Patch #1 fixes a bunch of issues I spotted in the acrn driver. It compiles, that's all I know. I'll appreciate some review and testing from acrn folks. Patch #2+#3 improve follow_pte(), passing a VMA instead of the MM, adding more sanity checks, and improving the documentation. Gave it a quick test on x86-64 using VM_PAT that ends up using follow_pte(). Not CCing all s390x and x86 maintainers (but lists), to reduce noise. As this depends on other stuff in mm-unstable, this should likely go via the MM tree.
