* most of set_current_blocked() callers want SIGKILL/SIGSTOP removed from setAl Viro2012-06-01
| | | | | | | | 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>
* MIPS: Move signal trampolines off of the stack.David Daney2010-04-12
| | | | | | | | | | | | | | | | | | | | | | This is a follow on to the vdso patch. Since all processes now have signal trampolines permanently mapped, we can use those instead of putting the trampoline on the stack and invalidating the corresponding icache across all CPUs. We also get rid of a bunch of ICACHE_REFILLS_WORKAROUND_WAR code. [Ralf: GDB 7.1 which has the necessary modifications to allow backtracing over signal frames will supposedly be released tomorrow. The old signal frame format obsoleted by this patch exists in two variations, for sane processors and for those requiring ICACHE_REFILLS_WORKAROUND_WAR. So there was never a GDB which did support backtracing over signal frames on all MIPS systems. This convinved me this series should be applied and pushed upstream as soon as possible.] Signed-off-by: David Daney <ddaney@caviumnetworks.com> To: linux-mips@linux-mips.org Patchwork: http://patchwork.linux-mips.org/patch/974/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

* [MIPS] Retry {save,restore}_fp_context if failed in atomic context.Atsushi Nemoto2007-04-20
| | | | | | | | | | | | | | | The save_fp_context()/restore_fp_context() might sleep on accessing user stack and therefore might lose FPU ownership in middle of them. If these function failed due to "in_atomic" test in do_page_fault, touch the sigcontext area in non-atomic context and retry these save/restore operation. This is a replacement of a (broken) fix which was titled "Allow CpU exception in kernel partially".

* [MIPS] Check FCSR for pending interrupts, alternative versionAtsushi Nemoto2007-03-16
| | | | | | | | | | | Commit 6d6671066a311703bca1b91645bb1e04cc983387 is incomplete and misses non-r4k CPUs. This patch reverts the commit and fixes in other way. o Do FCSR checking in caller of restore_fp_context. o Send SIGFPE if the signal handler set any FPU exception bits.

* [MIPS] signal: clean up sigframe structureFranck Bui-Huu2007-02-10
| | | | | | | | | | | This patch makes 'struct sigframe' declaration avalaible for all signals code. It allows signal32 to not have its own declaration. This patch also removes all ICACHE_REFILLS_WORKAROUND_WAR tests in structure declaration and hopefully make them more readable.

* [MIPS] signal: do not inline functions in signal-common.hFranck Bui-Huu2007-02-10
| | | | | | | | | | These functions are quite big and there are no points to make them inlined. So this patch moves the functions implementation in signal.c and make them available for others source files which need them.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
