2014-09-03ARM: dts: dra7-evm: Fix 8th NAND partition's nameRoger Quadros
The 8th NAND partition should be named "NAND.u-boot-env.backup1" instead of "NAND.u-boot-env". This is to be consistent with other TI boards as well as u-boot.

2014-09-03ACPI / cpuidle: fix deadlock between cpuidle_lock and cpu_hotplug.lockJiri Kosina
There is a following AB-BA dependency between cpu_hotplug.lock and cpuidle_lock: 1) cpu_hotplug.lock -> cpuidle_lock enable_nonboot_cpus() _cpu_up() cpu_hotplug_begin() LOCK(cpu_hotplug.lock) cpu_notify() ... acpi_processor_hotplug() cpuidle_pause_and_lock() LOCK(cpuidle_lock) 2) cpuidle_lock -> cpu_hotplug.lock acpi_os_execute_deferred() workqueue ... acpi_processor_cst_has_changed() cpuidle_pause_and_lock() LOCK(cpuidle_lock) get_online_cpus() LOCK(cpu_hotplug.lock) Fix this by reversing the order acpi_processor_cst_has_changed() does thigs -- let it first execute the protection against CPU hotplug by calling get_online_cpus() and obtain the cpuidle lock only after that (and perform the symmentric change when allowing CPUs hotplug again and dropping cpuidle lock).

2014-09-03ACPI / scan: not cache _SUN value in struct acpi_device_pnpYasuaki Ishimatsu
The _SUN device indentification object is not guaranteed to return the same value every time it is executed, so we should not cache its return value, but rather execute it every time as needed. If it is cached, an incorrect stale value may be used in some situations. This issue was exposed by commit 202317a573b2 (ACPI / scan: Add acpi_device objects for all device nodes in the namespace). Fix it by avoiding to cache the return value of _SUN.

2014-09-03clk: prevent erronous parsing of children during rate changeTero Kristo
In some cases, clocks can switch their parent with clk_set_rate, for example clk_mux can do this in some cases. Current implementation of clk_change_rate uses un-safe list iteration on the clock children, which will cause wrong clocks to be parsed in case any of the clock children change their parents during the change rate operation. Fixed by using the safe list iterator instead. The problem was detected due to some divide by zero errors generated by clock init on dra7-evm board, see discussion under http://article.gmane.org/gmane.linux.ports.arm.kernel/349180 for details.

2014-09-03arm64: use irq_set_affinity with force=false when migrating irqsSudeep Holla
The arm64 interrupt migration code on cpu offline calls irqchip.irq_set_affinity() with the argument force=true. Originally this argument had no effect because it was not used by any interrupt chip driver and there was no semantics defined. This changed with commit 01f8fa4f01d8 ("genirq: Allow forcing cpu affinity of interrupts") which made the force argument useful to route interrupts to not yet online cpus without checking the target cpu against the cpu online mask. The following commit ffde1de64012 ("irqchip: gic: Support forced affinity setting") implemented this for the GIC interrupt controller. As a consequence the cpu offline irq migration fails if CPU0 is offlined, because CPU0 is still set in the affinity mask and the validation against cpu online mask is skipped to the force argument being true. The following first_cpu(mask) selection always selects CPU0 as the target. Commit 601c942176d8("arm64: use cpu_online_mask when using forced irq_set_affinity") intended to fix the above mentioned issue but introduced another issue where affinity can be migrated to a wrong CPU due to unconditional copy of cpu_online_mask. As with for arm, solve the issue by calling irq_set_affinity() with force=false from the CPU offline irq migration code so the GIC driver validates the affinity mask against CPU online mask and therefore removes CPU0 from the possible target candidates. Also revert the changes done in the commit 601c942176d8 as it's no longer needed. Tested on Juno platform.

2014-09-03toshiba_acpi: fix and cleanup toshiba_kbd_bl_mode_store()Dan Carpenter
The current code just returns -EINVAL because mode can't be equal to both 1 and 2. Also this function is messy so I have cleaned it up: 1) Remove initializers like "int time = -1". Initializing variables to garbage values turns off GCC's uninitialized variable warnings so it can lead to bugs. 2) Use kstrtoint() instead of sscanf(). 3) Use SCI_KBD_MODE_FNZ and SCI_KBD_MODE_AUTO instead of magic numbers 1 and 2. 4) Don't check for "mode == -1" because that can't happen. 5) Preserve the error code from toshiba_kbd_illum_status_set().

In blk-mq.c blk_mq_alloc_tag_set, if: set->tags = kmalloc_node() succeeds, but one of the blk_mq_init_rq_map() calls fails, goto out_unwind; needs to free set->tags so the caller is not obligated to do so. None of the current callers (null_blk, virtio_blk, virtio_blk, or the forthcoming scsi-mq) do so. set->tags needs to be set to NULL after doing so, so other tag cleanup logic doesn't try to free a stale pointer later.

2014-09-03[media] smiapp: Set sub-device ownerSakari Ailus
The smiapp driver is the owner of the sub-devices exposed by the smiapp driver. This prevents unloading the module whilst it's in use. Signed-off-by: Sakari Ailus <sakari.ailus@linux.intel.com> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
2014-09-03[media] smiapp: Fix power count handlingSakari Ailus
The sensor may be powered by either one of its sub-devices being accessed from the user space (an open file handle) or by its s_power() op being called with non-zero on argument. The driver counts the users and if any reason to keep the device powered exists it will be powered. However, a faulty condition was used in recognising the need to power off the sensor, leading it to be powered off every time any of its uses went away.

2014-09-03nl80211: clear skb cb before passing to netlinkJohannes Berg
In testmode and vendor command reply/event SKBs we use the skb cb data to store nl80211 parameters between allocation and sending. This causes the code for CONFIG_NETLINK_MMAP to get confused, because it takes ownership of the skb cb data when the SKB is handed off to netlink, and it doesn't explicitly clear it. Clear the skb cb explicitly when we're done and before it gets passed to netlink to avoid this issue.

2014-09-03powerpc/kvm/cma: Fix panic introduces by signed shift operationLaurent Dufour
fc95ca7284bc54953165cba76c3228bd2cdb9591 introduces a memset in kvmppc_alloc_hpt since the general CMA doesn't clear the memory it allocates. However, the size argument passed to memset is computed from a signed value and its signed bit is extended by the cast the compiler is doing. This lead to extremely large size value when dealing with order value >= 31, and almost all the memory following the allocated space is cleaned. As a consequence, the system is panicing and may even fail spawning the kdump kernel. This fix makes use of an unsigned value for the memset's size argument to avoid sign extension. Among this fix, another shift operation which may lead to signed extended value too is also fixed.

2014-09-03video: fix composite video connector compatible stringTomi Valkeinen
The quite-recently-added analog-tv-connector bindings say that the compatible string for composite video connector is "composite-connector". That string is also used in the omap3-n900.dts file. However, the connector driver uses "composite-video-connector", so this has never worked. While changing the driver's compatible string to "composite-connector" would be safer, as published DT bindings should not be changed, I'd rather fix the bindings in this case for two reasons: * composite-connector is a bit too generic name, as it doesn't even hint at video. * it's clear that this has never worked, which means no one has used those bindings, which should make it safe to change this.

2014-09-03PEFILE: Relax the check on the length of the PKCS#7 certDavid Howells
Relax the check on the length of the PKCS#7 cert as it appears that the PE file wrapper size gets rounded up to the nearest 8. The debugging output looks like this: PEFILE: ==> verify_pefile_signature() PEFILE: ==> pefile_parse_binary() PEFILE: checksum @ 110 PEFILE: header size = 200 PEFILE: cert = 968 @547be0 [68 09 00 00 00 02 02 00 30 82 09 56 ] PEFILE: sig wrapper = { 968, 200, 2 } PEFILE: Signature data not PKCS#7 The wrapper is the first 8 bytes of the hex dump inside []. This indicates a length of 0x968 bytes, including the wrapper header - so 0x960 bytes of payload. The ASN.1 wrapper begins [ ... 30 82 09 56 ]. That indicates an object of size 0x956 - a four byte discrepency, presumably just padding for alignment purposes. So we just check that the ASN.1 container is no bigger than the payload and reduce the recorded size appropriately. Whilst we're at it, allow shorter PKCS#7 objects that manage to squeeze within 127 or 255 bytes. It's just about conceivable if no X.509 certs are included in the PKCS#7 message.
