Subject: [PATCH 00/40] arch: set_current_blocked() and block_sigmask()
From: Matt Fleming <matt.fleming@...el.com>
This series simplifies the architecture code for handling signals by
making use of set_current_blocked() introduced in e6fa16ab ("signal:
sigprocmask() should do retarget_shared_pending()") and
block_sigmask() introduced in commit 5e6292c0f28f ("signal: add
block_sigmask() for adding sigmask to current->blocked").
A number of architectures have bugs in this code. Using the helper
functions should avoid this problem in the future.
Note that I've only been able to compile test the following,
- alpha
- arm
- m68k
- mips
- powerpc
- s390
- sh
and that I don't have the hardware to test any of these patches.
Unlike the previous versions of this series, these patches can be
taken through the arch maintainer's trees because the requisite patch
("signal: add block_sigmask() for adding sigmask to current->blocked")
went into v3.3-rc1.
Matt Fleming (39):
alpha: Use set_current_blocked() and block_sigmask()

xtensa: Don't reimplement force_sigsegv()
xtensa: No need to reset handler if SA_ONESHOT
xtensa: Don't mask signals if we fail to setup signal stack
xtensa: Use set_current_blocked() and block_sigmask()
Oleg Nesterov (1):
avr32: use set_current_blocked() in handle_signal/sys_rt_sigreturn
