2013-04-01linux: pread/write: convert to SYSCALL_ALIGN_64BITMike Frysinger
The pread64/write64 syscalls have the 64bit register align issue for all arches. Use this new define so we can merge the powerc/xtensa versions back into the common code. SuperH is funky and also allows us to do this. We should be able to merge the mips version too, but that'll require someone to take a closer look as the current stuff doesn't look quite right.

2013-04-01libc: rename TRUNCATE64_HAS_4_ARGS to SYSCALL_ALIGN_64BITMike Frysinger
The reason truncate64 takes 4 args on some arches is that their ABI requires 64bit values to be aligned on register pair boundaries. Since this alignment affects more than just truncate64, rename the define to properly document its purpose. This also allows us to expand it to the other impacted syscalls (which will be done in a follow up commit). Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2012-10-02libc/sysdeps: add __kernel_long and __kernel_ulongChris Packham
Linux 3.4 added __kernel_long_t and __kernel_ulong_t and various exported header files were updated to use these new types. Add the definitions for __kernel_long_t and __kernel_ulong_t to the relevant kernel_types.h headers. This change was automated with the following scriptlet git grep --name-only 'typedef.*__kernel_old_dev_t' \ | xargs sed -i '/typedef.*__kernel_old_dev_t/ a\ typedef long\t\t__kernel_long_t;\ typedef unsigned long\t__kernel_ulong_t;' Whitespace in arm, avr32, hppa, sparc was then manually fixed up. Signed-off-by: Chris Packham <chris.packham@alliedtelesis.co.nz> -- Here's a cleaned up patch which should get the whitespace right. I'm a bit iffy about the sparc changes they make sense to me but it's not a platform I have access to. I can break this up per arch or per maintainer if requested. libc/sysdeps/linux/alpha/bits/kernel_types.h | 2 ++ libc/sysdeps/linux/arm/bits/kernel_types.h | 2 ++ libc/sysdeps/linux/avr32/bits/kernel_types.h | 2 ++ libc/sysdeps/linux/bfin/bits/kernel_types.h | 2 ++ libc/sysdeps/linux/c6x/bits/kernel_types.h | 2 ++ libc/sysdeps/linux/cris/bits/kernel_types.h | 2 ++ libc/sysdeps/linux/e1/bits/kernel_types.h | 2 ++ libc/sysdeps/linux/h8300/bits/kernel_types.h | 2 ++ libc/sysdeps/linux/hppa/bits/kernel_types.h | 2 ++ libc/sysdeps/linux/i386/bits/kernel_types.h | 2 ++ libc/sysdeps/linux/ia64/bits/kernel_types.h | 2 ++ libc/sysdeps/linux/m68k/bits/kernel_types.h | 2 ++ libc/sysdeps/linux/microblaze/bits/kernel_types.h | 2 ++ libc/sysdeps/linux/mips/bits/kernel_types.h | 4 ++++ libc/sysdeps/linux/nios2/bits/kernel_types.h | 2 ++ libc/sysdeps/linux/powerpc/bits/kernel_types.h | 4 ++++ libc/sysdeps/linux/sh/bits/kernel_types.h | 2 ++ libc/sysdeps/linux/sh64/bits/kernel_types.h | 2 ++ libc/sysdeps/linux/sparc/bits/kernel_types.h | 4 ++++ libc/sysdeps/linux/v850/bits/kernel_types.h | 2 ++ libc/sysdeps/linux/x86_64/bits/kernel_types.h | 2 ++ libc/sysdeps/linux/xtensa/bits/kernel_types.h | 2 ++ 22 files changed, 50 insertions(+) Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

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.

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.
