Sean Christopherson 8a42dc4fa5 KVM: Do not incorporate page offset into gfn=>pfn cache user address ... commit 3ba2c95ea1 upstream. Don't adjust the userspace address in the gfn=>pfn cache by the page offset from the gpa. KVM should never use the user address directly, and all KVM operations that translate a user address to something else require the user address to be page aligned. Ignoring the offset will allow the cache to reuse a gfn=>hva translation in the unlikely event that the page offset of the gpa changes, but the gfn does not. And more importantly, not having to (un)adjust the user address will simplify a future bug fix.
