* 'fixes' of master.kernel.org:/home/rmk/linux-2.6-arm: ARM: 6879/1: fix personality test wrt usage of domain handlers ARM: 6878/1: fix personality flag propagation across an exec ARM: 6877/1: the ADDR_NO_RANDOMIZE personality flag should be honored with mmap() ARM: 6876/1: Kconfig.debug: Remove unused CONFIG_DEBUG_ERRORS ARM: pxa: convert incorrect IRQ_TO_IRQ() to irq_to_gpio() ARM: mmp: align NR_BUILTIN_GPIO with gpio interrupt number ARM: pxa: align NR_BUILTIN_GPIO with GPIO interrupt number ARM: pxa: always clear LPM bits for PXA168 MFPR pcmcia: limit pxa2xx_trizeps4 subdriver to trizeps4 platform pcmcia: limit pxa2xx_balloon3 subdriver to balloon3 platform ARM: pxafb: Fix access to nonexistent member of pxafb_info ARM: 6872/1: arch:common:Makefile Remove unused config in the Makefile. ARM: 6868/1: Preserve the VFP state during fork ARM: 6867/1: Introduce THREAD_NOTIFY_COPY for copy_thread() hooks ARM: 6866/1: Do not restrict HIGHPTE to !OUTER_CACHE ARM: 6865/1: perf: ensure pass through zero is counted on overflow ARM: 6864/1: hw_breakpoint: clear DBGVCR out of reset ARM: Only allow PM_SLEEP with CPUs which support suspend ARM: Make consolidated PM sleep code depend on PM_SLEEP

information is useful to kernel hackers when tracking down problems,
