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

From: Lucas De Marchi
Date: Thu Feb 08 2024 - 02:45:24 EST

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