While writing a selftest for the feature, I've discovered an embarassing
bug: in nested_svm_vmrun_msrpm() I check bit number instead of bit
mask. It worked in testing by pure luck, it seems genuine Hyper-V sets
some other clean fields simultaneously.
Would it be possible to squash the attached patch in? Thanks!
I'll be sending out selftests shortly.
