Dear stable team (aka Greg)

Please backport

a04ac8273665 ("drm/i915/gt: Fixup tgl mocs for PTE tracking")

Note that this needs

4d8a5cfe3b13 ("drm/i915/gt: Initialize reserved and unspecified MOCS indices")

but that one has already a cc: stable, unfortunately the bugfix didn't.

Backport to where exactly?

These all seem to be in the 5.9.y tree already, do they need to go further back?

The 2nd one has cc: stable, so I worried that it might have escaped to more kernels, whereas the first one does not have cc: stable. Maybe the auto-stable picker has figured this out already (first patch does thave the right Fixes: line), I just wanted to make sure we don't end up with kernels with the broken in-between state. -Daniel
