* Add a minor 'cas' atomic optimization on sparc.David S. Miller2013-01-232-12/+30
| | | | | | | | | * sysdeps/sparc/sparc32/sparcv9/bits/atomic.h (__arch_compare_and_exchange_val_32_acq): Use %g0 as second argument of CAS if possible. * sysdeps/sparc/sparc64/bits/atomic.h (__arch_compare_and_exchange_val_32_acq): Likewise. (__arch_compare_and_exchange_val_64_acq): Likewise.
* ulimit: remove buggy bsd implementationPino Toscano2013-01-231-91/+0
| | | | | | | | | The bsd implementation of ulimit produces wrong return values, so remove it in favour of the posix implementation. The only regression for non-Linux implementations using bsd sysdeps and not providing an own ulimit is that the __UL_GETMAXBRK case (which is non-standard) is left unimplemented (giving EINVAL).
* ulimit: include <limits.h>Pino Toscano2013-01-231-0/+1

* ulimit: move linux implementation as posixPino Toscano2013-01-231-0/+0
| | | | | The linux implementation of ulimit works correctly and has nothing specific to Linux, so move it as general posix implementation.

* PowerPC: Rename __kernel_vdso_get_tbfreq to __kernel_get_tbfreq.Anton Blanchard2013-01-184-29/+33
| | | | | | | | | | In order for the __kernel_get_tbfreq vDSO call to work the INTERNAL_VSYSCALL_NCS macro needed to be updated to prevent it from assuming an integer return type (since the timebase frequency is a 64-bit value) by specifying the type of the return type as a macro parameter. The macro then specifically declares the return value as a 'register' (or implied pair) of the denoted type. The compiler is then informed that this register (or implied pair) is to be used for the return value.

* Add HAVE_MREMAP for mremap usagePino Toscano2013-01-171-0/+2
| | | | | | | | | Introduce (only on Linux) and use a HAVE_MREMAP symbol to advertize mremap availability. Move the malloc-sysdep.h include from arena.c to malloc.c, since what is provided by malloc-sysdep.h is needed earlier in malloc.c, before the inclusion of arena.c.

* scsi/sg.h: include stddef.h for size_tMike Frysinger2013-01-151-0/+2
| | | | | | | | | This header uses size_t but doesn't include stddef.h for it. So when packages happen to include this before any header that defines size_t, they get a build failure. Reviewed-by: Carlos O'Donell <codonell@redhat.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
