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 Chris Metcalf (1): arch/powerpc: provide zero_bytemask() for big-endian arch/powerpc/include/asm/word-at-a-time.h | 5 +++++ 1 file changed, 5 insertions(+) -- Chris Metcalf, EZChip Semiconductor http://www.ezchip.com
