Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20150615' into staging

target-arm queue:
 * Handle "extended small page" descriptors correctly
 * Use extended address bits from supersection short descriptors
 * Update interrupt status for all cores in gic_update
 * Fix off-by-one in exynos4210_fimd bit-swap code
 * Remove stray unused 'pending_exception' field
 * Add Cortex-A53 KVM support
 * Fix reset value of REVIDR
 * Add AArch32 MIDR aliases for ARMv8 cores
 * MAINTAINERS update for ARM ACPI code
 * Trust the kernel's value of MPIDR if we're using KVM
 * Various pxa2xx device updates to avoid old APIs
 * Mark pxa2xx copro registers as ARM_CP_IO so -icount works
 * Correctly UNDEF Thumb2 DSP insns on Cortex-M3
 * Initial work towards implementing PMSAv7
 * Fix a reset order bug introduced recently
 * Correct "preferred return address" for cpreg access exceptions
 * Add ACPI SPCR table for the virt board
