2016-02-17s390/dasd: fix performance dropStefan Haberland
Commit ca369d51b ("sd: Fix device-imposed transfer length limits") introduced a new queue limit max_dev_sectors which limits the maximum sectors for requests. The default value leads to small dasd requests and therefor to a performance drop. Set the max_dev_sectors value to the same value as the max_hw_sectors to use the maximum available request size for DASD devices.

2016-02-11s390/dasd: prevent incorrect length error under z/VM after PAV changesStefan Haberland
The channel checks the specified length and the provided amount of data for CCWs and provides an incorrect length error if the size does not match. Under z/VM with simulation activated the length may get changed. Having the suppress length indication bit set is stated as good CCW coding practice and avoids errors under z/VM.

2016-02-05regmap: mmio: Revert to v4.4 endianness handlingMark Brown
Commit 29bb45f25ff3 (regmap-mmio: Use native endianness for read/write) attempted to fix some long standing bugs in the MMIO implementation for big endian systems caused by duplicate byte swapping in both regmap and readl()/writel() which affected MIPS systems as when they are in big endian mode they flip the endianness of all registers in the system, not just the CPU. MIPS systems had worked around this by declaring regmap using IPs as little endian which is inaccurate, unfortunately the issue had not been reported. Sadly the fix makes things worse rather than better. By changing the behaviour to match the documentation it caused behaviour changes for other IPs which broke them and by using the __raw I/O accessors to avoid the endianness swapping in readl()/writel() it removed some memory ordering guarantees and could potentially generate unvirtualisable instructions on some architectures. Unfortunately sorting out all this mess in any half way sensible fashion was far too invasive to go in during an -rc cycle so instead let's go back to the old broken behaviour for v4.5, the better fixes are already queued for v4.6. This does mean that we keep the broken MIPS DTs for another release but that seems the least bad way of handling the situation.

This is needed to properly deallocate port payload after downstream branch get unplugged. In order to do this unplugged MST topology should be preserved, to find first alive port on path to unplugged MST topology, and send payload deallocation request to branch device of found port. For this mstb and port kref's are used in reversed order to track when port and branch memory could be freed. Added additional functions to find appropriate mstb as described above.

2016-02-04xhci: harden xhci_find_next_ext_cap against device removalJoe Lawrence
xhci_find_next_ext_cap doesn't check for PCI hotplug removal and may use the PCI master abort bit pattern (~0) to calculate a new PCI address offset to read/write. The has lead to reproducable crashes when testing surprise removal during device initialization on a Stratus platform, at least after commit d5ddcdf4d672 ("xhci: rework xhci extended capability list parsing functions"). The crash is repeatable on a Stratus platform when injecting hardware faults to induce xHCI host controller hotplug during driver initialization. If a PCI read in xhci_find_next_ext_cap returns the master abort pattern, quirk_usb_handoff_xhci may start using a bogus ext_cap_offset to start searching more bogus PCI addresses.

2016-02-04[media] vb2-core: call threadio->fnc() if !VB2_BUF_STATE_ERRORMauro Carvalho Chehab
changeset 70433a152f0 ("media: videobuf2: Refactor vb2_fileio_data and vb2_thread") broke videobuf2-dvb. The root cause is that, instead of calling threadio->fnc() for all types of events except for VB2_BUF_STATE_ERROR, it was calling it only for VB2_BUF_STATE_DONE. With that, the DVB thread were never called. Cc: stable@vger.kernel.org # Kernel >= 4.3 Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
2016-02-04[media] vb2: fix nasty vb2_thread regressionHans Verkuil
The vb2_thread implementation was made generic and was moved from videobuf2-v4l2.c to videobuf2-core.c in commit af3bac1a. Unfortunately that clearly was never tested since it broke read() causing NULL address references. The root cause was confused handling of vb2_buffer vs v4l2_buffer (the pb pointer in various core functions). The v4l2_buffer no longer exists after moving the code into the core and it is no longer needed. However, the vb2_thread code passed a pointer to a vb2_buffer to the core functions were a v4l2_buffer pointer was expected and vb2_thread expected that the vb2_buffer fields would be filled in correctly. This is obviously wrong since v4l2_buffer != vb2_buffer. Note that the pb pointer is a void pointer, so no type-checking took place. This patch fixes this problem: 1) allow pb to be NULL for vb2_core_(d)qbuf. The vb2_thread code will use a NULL pointer here since they don't care about v4l2_buffer anyway. 2) let vb2_core_dqbuf pass back the index of the received buffer. This is all vb2_thread needs: this index is the index into the q->bufs array and vb2_thread just gets the vb2_buffer from there. 3) the fileio->b pointer (that originally contained a v4l2_buffer) is removed altogether since it is no longer needed. Tested with vivid and the cobalt driver.

2016-02-04[media] tda1004x: only update the frontend properties if lockedMauro Carvalho Chehab
The tda1004x was updating the properties cache before locking. If the device is not locked, the data at the registers are just random values with no real meaning. This caused the driver to fail with libdvbv5, as such library calls GET_PROPERTY from time to time, in order to return the DVB stats.

xhci driver frees data for all devices, both usb2 and and usb3 the first time usb_remove_hcd() is called, including td_list and and xhci_ring structures. When usb_remove_hcd() is called a second time for the second xhci bus it will try to dequeue all pending urbs, and touches td_list which is already freed for that endpoint.

2016-02-03usb: xhci-mtk: fix AHB bus hang up caused by roothubs pollingChunfeng Yun
when ip fails to enter sleep mode, register access protection will be disabled, at the same time if all clocks are disabled, access register will hang up AHB bus. the common case causes ip sleep failure is that after all ports enter U3 but before ip enters sleep mode, a port receives a resume signal('K'). this will happens when such as clicks mouse to try to do remote-wakeup to stop system enter suspend. so stop polling root hubs to avoid access xHCI register on bus suspend, and restart it when bus resumes.

XHCI_SSIC_PORT_UNUSED quirk was applied to the xHCI host controllers in some Intel SoC chips. With this quirk applied, SSIC port is set to "unused" prior to xhci_suspend(). This may cause problem if host fails to suspend. In this case, the port is set to unused without host further entering D3, and the port will not be usable anymore.
