Subject: KVM: VMX: Avoid duplicate ept tlb flush when setting cr3
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=2d84e993a8947dbeb6b416555940d97522330846;p=linux-beck.git

KVM: VMX: Avoid duplicate ept tlb flush when setting cr3

vmx_set_cr3() will call vmx_tlb_flush(), which will flush the ept context.
So there is no need to call ept_sync_context() explicitly.
