Hi Firoz,

I have one more question:

Looking at the include/uapi/asm-generic/unistd.h I see that
__NR_syscalls is not guarded by the #ifdef __KERNEL__,
why should it be guarded for xtensa?

If we remove __NR_syscall_count from the uapi header I'd
suggest dropping it completely and switching its two current
users to __NR_syscalls.
