Merge branch 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm
Pull ARM updates from Russell King: "The major updates included in this update are: - Clang compatible stack pointer accesses by Behan Webster. - SA11x0 updates from Dmitry Eremin-Solenikov. - kgdb handling of breakpoints with read-only text/modules - Support for Privileged-no-execute feature on ARMv7 to prevent userspace code execution by the kernel. - AMBA primecell bus handling of irq-safe runtime PM - Unwinding support for memset/memzero/memmove/memcpy functions - VFP fixes for Krait CPUs and improvements in detecting the VFP architecture - A number of code cleanups (using pr_*, removing or reducing the severity of a couple of kernel messages, splitting ftrace asm code out to a separate file, etc.) - Add machine name to stack dump output" * 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm: (62 commits) ARM: 8247/2: pcmcia: sa1100: make use of device clock ARM: 8246/2: pcmcia: sa1111: provide device clock ARM: 8245/1: pcmcia: soc-common: enable/disable socket clocks ARM: 8244/1: fbdev: sa1100fb: make use of device clock ARM: 8243/1: sa1100: add a clock alias for sa1111 pcmcia device ARM: 8242/1: sa1100: add cpu clock ARM: 8221/1: PJ4: allow building in Thumb-2 mode ARM: 8234/1: sa1100: reorder IRQ handling code ARM: 8233/1: sa1100: switch to hwirq usage ARM: 8232/1: sa1100: merge GPIO multiplexer IRQ to "normal" irq domain ARM: 8231/1: sa1100: introduce irqdomains support ARM: 8230/1: sa1100: shift IRQs by one ARM: 8229/1: sa1100: replace irq numbers with names in irq driver ARM: 8228/1: sa1100: drop entry-macro.S ARM: 8227/1: sa1100: switch to MULTI_IRQ_HANDLER ARM: 8241/1: Update processor_modes for hyp and monitor mode ARM: 8240/1: MCPM: document mcpm_sync_init() ARM: 8239/1: Introduce {set,clear}_pte_bit ARM: 8238/1: mm: Refine set_memory_* functions ARM: 8237/1: fix flush_pfn_alias ...
