This series (or rather the last patch of it) takes different approach to "rep ins" optimization. Instead of writing separate fast path for it do the fast path inside emulator itself. This way nobody can say the code is not reused! Patch 1,2 are now, strictly speaking, not needed, but I think this is still nice cleanup and, in case of patch 1, eliminates some ifs at each KVM_RUN ioctl. Gleb Natapov (4): Provide userspace IO exit completion callback.
