33c6bd989d drm/amdkfd: debug message to count successfully migrated pages 
Not all migrate.cpages returned from migrate_vma_setup can be migrated,
for example non anonymous page, or out of device memory. So after
migrate_vma_pages returns, add debug message to count pages are
successfully migrated which has MIGRATE_PFN_VALID and
MIGRATE_PFN_MIGRATE flag set.

75fa98d6e4 drm/amdkfd: clarify the origin of cpages returned by migration functions 
cpages is only updated by migrate_vma_setup. So capture its value at
that point to clarify the significance of the number. The next patch
will add counting of actually migrated pages after migrate_vma_pages for
debug purposes.

[Why]
Immediate flip can be enabled dynamically and has higher BW requirements
when validating which voltage mode to use.

If we validate when it's not set then potentially DCFCLK will be too low
and we will underflow.

[How]
DM always requires support so always require it as part of DML input
parameters.

This can't be enabled unconditionally on older ASIC because it blocks
some expected modes so only target DCN3.1 for now.

3884d8af9b drm/i915: mark up internal objects with start_cpu_write 
While the pages can't be swapped out, they can be discarded by the shrinker.
Normally such objects are marked with __I915_MADV_PURGED, which can't be
unset, and therefore requires a new object. For kernel internal objects
this is not true, since the madv hint is reset for our special volatile
objects, such that we can re-acquire new pages, if so desired, without
needing a new object. As a result we should probably be paranoid here
and put the object back into the CPU domain when discarding the pages,
and also correctly set cache_dirty, if required.

On non-LLC platforms, force the flush-on-acquire if this is ever
swapped-in. Our async flush path is not trust worthy enough yet(and
happens in the wrong order), and with some tricks it's conceivable for
userspace to change the cache-level to I915_CACHE_NONE after the pages
are swapped-in, and since execbuf binds the object before doing the
async flush, there is a potential race window.
