Subject: [PATCH v3 0/3] Fixed-type GENMASK/BIT

ove the implementation of REG_GENMASK/REG_BIT to a more appropriate
place to be shared by i915, xe and possibly other parts of the kernel.

For now this re-defines the old macros. In future we may start using the
new macros directly, but that's a more intrusive search-and-replace.

Changes from v2:

	- Document both in commit message and code about the strict type
	  checking and give examples how it´d break with invalid params.

v1: https://lore.kernel.org/intel-xe/20230509051403.2748545-1-lucas.demarchi@intel.com/
v2: https://lore.kernel.org/intel-xe/20240124050205.3646390-1-lucas.demarchi@intel.com

Lucas De Marchi (2):
  bits: Introduce fixed-type BIT
  drm/i915: Convert REG_GENMASK* to fixed-width GENMASK_*

Yury Norov (1):
  bits: introduce fixed-type genmasks
