NR_syscalls macro holds the number of system call exist in SH arch-
itecture. One of the patch in this patch series has a script which
will generate a uapi header based on syscall.tbl file. The syscall.tbl
file contains the total number of system call information, which will
be used to update NR_syscalls.
The macro name also changed form NR_syscalls to __NR_syscalls for
making the name convention same across all architecture. While
__NR_syscalls isn't strictly part of the uapi, having it as part of
the generated header to simplifies the implementation.
