Don't populate the read-only array flex_regs on the stack but
instead it static const. Also makes the object code a little smaller.

And will merge shortly, thanks for the patch.

Actually I couldn't merge it because you have a Author and Signed-off-by mismatch due your entry in .mailmap. Is this something you can update or send the patch from an address which matches it?
