commit 3e71da19 upstream. bytesperline should be the bytesperline for the first plane for planar formats, not that of all planes combined. This fixes a crash in xawtv caused by the wrong bpl. BugLink: https://bugzilla.redhat.com/show_bug.cgi?id=1305389Reported-and-tested-by:

commit b339a72e upstream. The V4L2_CID_TX_EDID_PRESENT control reports if an EDID is present. The adv7511 however still reported the EDID present after disconnecting the HDMI cable. Fix the logic regarding this control. And when the EDID is disconnected also call ADV7511_EDID_DETECT to notify the bridge driver. This was also missing. Signed-off-by:

commit 8e580411 upstream. The davinci platform has tried to get support for the EEPROM right, but failed to get a clean build so far. At the moment, we get a warning whenever CONFIG_SYSFS is disabled, as that is needed by EEPROM_AT24: warning: (MACH_DAVINCI_EVM && MACH_SFFSDR && MACH_DAVINCI_DM6467_EVM && MACH_DAVINCI_DM365_EVM && MACH_DAVINCI_DA830_EVM && MACH_MITYOMAPL138 && MACH_MINI2440) selects EEPROM_AT24 which has unmet direct dependencies (I2C && SYSFS) Kevin Hilman initially added the 'select' to ensure that EEPROM_AT24 is always enabled in machines that really want it for normal operation (i.e. for reading the MAC address). This broke when I2C was disabled, and Russell King followed up with another patch to select that as well. I now see that the SYSFS dependency is still missing, which leaves us with three options: a) add 'select SYSFS' in addition to the others b) change AT24_EEPPROM to work without sysfs (should be possible) c) remove all those selects again and get the files to build when I2C is disabled. I would really hate to do a) because adding select statements that hardwire user-selectable symbols is generally a bad idea. I first tried b) but then ended up redoing the patch from scratch to approach c), so we can also remove the other selects. I checked that CONFIG_I2C is still enabled with davinci_all_defconfig, so that does not have to change. Signed-off-by:

commit e07ff943 upstream. The s5m8767_pmic_probe() function calls s5m8767_get_register() to read data without checking the return code, which produces a compile-time warning when that data is accessed: drivers/regulator/s5m8767.c: In function 's5m8767_pmic_probe': drivers/regulator/s5m8767.c:924:7: error: 'enable_reg' may be used uninitialized in this function [-Werror=maybe-uninitialized] drivers/regulator/s5m8767.c:944:30: error: 'enable_val' may be used uninitialized in this function [-Werror=maybe-uninitialized] This changes the s5m8767_get_register() function to return a -EINVAL not just for an invalid register number but also for an invalid regulator number, as both would result in returning uninitialized data. The s5m8767_pmic_probe() function is then changed accordingly to fail on a read error, as all the other callers of s5m8767_get_register() already do. In practice this probably cannot happen, as we don't call s5m8767_get_register() with invalid arguments, but the gcc warning seems valid in principle, in terms writing safe error checking.

commit 4392bf33 upstream. hid_ignore_special_drivers works fine until hid_scan_report autodetects and reassign devices (for hid-multitouch, hid-microsoft and hid-rmi). Simplify the handling of the parameter: if it is there, use hid-generic, no matter what, and if not, scan the device or rely on the hid_have_special_driver table. This was detected while trying to disable hid-multitouch on a Surface Pro cover which prevented to use the keyboard. Signed-off-by:

commit 9578f41a upstream. This allows the transport layer (I have in mind hid-logitech-dj and uhid) to set the group before it is added to the hid bus. This way, it can bypass the hid_scan_report() call, and choose in advance which driver will handle the newly created hid device. Signed-off-by:

commit 5d74325a upstream. The patch that added Logitech Dual Action gamepad support forgot to update the special driver list for the device. This caused the logitech driver not to probe unless kernel module load order was favorable. Update the special driver list to fix it. Thanks to Simon Wood for the idea.

commit 264904cc upstream. Some devices I got show an inability to operate right after power on if they are already connected. They are beyond recovery if the descriptors are requested multiple times. So in case of a timeout we rather bail early and reset again. But it must be done only on the first loop lest we get into a reset/time out spiral that can be overcome with a retry. This patch is a rework of a patch that fell through the cracks. http://www.spinics.net/lists/linux-usb/msg103263.htmlSigned-off-by:

commit b3a7f31e upstream. The Armada 375 has the same SATA IP as Armada 370 and Armada XP, which requires the PHY speed to be set in the LP_PHY_CTL register for SATA hotplug to work. Therefore, this commit updates the compatible string used to describe the SATA IP in Armada 375 from marvell,orion-sata to marvell,armada-370-sata.

commit 401879c5 upstream. The N_IRDA line discipline may access the previous line discipline's closed and already-fre private data on open [1]. The tty->disc_data field _never_ refers to valid data on entry to the line discipline's open() method. Rather, the ldisc is expected to initialize that field for its own use for the lifetime of the instance (ie. from open() to close() only).

commit da6ccaaa upstream. Make the "Attempted send on closed socket" error messages generated in nbd_request_handler() ratelimited. When the nbd socket is shutdown, the nbd_request_handler() function emits an error message for every request remaining in its queue. If the queue is large, this will spam a large amount of messages to the log. There's no need for a separate error message for each request, so this patch ratelimits it. In the specific case this was found, the system was virtual and the error messages were logged to the serial port, which overwhelmed it.

commit 6b87b70c upstream. Prior to 3.13 make allmodconfig KCONFIG_ALLCONFIG=/dev/null used to be equivalent to make allmodconfig; these days it hardwires MODULES to n. In fact, any KCONFIG_ALLCONFIG that doesn't set MODULES explicitly is treated as if it set it to n. Regression had been introduced by commit cfa98f ("kconfig: do not override symbols already set"); what happens is that conf_read_simple() does sym_calc_value(modules_sym) on exit, which leaves SYMBOL_VALID set and has conf_set_all_new_symbols() skip modules_sym. It's pretty easy to fix - simply move that call of sym_calc_value() into the callers, except for the ones in KCONFIG_ALLCONFIG handling. Objections? Signed-off-by:

commit 4d107d3b upstream. imx6_pcie_link_up() previously used usleep_range() to wait for the link to come up. Since it may be called while holding the config spinlock, the sleep causes a "BUG: scheduling while atomic" error. Instead of waiting for the link to come up in imx6_pcie_link_up(), do the waiting in imx6_pcie_wait_for_link(), where we're not holding a lock and sleeping is allowed.

commit e513229b upstream. When an SMP Hyper-V guest is running on top of 2012R2 Server and secondary cpus are sent offline (with echo 0 > /sys/devices/system/cpu/cpu$cpu/online) the system freeze is observed. This happens due to the fact that on newer hypervisors (Win8, WS2012R2, ...) vmbus channel handlers are distributed across all cpus (see init_vp_index() function in drivers/hv/channel_mgmt.c) and on cpu offlining nobody reassigns them to CPU0. Prevent cpu offlining when vmbus is loaded until the issue is fixed host-side. This patch also disables hibernation but it is OK as it is also broken (MCE error is hit on resume). Suspend still works. Tested with WS2008R2 and WS2012R2. Signed-off-by:

I'm doing this without going through paravirt because this is specific to Xen PV.

commit 590ee7db upstream. Now that we are using smpboot_thread_init() in init/main.c as well, provide it for !CONFIG_SMP as well. This addresses a !CONFIG_SMP build failure. Cc: Paul E.

commit 1f041a89 upstream. struct timespec uses 'long' to present second and nanosecond. 'long' is 64 bits on 64bits machine. ceph MDS expects time stamp to be encoded as struct ceph_timespec, which uses 'u32' to present second and nanosecond. Signed-off-by:

commit 8835ba4a upstream. An attack has become available which pretends to be a quirky device circumventing normal sanity checks and crashes the kernel by an insufficient number of interfaces. This patch adds a check to the code path for quirky devices. Signed-off-by:
