Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20140310' into staging
target-arm queue:
* implement WFE as yield (improves performance with emulated SMP)
* fixes to avoid undefined behaviour shifting left into sign bit
* libvixl format string fixes for 32 bit hosts
* fix build error when intptr_t and tcg_target_long are different
sizes (eg x32)
* implement PMCCNTR register
* fix incorrect setting of E bit in CPSR (broke booting under
KVM on ARM)
