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.

What is the status on this series? I read it and I think this is great.
So I am a bit sad to see it stalled for nearly one year.

With the -next development windows opening very soon, wouldn't it be a
good idea to revive this topic?


Yours sincerely,
Vincent Mailhol

yeah, it fell through the cracks after some regressions showed up in
linux-next. I'll take a look and re-submit later this week.
