Subject: linux-next: build failure in Linus' tree

Hi Linus,

After merging the gcl-current tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

kernel/built-in.o: In function `.copy_process':
fork.c:(.text+0x14c34): undefined reference to `.__node_random'
fork.c:(.text+0x14c44): undefined reference to `.__node_random'

Caused by commit 0ac0c0d0f837c499afd02a802f9cf52d3027fa3b ("cpusets:
randomize node rotor used in cpuset_mem_spread_node()").

This commit assumes that __node_random() exists if (MAX_NUMNODES > 1) and
uses it if CONFIG_CPUSETS is set, but only creates it for x86 ...  there
is at least one other architecture where those conditions are true.

Cheers,
Stephen Rothwell                    sfr@...b.auug.org.au
