2010-02-09nptl: sysdep headers re-factoringCarmelo Amoroso
This patch will re-factor and simplify sysdep headers handling for nptl branch. The reason is to use some useful macros in asm code (i.e. ENTRY()) that are available only into nptl branch because are defined in sysdep.h header under the nptl folder even if they are not related to NPTL at all (this was likely due to a bad choice done at the early stage of NPTL porting). This is a required steps for integrating into master branch some asm code available in nptl branch for sh4. The main changes are described below: nptl/sysdeps/generic/sysdep.h (moved) ---> libc/sysdeps/linux/common/sysdep.h nptl/sysdeps/arm/sysdep.h (moved) ---> libc/sysdeps/linux/arm/sysdep.h nptl/sysdeps/sh/sysdep.h ---------------------| nptl/sysdeps/unix/sh/sysdep.h ----------------| nptl/sysdeps/unix/sysv/linux/sh/sysdep.h -----| nptl/sysdeps/unix/sysv/linux/sh/sh4/sysdep.h -| |(merged) ---> libc/sysdeps/linux/sh nptl/sysdeps/unix/sysdep.h (deleted) Similarly the mips and arm sysdep.h should be merged and updated as for sh arch.

2009-12-03sh: Add a prototype for the gcc __set_fpscr internal functionCarmelo Amoroso
The sh port uses the gcc __set_fpscr internal function, but neither gcc nor glibc creates a prototype for it. This leads to a bunch of random warnings about implicit decls during the build. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>

2009-11-23bits/mmap.h: unify ala linux asm-generic effortsMike Frysinger
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>

2009-10-14Fix SH bits/kernel_types.h for new kernel headers.Joseph Myers
Recent SH kernel headers merge 32-bit and 64-bit headers, changing the include guards on asm/posix_types.h in the process; update uClibc code depending on those include guards. Signed-off-by: Joseph Myers <joseph@codesourcery.com>

2009-09-15sh/user.h: clean up conflicts from kernel user.hAndrew Stubbs
This patch makes sufficient modifications to the SH sys/user.h to be able to build and run gdbserver with Linux kernel 2.6.30. The problem is that both the kernel and library headers define the same symbols, thus making it impossible in include both headers. The patch undefines the kernel symbols in favour of the library symbols. Signed-off-by: Andrew Stubbs <ams@codesourcery.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-07-26enable nanosecond stat support for everyoneMike Frysinger
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.

2009-07-08syscall: unify common syscall definesMike Frysinger
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.
