[1/1] KVM: VMX: Modify the BUILD_BUG_ON_MSG of the 32-bit field in the vmcs_check16 function https://github.com/kvm-x86/linux/commit/caf22c6dd312 -- https://github.com/kvm-x86/linux/tree/next

According to the SDM, the meaning of field bit 0 is: Access type (0 = full; 1 = high); must be full for 16-bit, 32-bit, and natural-width fields. So there is no 32-bit high field here, it should be a 32-bit field instead.
