Add more docs and improve function names. I think you can keep a single versioning for the patches... it makes your life easier... with git format-patch -v X, instead of versioning each patch one by one.

Implement a way to update GGTT using MI_UPDATE_GTT command when possible for MTL as a suggested work around for HW bugs, Wa_13010847436 and Wa_14019519902. 1st patch improve pm wakeref handeling which needed as we do GGTT update with vm->mutext held and not allowed to alloc memory. 2: Fix lockdep warning related to GT wakeref vs blitter engine wakeref. v3: Rearrange patches/diffs to fix code mixups(Andi) v4: fix ce leak(Oak) v5: rebase & resend with new "Test-with" v6: move context ready status chnages to lower levels from i915_driver.c. Add more docs and improve function names.
