Subject: [git pull] signals, part 3
This time it's mostly helpers and conversions to them; there's a lot of
stuff remaining in the tree, but that'll either go in -rc2 (isolated bug
fixes, ideally via arch maintainers' trees) or will sit there until the
next cycle. Please, pull from
git://git.kernel.org/pub/scm/linux/kernel/git/viro/signal for-linus
Shortlog:
Al Viro (16):
HAVE_RESTORE_SIGMASK is defined on all architectures now
new helpers: {clear,test,test_and_clear}_restore_sigmask()
new helper: restore_saved_sigmask()
new helper: sigmask_to_save()
openrisc: tracehook_signal_handler() is supposed to be called on success
sh64: failure to build sigframe != signal without handler
pull clearing RESTORE_SIGMASK into block_sigmask()
don't call try_to_freeze() from do_signal()
TIF_RESTORE_SIGMASK can be set only when TIF_SIGPENDING is set
set_restore_sigmask() is never called without SIGPENDING (and never should be)
most of set_current_blocked() callers want SIGKILL/SIGSTOP removed from set
powerpc: get rid of restore_sigmask()
new helper: signal_delivered()
whack-a-mole with TIF_FREEZE
blackfin: check __get_user() return value
x86: get rid of calling do_notify_resume() when returning to kernel mode
David Howells (3):
FRV: Prevent syscall exit tracing and notify_resume at end of kernel exceptions
FRV: Shrink TIF_WORK_MASK [ver #2]
FRV: Optimise the system call exit path in entry.S [ver #2]
