* lstat/stat/fstat: Use 64bit version of syscall if availablemasterKhem Raj2012-02-053-13/+42
| | | | | | | | | | | | 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>

* libc_arm: avoid multiple version of __aeabi_unwind_cpp_pr dummy codeCarmelo Amoroso2012-01-271-2/+1
| | | | | | | | | 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>

* libc: do not rely upon ulimit kernel syscall.Carmelo Amoroso2011-11-231-8/+0
| | | | | | | | | | | | 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.
