Hi Rafael,

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

kernel/power/process.c: In function 'thaw_kernel_threads':
kernel/power/process.c:199:2: error: 'g' undeclared (first use in this function)
kernel/power/process.c:199:2: note: each undeclared identifier is reported only once for each function it appears in
kernel/power/process.c:199:2: error: 'p' undeclared (first use in this function)

Caused by commit 625278ca8016 ("PM / QoS: Simplify PM QoS expansion/merge").

Clearly never built :-(  At least, not in this form.

I have used the pm tree from next-20120125 for today.
