The guest recovery sequence is buggy in Fatal Error when both
FLR & KFD reset workitems are queued at the same time. In addition,
FLR guest recovery sequence is out of order when PF/VF communication
breaks due to a GPU fatal error
As a temporary work around, perform a KFD style reset (Initiate reset
request from the guest) inside the pf2vf thread on FED.

Pull Kbuild updates from Masahiro Yamada:
- Avoid 'constexpr', which is a keyword in C23
- Allow 'dtbs_check' and 'dt_compatible_check' run independently of
'dt_binding_check'
- Fix weak references to avoid GOT entries in position-independent code
generation

All apart from AMDGPU_GEM_DOMAIN_GTT memory domains map 1:1 to TTM
placements. And the former be either AMDGPU_PL_PREEMPT or TTM_PL_TT,
depending on AMDGPU_GEM_CREATE_PREEMPTIBLE.
Simplify a few places in the code which convert the TTM placement into
a domain by checking against the current placement directly.
In the conversion AMDGPU_PL_PREEMPT either does not have to be handled
because amdgpu_mem_type_to_domain() cannot return that value anyway.

* Remove AMDGPU_PL_PREEMPT handling.

sdma_v7_0_ring_set_wptr
This commit removes a duplicate check for *is_queue_unmap in the
sdma_v7_0_ring_set_wptr function. The check at line 171 was considered
dead code because at this point in the code, we already know that
*is_queue_unmap is false due to the check at line 161.
By removing this unnecessary check, improves the readability of the
code
