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

| 1 | What: /sys/bus/amba/devices/.../driver_override | ||
| 2 | Date: September 2014 | ||
| 3 | Contact: Antonios Motakis <a.motakis@virtualopensystems.com> | ||
| 4 | Description: | ||
| 5 | This file allows the driver for a device to be specified which | ||
| 6 | will override standard OF, ACPI, ID table, and name matching. | ||
| 7 | When specified, only a driver with a name matching the value | ||
| 8 | written to driver_override will have an opportunity to bind to | ||
| 9 | the device. The override is specified by writing a string to the | ||
| 10 | driver_override file (echo vfio-amba > driver_override) and may | ||
| 11 | be cleared with an empty string (echo > driver_override). | ||
| 12 | This returns the device to standard matching rules binding. | ||
| 13 | Writing to driver_override does not automatically unbind the | ||
| 14 | device from its current driver or make any attempt to | ||
| 15 | automatically load the specified driver. If no driver with a | ||
| 16 | matching name is currently loaded in the kernel, the device will | ||
| 17 | not bind to any driver. This also allows devices to opt-out of | ||
| 18 | driver binding using a driver_override name such as "none". | ||
| 19 | Only a single driver may be specified in the override, there is | ||
| 20 | no support for parsing delimiters. | ||
