Andrew's patch works_for_me. (Ack)


During the build, I got another (unrelated) build error:

kernel/built-in.o: In function `copy_process':
fork.c:(.text+0x162b6): undefined reference to `__node_random'
fork.c:(.text+0x162cd): undefined reference to `__node_random'

kernel/fork.c needs to #include <linux/nodemask.h>

[builds...]

But that is not enough. The config file has CONFIG_CPUSETS=y
and CONFIG_NUMA=n, so __node_random() is not being built at all.
