v3 of https://patchwork.freedesktop.org/series/119766/

Changes from v2:

	- Do not rmw if (clr | set) covers all bits
	- Add patch to make sure the set bits are also checked on
	  wa_*_clr_set() when clr is not a superset.

Tested on DG2 with intel_reg reading 0xb158 with a busy render engine.
Now it's not losing the upper bit anymore.

Lucas De Marchi (7):
  drm/i915/gt: Move wal_get_fw_for_rmw()
  drm/i915/gt: Clear all bits from GEN12_FF_MODE2
  drm/i915/gt: Fix context workarounds with non-masked regs
  drm/i915/gt: Drop read from GEN8_L3CNTLREG in ICL workaround
  drm/i915/gt: Enable read back on XEHP_FF_MODE2
  drm/i915/gt: Remove bogus comment on IVB_FBC_RT_BASE_UPPER
  drm/i915/gt: Also check set bits in clr_set()
