The initial implementation of makecontext()
supported only 8 arguments. This change adds
support for unlimited argument processing given
a large enough stack.
Adjust the value of SOCK_CLOEXEC to match the kernel
value used for accept4. This has never worked in the
past, and all old applications are broken, therefore
we change this value to match the kernel value.
Update F_SETOWN_EX and F_GETOWN_EX. Rearrange
the file to match other targets, reducing future
diffs against other targets and making maintenance
easier.
Similar to the problems I fixed for posix_fallocate
<http://sourceware.org/ml/libc-ports/2008-12/msg00007.html> and
fallocate <http://sourceware.org/ml/libc-ports/2009-05/msg00031.html>,
MIPS64 posix_advise also needs fixes to use the correct syscall
interfaces. Although the existing n32 posix_fadvise64 is OK, getting
posix_fadvise from syscalls.list does not work correctly, as this
function is supposed to return an error code instead of storing it in
errno as the generic syscall implementations from syscalls.list do.
In the switch to NPTL the pthrad_mutex_t, pthread_cond_t,
and pthread_rwlock_t structures were made binary compatible
with the Linuxthread versions. However, their aligment when
embedded in other structures was changed. When rebuilding
libstdc++ this was detected, and the following changes return
the structures to their original Linuxthreads alignments.

* sysdeps/unix/sysv/linux/hppa/nptl/bits/pthreadtypes.h:
Use correct alignment for pthread_mutex_t, pthread_cond_t,
and pthread_rwlock_t.
Cast oldval to the same type as ret to avoid warnings when
including atomic.h.
2009-11-22 Carlos O'Donell <carlos@codesourcery.com>
* sysdeps/unix/sysv/linux/hppa/bits/atomic.h: Avoid warnings
by casting oldval to int.
Place socket.h in the correct location.

[BZ #6676]
* sysdeps/unix/sysv/linux/hppa/socket.h: Move from here...
* sysdeps/unix/sysv/linux/hppa/bits/socket.h: ... to here.
Several constants are now defined in a generic file and no longer
need to be defined in the hppa specific file.
2009-11-15 Carlos O'Donell <carlos@codesourcery.com>
* sysdeps/unix/sysv/linux/hppa/nptl/lowlevellock.h:
Remove FUTEX_WAITERS, FUTEX_OWNER_DIED, and FUTEX_TID_MASK.
[BZ #10527] Provide corrected socket constants that match the
kernel values.

[BZ #10527]
* sysdeps/unix/sysv/linux/hppa/socket.h: New file.
[BZ #10920] Use the new generic override to specify the hppa
specific libgcc_s.so.4 version number. Remove the files which
hppa no longer has to duplicate in order to accomplish
overriding libgcc_s.so version number.

[BZ #10920]
* sysdeps/hppa/libgcc_s.h: New file.

* sysdeps/unix/sysv/linux/hppa/nptl/unwind-resume.c: Remove.
Ensure that all objects in ARM EABI glibc have the proper EABI build
attributes to indicate that 8-byte stack alignment is required and
preserved. (GNU ld does not currently give errors for mixing code
requiring 8-byte alignment - such as anything built with GCC - and
code not marked as preserving it, because of the prevalence of
assembly code without proper markers to indicate that alignment is
preserved. The ARM RealView linker does give such errors.)
The bulk of the markers are accomplished by the change to sysdep.h,
but a few .S files do not include sysdep.h. In the case of
internal_accept4.S, no code is generated because EABI does not have
socketcall, but for completeness a dummy file with the right
attributes is used to override the default version in libc.
* sysdeps/arm/sysdep.h: (Tag_ABI_align8_preserved,
Tag_ABI_align8_needed): Attributes added.
* sysdeps/arm/elf/start.S: Likewise.
* sysdeps/arm/eabi/abi-note.S: New file.
* sysdeps/unix/sysv/linux/arm/eabi/internal_accept4.S: New
file.
This version of the NPTL POSIX thread ABI for hppa does
not break backwards compatibility with the the old
Linuxthreads ABI, and is therefore suitable for release
by distributions.
sysdeps/unix/sysv/linux/hppa/
* internaltypes.h: New file.

variable for env. Use expansion of CHECK_SP macro for check.
* sysdeps/mips/mips64/__longjmp.c (__Longjmp): Likewise.
sysdeps/unix/sysv/linux/internal_accept4.S expects socket.S to be
present if __NR_socketcall is defined (which it is on MIPS o32, even
though there are separate syscalls as well) and __NR_accept4 isn't.
MIPS does not have socket.S, since it uses separate syscalls, but
though the accept4 syscall should be added soon present kernel headers
do not have it. This patch creates a dummy internal_accept4.S for
MIPS o32, and an accept4.c wrapper that undefines __NR_socketcall so
that the main accept4.c falls back to the ENOSYS implementation if
__NR_accept4 isn't defined; it doesn't seem worthwhile to have a
special socketcall-based assembly implementation just for o32 on a few
kernels in the range between accept4 being available via socketcall
and the accept4 syscall being available.
