This breaks irqs on PowerMac G5. I see lost irq errors from the sata
driver.

Note that the breakage only started after the series was merged into
mainline. But when transplanted upon the parent of the merge this is
the commit that was blamed by bisect. So something changed between
v3.3-rc3 and the merge of this series that broke it.
