Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20160512' into staging

target-arm queue:
 * blizzard, omap_lcdc: code cleanup to remove DEPTH != 32 dead code
 * QOMify various ARM devices
 * bcm2835_property: use cached values when querying framebuffer
 * hw/arm/nseries: don't allocate large sized array on the stack
 * fix LPAE descriptor address masking (only visible for EL2)
 * fix stage 2 exec permission handling for AArch32
 * first part of supporting syndrome info for data aborts to EL2
 * virt: NUMA support
 * work towards i.MX6 support
 * avoid unnecessary TLB flush on TCR_EL2, TCR_EL3 writes
