Subject: [PATCH] drm/amdkfd: Only apply heavy-weight TLB flush on
Aldebaran
It is to workaround HW bug on other Asics and based on reverting two
commits:
drm/amdkfd: Add heavy-weight TLB flush after unmapping
drm/amdkfd: Add memory sync before TLB flush
on Aldebaran as well, so this workaround
is still invalid.

Guchun
