Better, but there are still some errors.

powerpc:
lib/string.c: In function 'strscpy':
lib/string.c:217:4: error: implicit declaration of function 'zero_bytemask'

tile:
arch/tile/gxio/mpipe.c:46:15: error: conflicting types for 'strscpy'
include/linux/string.h:29:22: note: previous declaration of 'strscpy' was here

Missing patches:

7a5692e6e533 ("arch/powerpc: provide zero_bytemask() for big-endian")
30059d494a72 ("tile: use global strscpy() rather than private copy")
