drm/amdgpu: replace get_user_pages with HMM mirror helpers
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().

Title:
apparent memory usage regression - not getting freed?
Status in linux package in Ubuntu:
Confirmed
Bug description:
In eoan on a 5.3 kernel, have noticed a few incidents of the system
becoming sluggish/unresponsive, which appears to be caused by low
available memory. top is reporting 13 of 16G are "used", but adding
up the memory reported by top sorted by memory usage appears like it
should be closer to 3-4G "used".
Attaching two top screenshots, one shows 3.3G used and system behaving
well, the other shows 14G used and system lagging. In both cases,
approximately the same programs are being run taking up approximately
the same amount of resident memory, so not sure where all the memory
usage is coming from.
