2010-12-10USB: OTG: msm: Add support for power managementPavankumar Kondeti
Implement runtime and system pm ops to put hardware into low power mode (LPM). As part of LPM, USB clocks are turned off, PHY is put into suspend state and PHY comparators are turned off if VBUS/Id notifications are not required from PHY.

2010-12-10USB: EHCI: msm: Add support for power managementPavankumar Kondeti
Enable runtime PM and mark no_callbacks flag. OTG device, parent of HCD takes care of putting hardware into low power mode. Adjust port power wakeup flags during system suspend and resume. Signed-off-by: Pavankumar Kondeti <pkondeti@codeaurora.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2010-12-10USB: EHCI: Add MSM Host Controller driverPavankumar Kondeti
This patch adds support for EHCI compliant HSUSB Host controller found on MSM chips. The root hub has a single port and TT is built into it. This driver depends on OTG driver for PHY initialization, clock management and powering up VBUS.

2010-12-10USB: Add MSM OTG Controller driverPavankumar Kondeti
This driver implements PHY initialization, clock management, ULPI IO ops and simple OTG state machine to kick host/peripheral based on Id/VBUS line status. VBUS/Id lines are tied to a reference voltage on some boards. Hence provide debugfs interface to select host/peripheral mode.

2010-12-10USB: EHCI: ASPM quirk of ISOC on AMD SB800Alex He
When ASPM PM Feature is enabled on UMI link, devices that use ISOC stream of data transfer may be exposed to longer latency causing less than optimal per- formance of the device. The longer latencies are normal and are due to link wake time coming out of low power state which happens frequently to save power when the link is not active. The following code will make exception for certain features of ASPM to be by passed and keep the logic normal state only when the ISOC device is connected and active. This change will allow the device to run at optimal performance yet minimize the impact on overall power savings.

2010-12-10USB: otg: fix link breakage, when the NOP USB Xceiver is a moduleGuennadi Liakhovetski
If the NOP USB OTG transceiver driver is built as a module, the otg.h header declares external functions, but if they are referenced from the kernel proper, as, e.g., in the OMAP3 case, where the omap3evm board is calling the usb_nop_xceiv_register() function, linkage breaks.

2010-12-10usb: gadget/imx-udc: fix interrupt name againUwe Kleine-König
Commit 06c3859 (usb: gadget/imx-udc: remove usage of deprecated symbol USBD_INT0) was a bit precipitant because the name used instead didn't match the usual naming scheme for irqs on arm/imx. I renamed the irq to the right name in e083000 (ARM: imx: dynamically allocate imx_udc device) when 06c3859 didn't hit Linus' tree, so I missed to add a compat #define. This patch allows compiling imx_udc.c with and without e083000. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2010-12-10Btrfs: pwrite blocked when writing from the mmaped buffer of the same pageXin Zhong
This problem is found in meego testing: http://bugs.meego.com/show_bug.cgi?id=6672 A file in btrfs is mmaped and the mmaped buffer is passed to pwrite to write to the same page of the same file. In btrfs_file_aio_write(), the pages is locked by prepare_pages(). So when btrfs_copy_from_user() is called, page fault happens and the same page needs to be locked again in filemap_fault(). The fix is to move iov_iter_fault_in_readable() before prepage_pages() to make page fault happen before pages are locked. And also disable page fault in critical region in btrfs_copy_from_user().

2010-12-10sfc: Remove ancient support for nesting of TX stopBen Hutchings
Long before this driver went into mainline, it had support for multiple TX queues per port, with lockless TX enabled. Since Linux did not know anything of this, filling up any hardware TX queue would stop the core TX queue and multiple hardware TX queues could fill up before the scheduler reacted. Thus it was necessary to keep a count of how many TX queues were stopped and to wake the core TX queue only when all had free space again. The driver also previously (ab)used the per-hardware-queue stopped flag as a counter to deal with various things that can inhibit TX, but it no longer does that. Remove the per-channel tx_stop_count, tx_stop_lock and per-hardware-queue stopped count and just use the networking core queue state directly. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>

2010-12-10r8169: Fix runtime power managementRafael J. Wysocki
I noticed that one of the post-2.6.36 patches broke runtime PM of the r8169 on my MSI Wind test machine in such a way that the link was not brought up after reconnecting the network cable. In the process of debugging the issue I realized that we only should invoke the runtime PM functions in rtl8169_check_link_status() when link change is reported and if we do so, the problem goes away. Moreover, this allows rtl8169_runtime_idle() to be simplified quite a bit. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Acked-by: Francois Romieu <romieu@fr.zoreil.com> Signed-off-by: David S.

2010-12-10NFS: Fix panic after nfs_umount()Chuck Lever
After a few unsuccessful NFS mount attempts in which the client and server cannot agree on an authentication flavor both support, the client panics. nfs_umount() is invoked in the kernel in this case. Turns out nfs_umount()'s UMNT RPC invocation causes the RPC client to write off the end of the rpc_clnt's iostat array. This is because the mount client's nrprocs field is initialized with the count of defined procedures (two: MNT and UMNT), rather than the size of the client's proc array (four). The fix is to use the same initialization technique used by most other upper layer clients in the kernel. Introduced by commit 0b524123, which failed to update nrprocs when support was added for UMNT in the kernel.
