Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20170904-2' into staging

target-arm:
 * collection of M profile cleanups and minor bugfixes
 * loader: handle ELF files with overlapping zero-init data
 * virt: allow PMU instantiation with userspace irqchip
 * wdt_aspeed: Add support for the reset width register
 * cpu: Define new cpu_transaction_failed() hook
 * Mark some SoC devices as not user-creatable
 * arm: Fix aa64 ldp register writeback
 * arm_gicv3_kvm: Fix compile warning
