Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20180410' into staging
target-arm queue:
* fpu: Fix rounding mode for floatN_to_uintM_round_to_zero
* tcg: Fix guest state corruption when running 64-bit Arm
guests on a 32-bit host (especially when using icount)
* linux-user/signal.c: Ensure AArch64 signal frame isn't too small
* cpus.c: ensure running CPU recalculates icount deadlines on timer expiry
* target/arm: Report unsupported MPU region sizes more clearly
* hw/arm/fsl-imx: Fix introspection problem with fsl-imx6 and fsl-imx7
* hw/arm/allwinner-a10: Do not use nd_table in instance_init function
* hw/sd/bcm2835_sdhost: Don't raise spurious interrupts
* hw/sd/bcm2835_sdhost: Add tracepoints
* target-arm: Check undefined opcodes for SWP in A32 decoder
* hw/arm/integratorcp: Don't do things that could be fatal in the instance_init
* hw/arm: Allow manually specified /psci node
