Patch from Paul Brook The old-abi sys_syscall syscall is broken when called from Thumb mode. It assumes the syscall number is an Arm syscall number (ie. starts from __NR_OABI_SYSCALL_BASE). In thumb mode syscall numbers start from zero. The patch below fixes this by clearing the nigh bits of the syscall number instead of inverting them. Technically this means we accept some invalid syscall numbers, but I can't see how that could be a problem. The two sets of numbers far apart that unimplemented syscalls should still be rejected.
