and userptr valid/inval list, svm_range_restore_work and
svm_range_set_attr don't access those, so do not need to take
process_info lock. This will avoid potential circular locking issue.

This change moves the amdgpu_amdkfd_pre_reset to an earlier place
in amdgpu_device_reset_sriov, presumably to address the sequence issue
that the first patch was originally meant to fix.

[Why]
IGT bypass test will set crc source as DPRX,and display DM didn`t check
connection type, it run the test on the HDMI connector ,then the kernel
will be crashed because aux->transfer is set null for HDMI connection.
This patch will skip the invalid connection test and fix kernel crash issue.

[How]
Check the connector type while setting the pipe crc source as DPRX or
auto,if the type is not DP or eDP, the crtc crc source will not be set
and report error code to IGT test,IGT will show the this subtest as no
valid crtc/connector combinations found.

[Why]
Certain USB4 docks do not seem to be able to handle disabling
DSC once it has been enabled on an MST stream. This can result
in blank displays.

[How]
As a work around, always enable DSC on docks exhibiting this issue. The
flag to indicate the use of DSC for MST streams on a USB4 dock is set
during detection of the dock and only cleared when the USB4 dock is
disconnected.

When trying to lightup two 4k60 non-DSC displays behind a branch device
that supports DSC we can't lightup both at once due to bandwidth
limitations - each requires 48 VCPI slots but we only have 63.

The workaround already exists in the code but is guarded by a CONFIG

NTFS_RW code allocates page size dependent arrays on the stack. This
results in build failures if the page size is 64k or larger.

  fs/ntfs/aops.c: In function 'ntfs_write_mst_block':
  fs/ntfs/aops.c:1311:1: error:
	the frame size of 2240 bytes is larger than 2048 bytes

Since commit f22969a6 ("powerpc/64s: Default to 64K pages for 64 bit
book3s") this affects ppc:allmodconfig builds, but other architectures
supporting page sizes of 64k or larger are also affected.

Increasing the maximum frame size for affected architectures just to
silence this error does not really help.  The frame size would have to
be set to a really large value for 256k pages.  Also, a large frame size
could potentially result in stack overruns in this code and elsewhere
and is therefore not desirable.  Make NTFS_RW dependent on page sizes
smaller than 64k instead.

When creating a new event (via a module, kprobe, eprobe, etc), the
descriptors that are created must add flags for pid filtering if an
instance has pid filtering enabled, as the flags are used at the time the
event is executed to know if pid filtering should be done or not.

The "Only trace this pid" case was added, but a cut and paste error made
that case checked twice, instead of checking the "Trace all but this pid"
case.

Pull iomap fixes from Darrick Wong:
 "A single iomap bug fix and a cleanup for 5.16-rc2.

  The bug fix changes how iomap deals with reading from an inline data
  region -- whereas the current code (incorrectly) lets the iomap read
  iter try for more bytes after reading the inline region (which zeroes
  the rest of the page!) and hopes the next iteration terminates, we
  surveyed the inlinedata implementations and realized that all
  inlinedata implementations also require that the inlinedata region end
  at EOF, so we can simply terminate the read.

  The second patch documents these assumptions in the code so that
  they're not subtle implications anymore, and cleans up some of the
  grosser parts of that function.

  Summary:

   - Fix an accounting problem where unaligned inline data reads can run
     off the end of the read iomap iterator. iomap has historically
     required that inline data mappings only exist at the end of a file,
     though this wasn't documented anywhere.

 - build fix for ZSTD enabled configs

 - fix for preempt warning

 - fix for loongson FTLB detection

 - fix for page table level selection

* tag 'mips-fixes_5.16_2' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux:
  MIPS: use 3-level pgtable for 64KB page size on MIPS_VA_BITS_48
  MIPS: loongson64: fix FTLB configuration
  MIPS: Fix using smp_processor_id() in preemptible in show_cpuinfo()
  MIPS: boot/compressed/: add __ashldi3 to target for ZSTD compression

We got issue as follows:

As ktime_set only judge 'secs' if big than KTIME_SEC_MAX, but if we pass
negative value maybe lead to overflow.
To address this issue, we must check if 'sec' is negative.
