Description

In the Linux kernel, the following vulnerability has been resolved:

drm/xe: Don't overmap identity VRAM mapping

Overmapping the identity VRAM mapping is triggering hardware bugs on
certain platforms. Use 2M pages for the last unaligned (to 1G) VRAM
chunk.

v2:
- Always use 2M pages for last chunk (Fei Yang)
- break loop when 2M pages are used
- Add assert for usable_size being 2M aligned
v3:
- Fix checkpatch
