Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20180629' into staging
target-arm queue:
* last of the SVE patches; SVE is now enabled for aarch64 linux-user
* sd: Don't trace SDRequest crc field (coverity bugfix)
* target/arm: Mark PMINTENSET accesses as possibly doing IO
* clean up v7VE feature bit handling
* i.mx7d: minor cleanups
* target/arm: support reading of CNT[VCT|FRQ]_EL0 from user-space
* target/arm: Implement ARMv8.2-DotProd
* virt: add addresses to dt node names (which stops dtc from
complaining that they're not correctly named)
* cleanups: replace error_setg(&error_fatal) by error_report() + exit()
