2015-02-20Btrfs: fix allocation size calculations in alloc_btrfs_bioChris Mason1-1/+8
Since commit 8e5cfb55d3f (Btrfs: Make raid_map array be inlined in btrfs_bio structure), the raid map array is allocated along with the btrfs bio in alloc_btrfs_bio. The calculation used to decide how much we need to allocate was using the wrong parameter passed into the allocation function. The passed in real_stripes will be zero if a target replace operation is not currently running. We want to use total_stripes instead.

2015-02-20MIPS: Alchemy: Fix cpu clock calculationManuel Lauss1-0/+2
The current code uses bits 0-6 of the sys_cpupll register to calculate core clock speed. However this is only valid on Au1300, on all earlier models the hardware only uses bits 0-5 to generate core clock. This fixes clock calculation on the MTX1 (Au1500), where bit 6 of cpupll is set as well, which ultimately lead the code to calculate a bogus cpu core clock and also uart base clock down the line.

2015-02-20ARM: 8305/1: DMA: Fix kzalloc flags in __iommu_alloc_buffer()Alexandre Courbot1-1/+1
There doesn't seem to be any valid reason to allocate the pages array with the same flags as the buffer itself. Doing so can eventually lead to the following safeguard in mm/slab.c's cache_grow() to be hit: if (unlikely(flags & GFP_SLAB_BUG_MASK)) { pr_emerg("gfp: %un", flags & GFP_SLAB_BUG_MASK); BUG(); } This happens when buffers are allocated with __GFP_DMA32 or __GFP_HIGHMEM. Fix this by allocating the pages array with GFP_KERNEL to follow what is done elsewhere in this file. Using GFP_KERNEL in __iommu_alloc_buffer() is safe because atomic allocations are handled by __iommu_alloc_atomic().

git://git.kernel.org/pub/scm/linux/kernel/git/evalenti/linux-soc-thermal Pull more thermal managament updates from Zhang Rui: "Specifics: - Exynos thermal driver refactoring. Several cleanups, code optimization, unused symbols removal, and unused feature removal in Exynos thermal driver. Thanks Lukasz for this effort. - Exynos thermal driver support to OF thermal. After the code refactoring, the driver earned the support to OF thermal. Chip thermal data were moved from driver code to DTS, reducing the code footprint. Thanks Lukasz for this. - After receiving the OF thermal support, the exynos thermal driver now must allow modular build. Thanks Arnd for detecting, reporting and fixing this. - Exynos thermal driver support to Exynos 7 SoC. Thanks Abhilash for this. - Accurate temperature reporting on Rockchip thermal driver, thanks to Caesar. - Fix on how OF thermal enables its zones, thanks Lukasz for fixing. - Fixes in OF thermal examples under Documentation/. Thanks Srinivas for fixing" * 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/evalenti/linux-soc-thermal: thermal: exynos: Add TMU support for Exynos7 SoC dts: Documentation: Add documentation for Exynos7 SoC thermal bindings cpufreq: exynos: allow modular build thermal: Fix examples in DT documentation thermal: exynos: Correct sanity check at exynos_report_trigger() function thermal: Kconfig: Remove config for not used EXYNOS_THERMAL_CORE thermal: exynos: Remove exynos_tmu_data.c file thermal: rockchip: make temperature reporting much more accurate thermal: exynos: Remove exynos_thermal_common.[c|h] files thermal: samsung: core: Exynos TMU rework to use device tree for configuration dts: Documentation: Update exynos-thermal.txt example for Exynos5440 dts: Documentation: Extending documentation entry for exynos-thermal cpufreq: exynos: Use device tree to determine if cpufreq cooling should be registered thermal: exynos: Modify exynos thermal code to use device tree for cpu cooling configuration thermal: exynos: Provide thermal_exynos.h file to be included in device tree files thermal: exynos: cosmetic: Correct comment format thermal: of: Enable thermal_zoneX when sensor is correctly added
2015-02-20NVMe: Fix potential corruption on sync commandsKeith Busch1-29/+3
This makes all sync commands uninterruptible and schedules without timeout so the controller either has to post a completion or the timeout recovery fails the command. This fixes potential memory or data corruption from a command timing out too early or woken by a signal. Previously any DMA buffers mapped for that command would have been released even though we don't know what the controller is planning to do with those addresses.

2015-02-20NVMe: Remove unused variablesKeith Busch1-8/+0
We don't track queues in a llist, subscribe to hot-cpu notifications, or internally retry commands. Delete the unused artifacts. Signed-off-by: Keith Busch <keith.busch@intel.com>
