While the code looks nicer with the second patch, the fact that get_rflags() does a vmcs_read() seems 7 times more than before seems unfortunate.
We can add kvm_rflags_read(), see kvm_cache_regs.h. In any case, it's purely academic since task switches are rare and incredibly slow anyway (you have to vmcs_write() the entire register set for one).
