You're right when there is no other proper header for a MSR field definition. While the Linux code is maintained in the manner of "divide and conquer", thus I would say the VMX fields definitions belong to the KVM community, and fortunately, there is such a vmx header. BTW, It looks to me that some perf MSRs and fields are not in msr-index.h, which avoids bothering the tip maintainers all the time. Thanks! Xin
