  commit b56a0cdeaf91347a2c738dc5dd0350420e0e7201
  Author: Jan Beulich <jbeulich@xxxxxxxx>
  Date:   Tue Mar 6 16:24:41 2018 +0100
  
      x86/HVM: don't give the wrong impression of WRMSR succeeding
      
      ... for non-existent MSRs: wrmsr_hypervisor_regs()'s comment clearly
      says that the function returns 0 for unrecognized MSRs, so
      {svm,vmx}_msr_write_intercept() should not convert this into success. We
      don't want to unconditionally fail the access though, as we can't be
      certain the list of handled MSRs is complete enough for the guest types
      we care about, so instead mirror what we do on the read paths and probe
      the MSR to decide whether to raise #GP.
