Hi Andrew,

After merging the akpm-current tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:

arch/arm/kernel/entry-common.S: Assembler messages:
arch/arm/kernel/entry-common.S:108: Error: __NR_syscalls is not equal to the size of the syscall table

Caused by commit

d221fc1f0f25 ("mm: mlock: add new mlock, munlock, and munlockall system calls")

I have added the following fix patch for today:

From: Stephen Rothwell <sfr@canb.auug.org.au>
Date: Thu, 16 Jul 2015 14:58:53 +1000
Subject: [PATCH] mm: mlock: fix for add new mlock, munlock, and munlockall system calls
