35f819d218 drm/ttm: Skip swapout if ttm object is not populated 
Swapping a ttm object which has no backend pages makes no sense.

2a269ba888 drm/ttm: fix error handling if no BO can be swapped out v4 
In case that all pre-allocated BOs are busy, just continue to populate
BOs since likely half of system memory in total is still free.

v4 (chk): fix code moved to VMWGFX as well

680dcede27 drm/ttm: switch back to static allocation limits for now 
The shrinker based approach still has some flaws. Especially that we need
temporary pages to free up the pages allocated to the driver is problematic
in a shrinker.

f07069da6b drm/ttm: move memory accounting into vmwgfx v4 
This is just another feature which is only used by VMWGFX, so move
it into the driver instead.

I've tried to add the accounting sysfs file to the kobject of the drm
minor, but I'm not 100% sure if this works as expected.

v2: fix typo in KFD and avoid 64bit divide
v3: fix init order in VMWGFX
v4: use pdev sysfs reference instead of drm
