Using\natomic operations to do this is fine for all hypervisors I am aware of.\nHowever, for hypervisors which shadow page tables, if these PTE\nmodifications are not trapped, you need a post-modification call to fulfill\nthe update of the shadow page table.\n\nAcked-by: Zachary Amsden \u003czach@vmware.com\u003e\nCc: Hugh Dickins \u003chugh@veritas.com\u003e\nSigned-off-by: David Rientjes \u003crientjes@google.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
