This arch_specific_syscall0 should be fine as well, but there is a small
chance that existing user space code refers to the __NR_arch_specific_syscall
(without trailing 0) macro, so please change 244 back to
'arch_specific_syscall'.

Not sure if we should then count from 0 or 1, i.e. whether 245 should be
arch_specific_syscall1 or arch_specific_syscall2.
