2014-01-13PCI: Add global pci_lock_rescan_remove()Rafael J. Wysocki
There are multiple PCI device addition and removal code paths that may be run concurrently with the generic PCI bus rescan and device removal that can be triggered via sysfs. If that happens, it may lead to multiple different, potentially dangerous race conditions. The most straightforward way to address those problems is to run the code in question under the same lock that is used by the generic rescan/remove code in pci-sysfs.c. To prepare for those changes, move the definition of the global PCI remove/rescan lock to probe.c and provide global wrappers, pci_lock_rescan_remove() and pci_unlock_rescan_remove(), allowing drivers to manipulate that lock. Also provide pci_stop_and_remove_bus_device_locked() for the callers of pci_stop_and_remove_bus_device() who only need to hold the rescan/remove lock around it. Signed-off-by: Rafael J.

2014-01-13tty/serial: at91: disable uart timer at start of shutdownMarek Roszko
The uart timer will schedule a tasklet when it fires. It is possible that it can fire inside _shutdown before it is killed in the dma and pdc cleanup routines. This causes a tasklet that exists after the port is shutdown, so when the kernel finally executes it, it panics as the tty port is NULL. This is a somewhat rare condition but its possible if a program keeps on opening/closing the port. It has been observed in particular with systemd boot messages that were causing a kernel panic because of this behavior. Moving the timer deletion to the beginning of the function stops a tasklet from being scheduled unexpectedly.

2014-01-13usb: chipidea: udc: using MultO at TD as real mult value for ISO-TXPeter Chen
We have met a bug that the high bandwidth ISO-TX transfer has failed at the last packet if it is less than 1024, the TD status shows it is "Transaction Error". The root cause of this problem is: the mult value at qh is not correct for current TD's transfer length. We use TD list to queue un-transfer TDs, and change mult for new adding TDs. If new adding TDs transfer length less than 1024, but the queued un-transfer TDs transfer length is larger than 1024, the transfer error will occur, and vice versa. Usually, this problem occurs at the last packet, and the first packet for new frame. We fixed this problem by setting Mult at QH as the largest value (3), and set MultO (Multiplier Override) at TD according to every transfer length. It can cover both hardware version less than 2.3 (the real mult is MultO if it is not 0) and 2.3+ (the real mult is min(qh.mult, td.multo)). Since the MultO bits are only existed at TX TD, we keep the ISO-RX behavior unchanged. For stable tree: 3.11+.

2014-01-13usb: chipidea: need to mask INT_STATUS when write otgscPeter Chen
For otgsc, both enable bits and status bits are in it. So we need to make sure the status bits are not be cleared when write enable bits. It can fix one bug that we plug in/out Micro AB cable fast, and sometimes, the IDIS will be cleared wrongly when handle last ID interrupt (ID 0->1), so the current interrupt will not occur.

2014-01-13usb: chipidea: put hw_phymode_configure before ci_usb_phy_initChris Ruehl
hw_phymode_configure configures the PORTSC registers and allow the following phy_inits to operate on the right parameters. This fix a problem where the UPLI (ISP1504) could not be detected, because the Viewport was not available and read the viewport return 0's only.

2014-01-13usb: chipidea: add freescale imx28 special write register methodPeter Chen
According to Freescale imx28 Errata, "ENGR119653 USB: ARM to USB register error issue", All USB register write operations must use the ARM SWP instruction. So, we implement special hw_write and hw_test_and_clear for imx28. Discussion for it at below: http://marc.info/?l=linux-usb&m=137996395529294&w=2 This patch is needed for stable tree 3.11+.

2014-01-13usb: ehci: add freescale imx28 special write register methodPeter Chen
According to Freescale imx28 Errata, "ENGR119653 USB: ARM to USB register error issue", All USB register write operations must use the ARM SWP instruction. So, we implement a special ehci_write for imx28. Discussion for it at below: http://marc.info/?l=linux-usb&m=137996395529294&w=2 Without this patcheset, imx28 works unstable at high AHB bus loading. If the bus loading is not high, the imx28 usb can work well at the most of time. There is a IC errata for this problem, usually, we consider IC errata is a problem not a new feature, and this workaround is needed for that, so we need to add them to stable tree 3.11+.
