By allowing getting reference to user fence, we can
control the lifetime outside of sync entries.

This is needed to allow vma to track the associated
user fence that was provided with bind ioctl.

v2: xe_user_fence can be kept opaque (Jani, Matt)
v3: indent fix (Matt)

Commit a0df2cc8 ("drm/xe/xe_bo_move: Enhance xe_bo_move trace")
inadvertently reverted commit 8d038f49 ("drm/xe: Fix cast on trace
variable"), breaking the build on 32bits.

As noted by Ville, there's no point in converting the pointers to u64
and add casts everywhere. In fact, it's better to just use %p and let
the address be hashed. Convert all the cases in xe_trace.h to use
pointers.

clang complains about a nonsensical test on builds with a 32-bit phys_addr_t,
which means resizing will always fail:

drivers/gpu/drm/xe/xe_mmio.c:109:23: error: result of comparison of constant 4294967296 with expression of type 'resource_size_t' (aka 'unsigned int') is always false [-Werror,-Wtautological-constant-out-of-range-compare]

      |                     ~~~~~~~~~~~~~~~ ^ ~~~~~~~~~~~~~~

Previously, BAR resize was always disallowed on 32-bit kernels, but
this apparently changed recently. Since 32-bit machines can in theory
support PAE/LPAE for large address spaces, this may end up useful,
so change the driver to shut up the warning but still work when
phys_addr_t/resource_size_t is 64 bit wide.

Mesa has been issuing a single bind operation per ioctl since xe.ko
changed to GPUVA due xe.ko bug #746. If I change Mesa to try again to
issue every single bind operation it can in the same ioctl, it hits
the MAX_BINDS assertion when running Vulkan conformance tests.

Test dEQP-VK.sparse_resources.transfer_queue.3d.rgba32i.1024_128_8
issues 960 bind operations in a single ioctl, it's the most I could
find in the conformance suite.

I don't see a reason to keep the MAX_BINDS restriction: it doesn't
seem to be preventing any specific issue. If the number is too big for
the memory allocations, then those will fail. Nothing related to
num_binds seems to be using the stack. Let's just get rid of it.

Add the flag XE_VM_BIND_FLAG_DUMPABLE to notify devcoredump that this
mapping should be dumped.

This is not hooked up, but the uapi should be ready before merging.

It's likely easier to dump the contents of the bo's at devcoredump
readout time, so it's better if the bos will stay unmodified after
a hang. The NEEDS_CPU_MAPPING flag is removed as requirement.

Pull driver core fixes from Greg KH:
 "Here are some driver core fixes, a kobject fix, and a documentation
  update for 6.8-rc5. In detail these changes are:

   - devlink fixes for reported issues with 6.8-rc1

   - topology scheduling regression fix that has been reported by many

   - kobject loosening of checks change in -rc1 is now reverted as some
     codepaths seemed to need the checks

   - documentation update for the CVE process. Has been reviewed by
     many, the last minute change to the document was to bring the .rst
     format back into the the new style rules, the contents did not
     change.

  All of these, except for the documentation update, have been in
  linux-next for over a week. The documentation update has been reviewed
  for weeks by a group of developers, and in public for a week and the
  wording has stabilized for now. If future changes are needed, we can
  do so before 6.8-final is out (or anytime after that)"

The Linux kernel project now has the ability to assign CVEs to fixed
issues, so document the process and how individual developers can get a
CVE if one is not automatically assigned for their fixes.

Fix to search a field from the structure which has anonymous union
correctly.
Since the reference `type` pointer was updated in the loop, the search
loop suddenly aborted where it hits an anonymous union. Thus it can not
find the field after the anonymous union. This avoids updating the
cursor `type` pointer in the loop.

Three fixes are included here. Two are strictly hardware-related
for the i801 and qcom-geni devices. Meanwhile, a fix from Arnd
addresses a compilation error encountered during compile test on
powerpc.

Since I have been contributing to the driver for a while and wish to help
with the review process, add myself as a reviewer.
