[Intel-gfx] [PATCH v2 00/24] PPGTT dynamic page allocations

[Michel Thierry]

Addressing comments from v1.

For GEN8, it has also been extended to work in logical ring submission (lrc)
mode, as it will be the preferred mode of operation.
I also tried to update the lrc code at the same time the ppgtt refactoring
occurred, leaving only one patch that is exclusively for lrc.

This list can be seen in 3 parts:
[01-10] Include code rework for PPGTT (all GENs).
[11-14] Adds page table allocation for GEN6/GEN7
[15-24] Enables dynamic allocation in GEN8. It is enabled for both legacy
and execlist submission modes.
