Sean Christopherson 3e3e8551a5 KVM: Play nice with read-only memslots when querying host page size ... [ Upstream commit 42cde48b2d39772dba47e680781a32a6c4b7dc33 ] Avoid the "writable" check in __gfn_to_hva_many(), which will always fail on read-only memslots due to gfn_to_hva() assuming writes. Functionally, this allows x86 to create large mappings for read-only memslots that are backed by HugeTLB mappings. Note, the changelog for commit 05da45583d ("KVM: MMU: large page support") states "If the largepage contains write-protected pages, a large pte is not used.", but "write-protected" refers to pages that are temporarily read-only, e.g. read-only memslots didn't even exist at the time.
