Method of getting firmware version is the same across ASICs, so remove
them from ASIC-specific files and create one in amdgpu_amdkfd.c. This new
created get_fw_version simply reads fw_version from adev-&gt;gfx than parsing
the ucode header.

This reverts commit 915d3eecfa23693bac9e54cdacf84fb4efdcc5c4.

This depends on an HMM fix which is not upstream yet.

Use HMM helper function hmm_vma_fault() to get physical pages backing
userptr and start CPU page table update track of those pages. Then use
hmm_vma_range_done() to check if those pages are updated before
amdgpu_cs_submit for gfx or before user queues are resumed for kfd.

If userptr pages are updated, for gfx, amdgpu_cs_ioctl will restart
from scratch, for kfd, restore worker is rescheduled to retry.

HMM simplify the CPU page table concurrent update check, so remove
guptasklock, mmu_invalidations, last_set_pages fields from
amdgpu_ttm_tt struct.

HMM does not pin the page (increase page ref count), so remove related
operations like release_pages(), put_page(), mark_page_dirty().

This is used for interoperability between ROCm compute and graphics
APIs. It allows importing graphics driver BOs into the ROCm SVM
address space for zero-copy GPU access.

The API is split into two steps (query and import) to allow user mode
to manage the virtual address space allocation for the imported buffer.

We don't want KFD processes evicting each other over VRAM usage.
Therefore prevent overcommitting VRAM among KFD applications with
a per-GPU limit. Also leave enough room for page tables on top
of the application memory usage.

Avoid including mmu_context.h in amdgpu_amdkfd.h since that may be
included in other header files that define traces. This leads to
conflicts due to traces defined in other headers included via
mmu_context.h.
