2019-01-24target/mips: Correct the second argument type of cpu_supports_isa()Aleksandar Markovic
"insn_flags" bitfield was expanded from 32-bit to 64-bit in commit f9c9cd63e3. However, this was not reflected on the second argument of the function cpu_supports_isa(). By chance, this did not create some wrong behavior, since the left-most halves of all instances of the second argument are currently all zeros. However, this is still a bug waiting to happen. Correct this by changing the type of the second argument to be always 64-bit. Reviewed-by: Philippe Mathieu-Daudé <philmd@redhat.com> Signed-off-by: Aleksandar Markovic <amarkovic@wavecomp.com>

2019-01-22target/microblaze: Switch to transaction_failed hookPeter Maydell
Switch the microblaze target from the old unassigned_access hook to the transaction_failed hook. The notable difference is that rather than it being called for all physical memory accesses which fail (including those made by DMA devices or by the gdbstub), it is only called for those made by the CPU via its MMU. For microblaze this makes no difference because none of the target CPU code needs to make loads or stores by physical address.

2019-01-21target/arm: Swap PMU values before/after migrationsAaron Lindsay
Because of the PMU's design, many register accesses have side effects which are inter-related, meaning that the normal method of saving CP registers can result in inconsistent state. These side-effects are largely handled in pmu_op_start/finish functions which can be called before and after the state is saved/restored. By doing this and adding raw read/write functions for the affected registers, we avoid migration-related inconsistencies.

2019-01-21target/arm: Reorganize PMCCNTR accessesAaron Lindsay
pmccntr_read and pmccntr_write contained duplicate code that was already being handled by pmccntr_sync. Consolidate the duplicated code into two functions: pmccntr_op_start and pmccntr_op_finish. Add a companion to c15_ccnt in CPUARMState so that we can simultaneously save both the architectural register value and the last underlying cycle count - this ensures time isn't lost and will also allow us to access the 'old' architectural register value in order to detect overflows in later patches.
