6f9b5ed8ca Char / Misc / Other smaller driver subsystem updates for 5.19-rc1 
Here is the large set of char, misc, and other driver subsystem updates
 for 5.19-rc1.  The merge request for this has been delayed as I wanted
 to get lots of linux-next testing due to some late arrivals of changes
 for the habannalabs driver.
 
 Highlights of this merge are:
 	- habanalabs driver updates for new hardware types and fixes and
 	  other updates
 	- IIO driver tree merge which includes loads of new IIO drivers
 	  and cleanups and additions
 	- PHY driver tree merge with new drivers and small updates to
 	  existing ones
 	- interconnect driver tree merge with fixes and updates
 	- soundwire driver tree merge with some small fixes
 	- coresight driver tree merge with small fixes and updates
 	- mhi bus driver tree merge with lots of updates and new device
 	  support
 	- firmware driver updates
 	- fpga driver updates
 	- lkdtm driver updates (with a merge conflict, more on that
 	  below)
 	- extcon driver tree merge with small updates
 	- lots of other tiny driver updates and fixes and cleanups, full
 	  details in the shortlog.
 
 All of these have been in linux-next for almost 2 weeks with no reported
 problems.
 
 Note, there are 3 merge conflicts when merging this with your tree:
 	- MAINTAINERS, should be easy to resolve
 	- drivers/slimbus/qcom-ctrl.c, should be straightforward
 	  resolution
 	- drivers/misc/lkdtm/stackleak.c, not an easy resolution.  This
 	  has been noted in the linux-next tree for a while, and
 	  resolved there, here's a link to the resolution that Stephen
 	  came up with and that Kees says is correct:
 	  	https://lore.kernel.org/r/20220509185344.3fe1a354@canb.auug.org.au
 
 I will be glad to provide a merge point that contains these resolutions
 if that makes things any easier for you.

 		- fixes for devices without displayport adapters
 		- lane bonding support and improvements
 		- other minor changes based on device testing
 	- dwc3 gadget driver changes.  It seems this driver will never
 	  be finished given that the IP core is showing up in zillions
 	  of new devices and each implementation decides to do something
 	  different with it...
 	- uvc gadget driver updates as more devices start to use and
 	  rely on this hardware as well
 	- usb_maxpacket() api changes to remove an unneeded and unused
 	  parameter.
 	- usb-serial driver device id updates and small cleanups
 	- typec cleanups and fixes based on device testing
 	- device tree updates for usb properties
 	- lots of other small fixes and driver updates.
 
 All of these have been in linux-next for weeks with no reported

005f17007f bitmap: Fix return values to be unsigned 
Both nodemask and bitmap routines had mixed return values that provided
potentially signed return values that could never happen. This was
leading to the compiler getting confusing about the range of possible
return values (it was thinking things could be negative where they could
not be). In preparation for fixing nodemask, fix all the bitmap routines
that should be returning unsigned (or bool) values.

Delay accounting does not track the delay of write-protect copy.  When

Follow the pattern used by other selftests like memfd and fall back on the
standard toolchain options to build with a system installed alsa-lib if
we don't get anything from pkg-config. This reduces our build dependencies
a bit in the common case while still allowing use of pkg-config in case
there is a need for it.

3e0b8f529c net/ipv6: Expand and rename accept_unsolicited_na to accept_untracked_na 
RFC 9131 changes default behaviour of handling RX of NA messages when the
corresponding entry is absent in the neighbour cache. The current
implementation is limited to accept just unsolicited NAs. However, the
RFC is more generic where it also accepts solicited NAs. Both types
should result in adding a STALE entry for this case.

Expand accept_untracked_na behaviour to also accept solicited NAs to
be compliant with the RFC and rename the sysctl knob to
accept_untracked_na.

Merge tag 'cxl-for-5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl

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
