Hi Linus,

After merging Linus' tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

lib/string.c: In function 'strscpy':
lib/string.c:209:4: error: implicit declaration of function 'zero_bytemask' [-Werror=implicit-function-declaration]
     *(unsigned long *)(dest+res) = c & zero_bytemask(data);
     ^

Caused by commit

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
