From f43194e45852b0455d2a3e3730f70daa76958423 Mon Sep 17 00:00:00 2001 From: Rashmica Gupta Date: Thu, 19 Nov 2015 17:04:53 +1100 Subject: [PATCH] powerpc: Standardise on NR_syscalls rather than __NR_syscalls. Most architectures use NR_syscalls as the #define for the number of syscalls. We use __NR_syscalls, and then define NR_syscalls as __NR_syscalls. __NR_syscalls is not used outside arch code, whereas NR_syscalls is. So as NR_syscalls must be defined and __NR_syscalls does not, replace __NR_syscalls with NR_syscalls.
