[GIT PULL] strscpy string copy function

[Chris Metcalf <cmetcalf@ezchip.com>]

Linus,

Please pull the following changes for 4.2 from:

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

The discussion on this died down on LKML [1], so either (a) everybody loved it and
it was obviously correct, or (b) everybody lost interest.  I'm optimistically
assuming (a), but willing to hear otherwise!

Chris Metcalf (3):
       Make asm/word-at-a-time.h available on all architectures
       string: provide strscpy() and strscpy_truncate()
       tile: use global strscpy() rather than private copy
