Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/geert/linux-m68k
Pull m68k update from Geert Uytterhoeven.
This makes m68k use the generic library functions for the user-space
strn[cpy|len] functions.
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/geert/linux-m68k:
m68k: Use generic strncpy_from_user(), strlen_user(), and strnlen_user()
