2012-07-18C6X: clean up compiler warningMark Salter1-2/+0
commit a610d6e6: pull clearing RESTORE_SIGMASK into block_sigmask() left behind a compiler warning: arch/c6x/kernel/signal.c:252:6: warning: unused variable 'ret' This patch cleans up the warning by removing the unused variable. Signed-off-by: Mark Salter <msalter@redhat.com>
2012-06-01new helper: signal_delivered()Al Viro1-2/+1
Does block_sigmask() + tracehook_signal_handler(); called when sigframe has been successfully built. All architectures converted to it; block_sigmask() itself is gone now (merged into this one). I'm still not too happy with the signature, but that's a separate story (IMO we need a structure that would contain signal number + siginfo + k_sigaction, so that get_signal_to_deliver() would fill one, signal_delivered(), handle_signal() and probably setup...frame() - take one).

2012-06-01most of set_current_blocked() callers want SIGKILL/SIGSTOP removed from setAl Viro1-3/+0
Only 3 out of 63 do not. Renamed the current variant to __set_current_blocked(), added set_current_blocked() that will exclude unblockable signals, switched open-coded instances to it. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2012-06-01new helper: restore_saved_sigmask()Al Viro1-4/+1
first fruits of ..._restore_sigmask() helpers: now we can take boilerplate "signal didn't have a handler, clear RESTORE_SIGMASK and restore the blocked mask from ->saved_mask" into a common helper. Open-coded instances switched... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2012-04-05C6X: use set_current_blocked() and block_sigmask()Matt Fleming1-13/+3
As described in e6fa16ab9c1e ("signal: sigprocmask() should do retarget_shared_pending()") the modification of current->blocked is incorrect as we need to check whether the signal we're about to block is pending in the shared queue. Also, use the new helper function introduced in commit 5e6292c0f28f ("signal: add block_sigmask() for adding sigmask to current->blocked") which centralises the code for updating current->blocked after successfully delivering a signal and reduces the amount of duplicate code across architectures. In the past some architectures got this code wrong, so using this helper function should stop that from happening again.
