Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20161024' into staging

target-arm queue:
 * support variable (runtime-determined) page sizes, for a
   nearly-20% speedup of TCG for ARMv7 and v8 CPUs with 4K pages
 * ptimer: add tests, support more flexible behaviour around
   what happens on the "zero" tick, use ptimer for a9gtimer
 * virt: ACPI: Add IORT Structure definition
 * i2c: Fix SMBus read transactions to avoid double events
 * timer: stm32f2xx_timer: add check for prescaler value
 * QOMify musicpal, pxa2xx_gpio, strongarm, pl110
 * target-arm: Implement new HLT trap for semihosting
 * i2c: Add asserts for second smbus i2c_start_transfer()
