* bits/mmap.h: unify ala linux asm-generic effortsMike Frysinger2009-11-231-96/+0
| | | | | | | | | | Most ports have the same exact mman bit defines, so let's unify things like the linux kernel has with the asm-generic efforts. A few ports are left behind as they are non-trivial to merge -- the arch maintainers can tackle it if they care. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* clean up O_CLOEXEC handlingMike Frysinger2009-10-071-0/+2
| | | | | | | Drop the "#ifndef O_CLOEXEC" cruft, enable O_CLOEXEC in most fcntl.h headers, and import __ASSUME_O_CLOEXEC from glibc. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* fcntl.h: drop unused/dead O_STREAMINGMike Frysinger2009-10-071-1/+0
| | | | Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* build: Include Makefile.commonarch from common Makefile.inCarmelo Amoroso2009-07-291-2/+0
| | | | | | | | Avoid including akefile.commonarch in each Makefile.arch. Include it instead from Makefile.in just after the arch specific Makefile.arch Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>
* enable nanosecond stat support for everyoneMike Frysinger2009-07-261-12/+6
| | | | | | | | | | | | | Fill out the stat structure so that the nanosecond resolution support is always available. There is a small code size increase for a few ports (three additional assignments in xstatconv), but otherwise everything should remain the same. While we're here, punt __old_kernel_stat from the few headers that still define it as it is unused in uClibc and causes compile errors after these nanosecond changes.

* Blackfin: fix typo in byteswap.h commitMike Frysinger2009-07-231-1/+1
| | | | | | | The Blackfin port hasn't been compiling cleanly, so this typo was missed in the byteswap unification commit. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: fix incorrect attribute orderMike Frysinger2009-07-231-1/+1
| | | | | | | | | | | | | | | | | The order of attributes in a function definition matters and in a few places in the Blackfin code, it was being applied to the return type instead of the function itself. In file included from ldso/ldso/ldso.c:43: ldso/ldso/bfin/elfinterp.c: At top level: ldso/ldso/bfin/elfinterp.c:42: warning: '__visibility__' attribute ignored on non-class types In file included from ldso/ldso/bfin/elfinterp.c:341, from ldso/ldso/ldso.c:43: libc/sysdeps/linux/bfin/crtreloc.c: At top level: libc/sysdeps/linux/bfin/crtreloc.c:91: warning: 'visibility' attribute ignored on non-class types Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* create real common vfork() functionMike Frysinger2009-07-232-21/+1
| | | | | | | | | Rather than force people to always implement their own vfork(), have the default implementation be sane. For now, only the Blackfin port uses the new code. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: no need to load P5 for shared FLATJie Zhang2009-07-221-1/+0
| | | | | | | The register is already loaded for us upon entry by the kernel. Signed-off-by: Jie Zhang <jie.zhang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: fix generation of Scrt1.o for FDPICJie Zhang2009-07-221-1/+1

* Blackfin: unify FDPIC/FLAT versions of cloneMike Frysinger2009-07-221-22/+8
| | | | Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* byteswap: unify common definitionsMike Frysinger2009-07-211-76/+16
| | | | | | | | | The majority of the byteswap functions are the same across all arches, so setup a common header to provide definitions if they don't exist. This allows arches to override only the ones they actually want to implement with inline assembly. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* syscall(): create a common version based on INLINE_SYSCALL_NCS()Mike Frysinger2009-07-092-50/+1
| | | | Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* syscall: unify part 2: NCS varietyMike Frysinger2009-07-091-2/+2
| | | | | | | Declare common NCS (non-constant syscall) variants and convert the existing ports over to this. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* syscall: unify common syscall definesMike Frysinger2009-07-081-145/+0
| | | | | | | | | Unify all the common syscall defines in syscalls-common.h and scrub all the duplicated code from relevant ports. This should also make converting existing ports to INLINE_SYSCALL() much easier as they don't have to get lost in all the unrelated noise, as well as creating new ports. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* uClibc_arch_features: sync defines between portsMike Frysinger2009-07-031-0/+9
| | | | | | | Make sure each arch has the same complete list to make comparing between them easier. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
