Hi Andrew,
After merging the akpm tree, today's linux-next build (sparc64 defconfig)
failed like this:

arch/sparc/kernel/ptrace_64.c:113:20: error: 'pscr_ret__.icache_line_size' may be used uninitialized in this function [-Werror=uninitialized]
Caused by commit 5aa661aa13d4 ("sparc: replace __get_cpu_var uses").
I have reverted that commit for today.
I suspect that this whole series may need more review and work.
