Tom Lendacky 0fc5deae03 KVM: SVM: Remove unneeded WBINVD and DF_FLUSH when starting SEV guests ... Performing a WBINVD and DF_FLUSH are expensive operations. The SEV support currently performs this WBINVD/DF_FLUSH combination when an SEV guest is terminated, so there is no need for it to be done before LAUNCH. However, when the SEV firmware transitions the platform from UNINIT state to INIT state, all ASIDs will be marked invalid across all threads. Therefore, as part of transitioning the platform to INIT state, perform a WBINVD/DF_FLUSH after a successful INIT in the PSP/SEV device driver. Since the PSP/SEV device driver is x86 only, it can reference and use the WBINVD related functions directly.
