[Xen-devel] [PATCH] VMX: don't bypass vmx_update_secondary_exec_control()

["Jan Beulich" <JBeulich@xxxxxxxx>]

While putting together another patch modifying the secondary exec
controls I noticed that vmx_vcpu_update_vmfunc_ve() does a raw VMWRITE
instead of going through the designated function. I assume that is not
how it should be.
