2012-10-03xtensa: provide dummy gcc intrinsicsMax Filippov1-0/+17
__xtensa_libgcc_window_spill is needed for __builtin_return_address(1), but its libgcc implementation cannot be used as it makes a syscall. Atomic intrinsics are used by single staging driver. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com> Signed-off-by: Chris Zankel <chris@zankel.net>

2012-07-30ipc: add COMPAT_SHMLBA supportWill Deacon1-1/+1
If the SHMLBA definition for a native task differs from the definition for a compat task, the do_shmat() function would need to handle both. This patch introduces COMPAT_SHMLBA, which is used by the compat shmat syscall when calling the ipc code and allows architectures such as AArch64 (where the native SHMLBA is 64k but the compat (AArch32) definition is 16k) to provide the correct semantics for compat IPC system calls.

Commits d065bd810b6d ("mm: retry page fault when blocking on disk transfer") and 37b23e0525d3 ("x86,mm: make pagefault killable") introduced changes into the x86 pagefault handler for making the page fault handler retryable as well as killable.

2012-06-28Remove useless wrappers of asm-generic/rmap.hPaul Bolle1-16/+0
xtensa has a header (in its include/asm directory) that is a thin wrapper around asm-generic/rmap.h. This wrapper is useless, since that header doesn't exist. It is also unused (no file includes asm/rmap.h). openrisc generates a similar header at build time (using a generic-y entry in include/asm/Kbuild). This generated header is useless and unused too.

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).

This one ends with all sigsuspend() implementations switched to generic one (->saved_sigmask-based). With this, a bunch of assorted old buglets are fixed and most of the missing bits of NOTIFY_RESUME hookup are in place. Two more fixes sit in arm and um trees respectively, and there's a couple of broken ones that need obvious fixes - parisc and avr32 check TIF_NOTIFY_RESUME only on one of two codepaths; fixes for that will happen in the next series" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/signal: (55 commits) unicore32: if there's no handler we need to restore sigmask, syscall or no syscall xtensa: add handling of TIF_NOTIFY_RESUME microblaze: drop 'oldset' argument of do_notify_resume() microblaze: handle TIF_NOTIFY_RESUME score: add handling of NOTIFY_RESUME to do_notify_resume() m68k: add TIF_NOTIFY_RESUME and handle it. sparc: kill ancient comment in sparc_sigaction() h8300: missing checks of __get_user()/__put_user() return values frv: missing checks of __get_user()/__put_user() return values cris: missing checks of __get_user()/__put_user() return values powerpc: missing checks of __get_user()/__put_user() return values sh: missing checks of __get_user()/__put_user() return values sparc: missing checks of __get_user()/__put_user() return values avr32: struct old_sigaction is never used m32r: struct old_sigaction is never used xtensa: xtensa_sigaction doesn't exist alpha: tidy signal delivery up score: don't open-code force_sigsegv() cris: don't open-code force_sigsegv() blackfin: don't open-code force_sigsegv() ...

Pull fpu state cleanups from Ingo Molnar: "This tree streamlines further aspects of FPU handling by eliminating the prepare_to_copy() complication and moving that logic to arch_dup_task_struct(). It also fixes the FPU dumps in threaded core dumps, removes and old (and now invalid) assumption plus micro-optimizes the exit path by avoiding an FPU save for dead tasks." Fixed up trivial add-add conflict in arch/sh/kernel/process.c that came in because we now do the FPU handling in arch_dup_task_struct() rather than the legacy (and now gone) prepare_to_copy(). * 'x86-fpu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86, fpu: drop the fpu state during thread exit x86, xsave: remove thread_has_fpu() bug check in __sanitize_i387_state() coredump: ensure the fpu state is flushed for proper multi-threaded core dump fork: move the real prepare_to_copy() users to arch_dup_task_struct()
