But better late than never, I guess. From v1: - fix buglets (thanks Gavin) - add patch 3 on top The kvm_{get,set}_one_reg functions have been around for a very long time, and using them instead of open-coding the ioctl invocations saves lines of code, and gives us a tracepoint as well. They cannot be used by invocations of the ioctl not acting on a CPUState, but that still leaves a lot of conversions in the target/arm code. target/mips and target/ppc also have some potential for conversions, but as I cannot test either (and they are both in 'Odd fixes' anyway), I left them alone. Survives some testing on a Mt. Snow.
