2012-09-12x86: Move paging_init() call to x86_init.paging.pagetable_init()Attilio Rao
Move the paging_init() call to the platform specific pagetable_init() function, so we can get rid of the extra pagetable_setup_done() function pointer.

2012-09-12rpmsg: fix dma_free_coherent dev parameterFernando Guzman Lugo
dma_alloc/free_coherent APIs requires the platform specific remoteproc device as the device parameter. We are passing vdev->dev.parent to the dma_free_coherent function which is the generic rproc device and it is wrong, it has to be vdev->dev.parent->parent instead, same as when we call dma_alloc_coherent function.

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.

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().

This driver is for a PCI device not a legacy device. Convert it from a module_comedi_driver to a module_comedi_pci_driver. This will allow using the comedi_pci_auto_config mechanism to attach to the device.

git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next usb: musb: patches for v3.7 merge window Here we have a bunch of miscellaneous cleanups and fixes to the musb driver. It fixes a bunch of mistakes errors which nobody has triggered before, so I'm not Ccing stable tree. We are finally improving OMAP's VBUS/ID Mailbox usage so that we can introduce our PHY drivers properly. Also, we're adding support for multiple instances of the MUSB IP in the same SoC, as seen on some platforms from TI which have 2 MUSB instances. Other than that, we have some small fixes like not kicking DMA for a zero byte transfer, or properly handling NAK timeout on MUSB's host side, and the enabling of DMA Mode1 for any transfers which are aligned to wMaxPacketSize. All patches have been pending on mailing list for a long time and I don't expect any big surprises with this pull request.

git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next usb: dwc3: patches for v3.7 merge window Some much needed changes for our dwc3 driver. First there's a rework on the ep0 handling due to some Silicon issue we uncovered which affects all users of this IP core (there's a missing XferNotReady(DATA) event in some conditions). This issue which show up as a SETUP transfers which wouldn't complete ever and we would fail TD 7.06 of the Link Layer Test from USB-IF and Lecroy's USB3 Exerciser. We also fix a long standing bug regarding EP0 enable sequencing where we weren't setting a particular bit (Ignore Sequence Number). Since we never saw any problems caused by that, it didn't deserve being sent to stable tree. On this pull request we also fix Burst Size initialization which should be done only in SuperSpeed and we were mistakenly setting Burst Size to the maximum value on non-SuperSpeed mode. Again, since we never saw any problems caused by that, we're not sending this patch to stable. There's also a memory ordering fix regarding usage of bitmaps in dwc3 driver. You will also find some sparse warnings fix, a fix for missed isochronous packets when the endpoint is already busy, and a fix for synchronization delay on dwc3_stop_active_transfer().

git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next usb: xceiv: patches for v3.7 merge window nop xceiv got its own header to avoid polluting otg.h. It has also learned to work as USB2 and USB3 phys so we can use it on USB3 controllers. Together with those two changes to nop xceiv, we're adding basic PHY support to dwc3 driver, this is to allow platforms which actually have a SW-controllable PHY talk to them through dwc3 driver. We're adding a new phy driver for the OMAP architecture. This driver is for the PHY found in OMAP4 SoCs, and a new phy driver for the marvell architecture. An extra phy driver - for Tegra SoCs - is now moving from arch/arm/mach-tegra* to drivers/usb/phy. Also here, there's the creation of <linux/usb/phy.h> which should be used from now on for PHY drivers, even those which don't support OTG.

git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next usb: gadget: patches for v3.7 merge window This pull request is large but the biggest part is the first part of the cleanup on the gadget framework so we have a saner setup to add configfs support for v3.8. We have also some more conversions to the new udc_start/udc_stop which makes us closer from dropping the old interfaces. USB_GADGET_DUALSPEED and USB_GADGET_SUPERSPEED are finally gone, thanks to Michal for his awesome work. Other than that, we have the usual set of miscellaneous changes and cleanups involving improvements to debug messages, removal of duplicated includes, moving dereference after NULL test, making renesas_hsbhs' irq handler Shared, unused code being dropped, prevention of sleep-inside-spinlock bugs and a race condition fix on udc-core.
