Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20150626' into staging

target-arm queue:
 * Change the virt board's default interface type for block devices to virtio
 * Improve some error messages that will now be triggered by some incorrect
   but previously worked-by-accident command lines
 * Print ELR if we're doing debug logging of AArch64 exception entry
 * Handle the "completely empty semihosting commandline" correctly for
   softmmu (we already did for linux-user)
 * Add GICv2m description to ACPI tables for virt board
 * Fix some incorrect table revision entries in virt board ACPI tables
