Philip Yang 5aeaccca30 drm/amdgpu: support userptr cross VMAs case with HMM
userptr may cross two VMAs if the forked child process (not call exec
after fork) malloc buffer, then free it, and then malloc larger size
buf, kerenl will create new VMA adjacent to old VMA which was cloned
from parent process, some pages of userptr are in the first VMA, the
rest pages are in the second VMA.

HMM expects range only have one VMA, loop over all VMAs in the address
range, create multiple ranges to handle this case. See
is_mergeable_anon_vma in mm/mmap.c for details.

Philip Yang 915d3eecfa 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().

Yong Zhao 959a2091fa drm/amdgpu: Add support to change mtype for 2nd part of gart BOs on GFX9
This change prepares for a workaround in amdkfd for a GFX9 HW bug. It
requires the control stack memory of compute queues, which is allocated
from the second page of MQD gart BOs, to have mtype NC, rather than
the default UC.

Chunming Zhou 3216c6b71d drm/amdgpu: use amdgpu_bo_param for amdgpu_bo_create v2
After that, we can easily add new parameter when need.

v2:
a) rebase.
b) Initialize struct amdgpu_bo_param, future new
member could only be used in some one case, but all member
should have its own initial value.
