2012-03-26arm: disable ioperm/iopl stubsMike Frysinger
ARM always provides its own userspace funcs for ioperm/iopl. They've never had syscalls. So disable the stubs on ARM to avoid multiple definition errors. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-03-26Revert "Fix redefinition of ioperm and iopl in stubs.c and ↵Mike Frysinger
arm/{ioperm.c,iopl.c}" This reverts commit 3bcd031f97d61a8f732d865a0f4248aed2d191ab. The arm code is supposed to provide its own userspace ioperm/iopl functions. They've never had system calls for these funcs. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-03-26stubs: unified from futureBernhard Reutner-Fischer
Future branch extends stubs with ret_enosys_stub. Resolve conflicts, and use superset of future and current master. Adjust posix_fadvise* accordingly. Upon future merge, pick this master version as the final state. Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

A microblaze-specific sys/user.h is needed for (e.g.) strace, so use this version from glibc. Signed-off-by: Steve Bennett <steveb@workware.net.au> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-02-13arm: Do not use 'sed -r' to calculate IS_EABIKhem Raj
-r is not available on BSD sed so to keep compatibility avoid using it. Signed-off-by: Khem Raj <raj.khem@gmail.com>
2012-02-05lstat/stat/fstat: Use 64bit version of syscall if availableKhem Raj
This is needed for stat'ing loop devices > 255 since otherwise kernel returns EOVERFLOW becasue it needs st_rdev/st_dev to be larger than 16bits but in kernel it uses __old_kernel_stat for stat syscall which has st_rdev/st_dev as unsigned short Add a testcase Signed-off-by: Khem Raj <raj.khem@gmail.com>

2012-01-27libc_arm: avoid multiple version of __aeabi_unwind_cpp_pr dummy codeCarmelo Amoroso
Do not pollute libraries with its own implementation of __aeabi_unwind_cpp_pr1 code. Just add it to uclibc_nonshared.a archive and share it. This fixes build issue with static linking of application due to multiple symbol definition in libgcc_eh-a and libpthread.a or librt.a Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>

2011-11-23libc: do not rely upon ulimit kernel syscall.Carmelo Amoroso
On several architectures __NR_ulimit syscall number is currently defined but it is remapped onto sys_ni_syscall, while on other architectures they are not longer defined. So use {get,set}rlimit only to implement ulimit interface. It fixes LTP ulimit01 test case.
