Merge branch 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm

Pull ARM updates from Russell King: - clang assembly fixes from Ard - optimisations and cleanups for Aurora L2 cache support - efficient L2 cache support for secure monitor API on Exynos SoCs - debug menu cleanup from Daniel Thompson to allow better behaviour for multiplatform kernels - StrongARM SA11x0 conversion to irq domains, and pxa_timer - kprobes updates for older ARM CPUs - move probes support out of arch/arm/kernel to arch/arm/probes - add inline asm support for the rbit (reverse bits) instruction - provide an ARM mode secondary CPU entry point (for Qualcomm CPUs) - remove the unused ARMv3 user access code - add driver_override support to AMBA Primecell bus * 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm: (55 commits) ARM: 8256/1: driver coamba: add device binding path 'driver_override' ARM: 8301/1: qcom: Use secondary_startup_arm() ARM: 8302/1: Add a secondary_startup that assumes ARM mode ARM: 8300/1: teach __asmeq that r11 == fp and r12 == ip ARM: kprobes: Fix compilation error caused by superfluous '*' ARM: 8297/1: cache-l2x0: optimize aurora range operations ARM: 8296/1: cache-l2x0: clean up aurora cache handling ARM: 8284/1: sa1100: clear RCSR_SMR on resume ARM: 8283/1: sa1100: collie: clear PWER register on machine init ARM: 8282/1: sa1100: use handle_domain_irq ARM: 8281/1: sa1100: move GPIO-related IRQ code to gpio driver ARM: 8280/1: sa1100: switch to irq_domain_add_simple() ARM: 8279/1: sa1100: merge both GPIO irqdomains ARM: 8278/1: sa1100: split irq handling for low GPIOs ARM: 8291/1: replace magic number with PAGE_SHIFT macro in fixup_pv code ARM: 8290/1: decompressor: fix a wrong comment ARM: 8286/1: mm: Fix dma_contiguous_reserve comment ARM: 8248/1: pm: remove outdated comment ARM: 8274/1: Fix DEBUG_LL for multi-platform kernels (without PL01X) ARM: 8273/1: Seperate DEBUG_UART_PHYS from DEBUG_LL on EP93XX ...

+What:		/sys/bus/amba/devices/.../driver_override
+Date:		September 2014
+Contact:	Antonios Motakis <a.motakis@virtualopensystems.com>
+Description:
+		This file allows the driver for a device to be specified which
+		will override standard OF, ACPI, ID table, and name matching.
+		When specified, only a driver with a name matching the value
+		written to driver_override will have an opportunity to bind to
+		the device. The override is specified by writing a string to the
+		driver_override file (echo vfio-amba > driver_override)	and may
+		be cleared with an empty string (echo > driver_override).
+		This returns the device to standard matching rules binding.
+		Writing to driver_override does not automatically unbind the
+		device from its current driver or make any attempt to
+		automatically load the specified driver. If no driver with a
+		matching name is currently loaded in the kernel, the device will
+		not bind to any driver. This also allows devices to opt-out of
+		driver binding using a driver_override name such as "none".
+		Only a single driver may be specified in the override, there is
+		no support for parsing delimiters.
