[PATCH 4/6] alpha: Replace NR_SYSCALLS macro from asm/unistd.h
From: Firoz Khan
Date: Mon Jul 16 2018 - 06:24:58 EST
Replace NR_SYSCALLS from asm/unistd.h and keep equivalent macro
__NR_syscalls in uapi/asm/unistd.h and this will make a unified
implementation across all the architecture and we can use a system
call generation script to generate __NR_syscalls.
While __NR_syscalls isn't strictly part of the uapi, having it as
part of the generated header to simplifies the implementation.
