sigaltstack infrastructure + conversion for x86, alpha and um,
COMPAT_SYSCALL_DEFINE infrastructure. Note that there are several
conflicts between "unify SS_ONSTACK/SS_DISABLE definitions" and
UAPI patches in mainline; resolution is trivial - just remove definitions
of SS_ONSTACK and SS_DISABLED from arch/*/uapi/asm/signal.h; they are
all identical and include/uapi/linux/signal.h contains the unified
variant. Please, pull from
git://git.kernel.org/pub/scm/linux/kernel/git/viro/signal for-linus
Shortlog:
Al Viro (11):
COMPAT_SYSCALL_DEFINE: infrastructure
Bury the conditionals from kernel_thread/kernel_execve series
missing user_stack_pointer() instances
new helper: current_user_stack_pointer()
unify SS_ONSTACK/SS_DISABLE definitions
new helper: restore_altstack()
new helper: compat_user_stack_pointer()
introduce generic sys_sigaltstack(), switch x86 and um to it
generic compat_sys_sigaltstack()
new helpers: __save_altstack/__compat_save_altstack, switch x86 and um to those
alpha: switch to generic sigaltstack
