Pull powerpc fixes from Ben Herrenschmidt:
"Here are a handful of small powerpc fixes.
A couple of section mismatches (always worth fixing), a missing export
of a new symbol causing build failures of modules, a page fault
deadlock fix (interestingly that bug has been around for a LONG time,
though it seems to be more easily triggered by KVM) and fixing pseries
default idle loop in the absence of the cpuidle drivers (such as
during boot)"
* 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc:
powerpc: Default arch idle could cede processor on pseries
fbdev/ps3fb: Fix section mismatch warning for ps3fb_probe
powerpc: Fix section mismatch warning for prom_rtas_call
powerpc: Fix possible deadlock on page fault
powerpc: Export cpu_to_chip_id() to fix build error
