Hello,
I noticed the following issue while attempting to build an arm64 kernel from
next-20130214, and it still seems to be present in signal/for-next and
signal/arch-arm64.
It looks to be a trivial typo.
Thanks,
Mark.

Since e6d056c7c0: "arm64: switch to generic sigaltstack", arm64 won't
build:
arch/arm64/kernel/signal.c: In function ‘sys_rt_sigreturn’:
arch/arm64/kernel/signal.c:152:2: error: incompatible type for argument 1 of
‘restore_altstack’
In file included from arch/arm64/kernel/signal.c:21:0:
include/linux/signal.h:434:5: note: expected ‘const struct stack_t *’ but
argument is of type ‘stack_t’
make[1]: *** [arch/arm64/kernel/signal.o] Error 1
make: *** [arch/arm64/kernel] Error 2
This patch fixes up the call to restore_altstack to pass the correct
type.
