Get rid of dubious casts to (void *) which causes a sparse warning.
And move largeish function from inline to the one file that uses the code,
the compiler can then decide to inline it.
Compile tested only.

Yes those functions are large enough to be de-inlined. I would like to
shrink those to functions, by replacing the switch blocks with a simple
macros, since the mask registers are contiguous.
Will repost a patch based on your patch, after a bit of testing.
Thanks,
