[ARM] 3626/1: ARM EABI: fix syscall restarting
Patch from Nicolas Pitre The RESTARTBLOCK case currently store some code on the stack to invoke sys_restart_syscall. However this is ABI dependent and there is a mismatch with the way __NR_restart_syscall gets defined when the kernel is compiled for EABI. There is also a long standing bug in the thumb case since with OABI the __NR_restart_syscall value includes __NR_SYSCALL_BASE which should not be the case for Thumb syscalls.
