[ARM] 3109/1: old ABI compat: syscall wrappers for ABI impedance matching
Patch from Nicolas Pitre
The difference between EABI and the legacy ABI may affect either
structure member alignment and/or argument register selection.
The patch has the details.
Included are wrappers for the following syscalls:
sys_stat64
sys_lstat64
sys_fstat64
sys_fcntl64
sys_epoll_ctl
sys_epoll_wait
sys_ipc
sys_semop
sys_semtimedop
sys_pread64
sys_pwrite64
sys_truncate64
sys_ftruncate64
sys_readahead
