Done.
Looking at it again, I wonder if it would help to use the __get_kernel_nofault()
and __get_kernel_nofault() helpers as the default in
include/asm-generic/uaccess.h.
I see it's identical to the openrisc version and would probably be the same
for some of the other architectures that have no other use for
set_fs(). That may
help to do a bulk remove of set_fs for alpha, arc, csky, h8300, hexagon, nds32,
nios2, um and extensa, leaving only ia64, sparc and sh.
