I posted a change equivalent to yours earlier today:

http://lkml.kernel.org/r/1444229188-19640-1-git-send-email-cmetcalf@ezchip.com

I also did no testing, but since the rest of the PPC code is similar to the
asm-generic version, I believe the zero_bytemask() definition should be OK.

It probably should go through Linus' tree, like the previous set of patches.
I just pushed it up to the linux-tile tree for Linus to grab as:

git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile.git strscpy
