Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20151103' into staging

target-arm queue:
 * code cleanup to use symbolic constants for register bank numbers
 * fix direct booting of modern Linux kernels on xilinx_zynq by setting
   SCLR values to what the kernel expects firmware to have done
 * implement SYSRESETREQ for ARMv7M CPU (stellaris boards)
 * update MAINTAINERS to mention new qemu-arm mailing list
 * clean up display of PSTATE in AArch64 debug logs
 * report Secure/Nonsecure status in CPU debug logs
 * fix a missing _CCA attribute in ACPI tables
 * add support for GICv3 to ACPI tables
