Merge branch 'asm-generic-uaccess-7' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic into asm-generic
These two functions appear to be unnecessarily different between
architectures, and the asm-generic version is a bit questionable,
even for NOMMU architectures.
Clean this up to just use the generic library version for anything
that uses the generic version today. I've expanded on the patch
descriptions a little, as suggested by Christoph Hellwig, but I
suspect a more detailed review would uncover additional problems
with the custom versions that are getting removed.
I ended up adding patches for csky and microblaze as they had the
same implementation that I removed elsewhere, these are now gone
as well.
