Merge branch 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc
Pull two powerpc fixes from Ben Herrenschmidt:
"Here are a couple of fixes for 3.15. One from Anton fixes a nasty
regression I introduced when trying to fix a loss of irq_work whose
consequences is that we can completely lose timer interrupts on a
CPU... not pretty.
The other one is a change to our PCIe reset hook to use a firmware
call instead of direct config space accesses to trigger a fundamental
reset on the root port. This is necessary so that the FW gets a
chance to disable the link down error monitoring, which would
otherwise trip and cause subsequent fatal EEH error"
* 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc:
powerpc: irq work racing with timer interrupt can result in timer interrupt hang
powerpc/powernv: Reset root port in firmware
