Merge branch 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm
Pull ARM updates from Russell King: "Bigger items included in this update are: - A series of updates from Arnd for ARM randconfig build failures - Updates from Dmitry for StrongARM SA-1100 to move IRQ handling to drivers/irqchip/ - Move ARMs SP804 timer to drivers/clocksource/ - Perf updates from Mark Rutland in preparation to move the ARM perf code into drivers/ so it can be shared with ARM64. - MCPM updates from Nicolas - Add support for taking platform serial number from DT - Re-implement Keystone2 physical address space switch to conform to architecture requirements - Clean up ARMv7 LPAE code, which goes in hand with the Keystone2 changes. - L2C cleanups to avoid unlocking caches if we're prevented by the secure support to unlock. - Avoid cleaning a potentially dirty cache containing stale data on CPU initialisation - Add ARM-only entry point for secondary startup (for machines that can only call into a Thumb kernel in ARM mode). Same thing is also done for the resume entry point. - Provide arch_irqs_disabled via asm-generic - Enlarge ARMv7M vector table - Always use BFD linker for VDSO, as gold doesn't accept some of the options we need. - Fix an incorrect BSYM (for Thumb symbols) usage, and convert all BSYM compiler macros to a "badr" (for branch address). - Shut up compiler warnings provoked by our cmpxchg() implementation. - Ensure bad xchg sizes fail to link" * 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm: (75 commits) ARM: Fix build if CLKDEV_LOOKUP is not configured ARM: fix new BSYM() usage introduced via for-arm-soc branch ARM: 8383/1: nommu: avoid deprecated source register on mov ARM: 8391/1: l2c: add options to overwrite prefetching behavior ARM: 8390/1: irqflags: Get arch_irqs_disabled from asm-generic ARM: 8387/1: arm/mm/dma-mapping.c: Add arm_coherent_dma_mmap ARM: 8388/1: tcm: Don't crash when TCM banks are protected by TrustZone ARM: 8384/1: VDSO: force use of BFD linker ARM: 8385/1: VDSO: group link options ARM: cmpxchg: avoid warnings from macro-ized cmpxchg() implementations ARM: remove __bad_xchg definition ARM: 8369/1: ARMv7M: define size of vector table for Vybrid ARM: 8382/1: clocksource: make ARM_TIMER_SP804 depend on GENERIC_SCHED_CLOCK ARM: 8366/1: move Dual-Timer SP804 driver to drivers/clocksource ARM: 8365/1: introduce sp804_timer_disable and remove arm_timer.h inclusion ARM: 8364/1: fix BE32 module loading ARM: 8360/1: add secondary_startup_arm prototype in header file ARM: 8359/1: correct secondary_startup_arm mode ARM: proc-v7: sanitise and document registers around errata ARM: proc-v7: clean up MIDR access ...
