Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20151016' into staging

target-arm queue:
 * break TBs after ISB instructions
 * more support code for future implementation of EL2 and 64-bit EL3
 * tell guest if KVM is enabled in SMBIOS version string
 * implement OSLAR/OSLSR system registers
 * provide better help text for Sharp PDA machine names
 * rename imx25_pdk to imx25-pdk (since it has never been released
   with the underscore-version name)
 * fix MMIO writes in zynq_slcr
 * implement MDCR_EL2
 * virt: allow the guest to configure PCI BARs with zero PCI addresses
 * fix breakpoint handling code
