alpha: wire up accept4 syscall

2011-11-01T00:30:51Z

Somehow wiring up the accept4 syscall on Alpha was missed long ago. This commit rectifies that oversight. Signed-off-by: Michael Cree Reviewed-by: Matt Turner Cc: Richard Henderson Cc: Ivan Kokshaysky Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

alpha: unbreak osf_setsysinfo(SSI_NVPAIRS, [SSIN_UACPROC, UAC_SIGBUS])

2011-08-25T23:25:33Z

The bug was accidentally found by the following program: #include #include #include static int setsysinfo(unsigned long op, void *buffer, unsigned long size, int *start, void *arg, unsigned long flag) { return syscall(__NR_osf_setsysinfo, op, buffer, size, start, arg, flag); } int main(int argc, char **argv) { short x[10]; unsigned int buf[2] = { SSIN_UACPROC, UAC_SIGBUS, }; setsysinfo(SSI_NVPAIRS, buf, 1, 0, 0, 0); int *y = (int*) (x+1); *y = 0; return 0; } The program shoud fail on SIGBUS, but didn't. The patch is a second part of userspace flag fix (commit 745dd2405e28 "Alpha: Rearrange thread info flags fixing two regressions"). Deleted outdated out-of-sync 'UAC_SHIFT' (the cause of bug) in favour of 'ALPHA_UAC_SHIFT'.

locks: move F_INPROGRESS from fl_type to fl_flags field

2011-08-19T17:25:34Z

F_INPROGRESS isn't exposed to userspace. To me it makes more sense in fl_flags.... Reviewed-by: Jeff Layton Signed-off-by: J. Bruce Fields

atomic: cleanup asm-generic atomic*.h inclusion

2011-07-26T23:49:47Z

After changing all consumers of atomics to include , we ran into some compile time errors due to this dependency chain: linux/atomic.h -> asm/atomic.h -> asm-generic/atomic-long.h where atomic-long.h could use funcs defined later in linux/atomic.h without a prototype. This patches moves the code that includes asm-generic/atomic*.h to linux/atomic.h. Archs that need need to select CONFIG_GENERIC_ATOMIC64 from now on (some of them used to include it unconditionally). Compile tested on i386 and x86_64 with allnoconfig.

asm-generic: add another generic ext2 atomic bitops

2011-07-26T23:49:46Z

The majority of architectures implement ext2 atomic bitops as test_and_{set,clear}_bit() without spinlock. This adds this type of generic implementation in ext2-atomic-setbit.h and use it wherever possible.
