s/same/inverse/?

Also the ordering issue extends to other calls, and I think if at all
possible we should then do all the teardown in reverse order of
init.

But it would also be good to CC the Intel VMX maintainers in case they
spot something in vmx_vcpu_destroy.

[Xen-devel] [RFC PATCH 3/9] x86/HVM: Call vlapic_destroy after vcpu_destroy

2016-09-18 Thread Suravee Suthikulpanit
