Among them: - A fix for build breakage in the MTD subsystem for some PXA devices. David Woodhouse has this patch in his for-next branch but has not been responding to our requests to send it up so here it is. I should have amended the commit message to describe the build failure for CONFIG_OF=n setups, but forgot and now it's down in the stack of commits. - Added device-tree for the BeagleBone Black. Turns out people have been using the older "regualar" bone DT for the newer boards, and there's risk of damaging hardware that way. - Misc DT and regular fixes for OMAP. - Fix to make the ST-Ericsson "snowball" boards boot with multi_v7_defconfig, and enable one of the ST-E reference boards on the same config. - Kconfig cleanup for u300 to hide submenus when the platform isn't enabled. - Enable ARM_ATAG_DTB_COMPAT to let firmware override command line when booting with an appended devicetree on non-DT-enabled firmware (needed to boot snowball)" * tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (26 commits) ARM: multi_v7: add HREFv60 to multi_v7 defconfig ARM: OMAP2+: mux: fix trivial typo in name ARM: OMAP4 SMP: Corrected a typo fucntions to functions ARM: OMAP4: cpuidle: fix: call cpu_cluster_pm_exit conditionally mailbox: remove unnecessary platform_set_drvdata() ARM: mach-omap2: gpmc: Fix warning when CONFIG_ARM_LPAE=y ARM: OMAP: fix return value check in omap_device_build_from_dt() ARM: OMAP4: Fix clock_get error for GPMC during boot ARM: sa1100: collie.c: fall back to jedec_probe flash detection ARM: u300: hide submenus ARM: dts: igep00x0: Add pinmux configuration for MCBSP2 ARM: dts: Fix muxing and regulator for wl12xx on the SDIO bus for blaze ARM: dts: Fix muxing and regulator for wl12xx on the SDIO bus for pandaboard mtd: nand: pxa3xx: Remove unneeded ifdef CONFIG_OF ARM: multi_v7_defconfig: enable ARM_ATAG_DTB_COMPAT ARM: ux500: disable outer cache debug ARM: dts: OMAP5: fix ocp2scp DTS data ARM: dts: OMAP5: fix reg property size ARM: dts: am335x-bone*: add DT for BeagleBone Black ARM: dts: omap3-beagle-xm: fix string error in compatible property ... 2013-09-19T17:52:25Z Linus Torvalds torvalds@linux-foundation.org 2013-09-19T17:52:25Z urn:sha1:f05f8198e415151bc6f8369c93e25befcafe8026 Pull MIPS updates from Ralf Baechle: - Minor updates and fixes to the Octeon ethernet driver in staging - A fix to VGA_MAP_MEM() for 64 bit platforms - Fix a workaround for 74K/1074K processors - The symlink arch/mips/boot/dts/include/dt-bindings was pointing to a a file with a name ending in \n. I think this may have been caused by a git bug with with patches sent by email - A build fix for VGA console on BCM1480-based systems - Fix PCI device access via "/sys/bus/pci/.../resource0" or similar work for Alchemy platforms - Fix potential data leak on MIPS R5 cores. This doesn't add proper support for any R5 features, just ensures a kernel without such support will be secure to run - Adding a macros for the CP0 Config5 register to be used by the R5 fix - Make get_cycles() actually return something useful where possible This also requires a preparatory patch for performance sake - Fix a warning about the use of smp_processor_id() in preemptible code. Again this includes a preparatory patch adding the infrastructure to be used by the actual patch - Finally remove pointless one-line comment * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: MIPS: Fix invalid symbolic link file MIPS: PCI: pci-bcm1480: Include missing vt.h header MIPS: Disable usermode switching of the FR bit for MIPS R5 CPUs.

If an O32 application did enable FR=1 mode, some data from another application might be leaked in the extra registers becoming visible.
