git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq Pull workqueue fixes from Tejun Heo: "It's later than I'd like but well the timing just didn't work out this time. There are three bug fixes. One from before 3.6-rc1 and two from the new CPU hotplug code. Kudos to Lai for discovering all of them and providing fixes. * Atomicity bug when clearing a flag and setting another. The two operation should have been atomic but wasn't. This bug has existed for a long time but is unlikely to have actually happened. Fix is safe. Marked for -stable. * If CPU hotplug cycles happen back-to-back before workers finish the previous cycle, the states could get out of sync and it could get stuck. Fixed by waiting for workers to complete before finishing hotplug cycle. * While CPU hotplug is in progress, idle workers could be depleted which can then lead to deadlock. I think both happening together is highly unlikely but still better to fix it and the fix isn't too scary. There's another workqueue related regression which reported a few days ago: https://bugzilla.kernel.org/show_bug.cgi?id=47301 It's a bit of head scratcher but there is a semi-reliable reproduce case, so I'm hoping to resolve it soonish." * 'for-3.6-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq: workqueue: fix possible idle worker depletion across CPU hotplug workqueue: restore POOL_MANAGING_WORKERS workqueue: fix possible deadlock in idle worker rebinding workqueue: move WORKER_REBIND clearing in rebind_workers() to the end of the function workqueue: UNBOUND -> REBIND morphing in rebind_workers() should be atomic

2012-09-11powerpc/powernv: I/O and memory alignment for P2P bridgesGavin Shan
The patch implements ppc_md.pcibios_window_alignment for powernv platform so that the resource reassignment in PCI core will be done according to the I/O and memory alignment returned from powernv platform. The alignments returned from powernv platform is closely depending on the scheme for PE segmenting. Besides, the patch isn't useful for now, but the subsequent patches will be working based on it.

This patch changes pbus_size_io() and pbus_size_mem() to do window (I/O, memory and prefetchable memory) reassignment based on the minimal alignments for the P2P bridge, which was retrieved by window_alignment().

2012-09-11PCI: Add weak pcibios_window_alignment() interfaceGavin Shan
This patch implements a weak function to return the default I/O or memory window alignment for a P2P bridge. By default, I/O windows are aligned to 4KiB or 1KiB and memory windows are aligned to 4MiB. Some platforms, e.g., powernv, have special alignment requirements and can override pcibios_window_alignment().
