The next .36 stable or something else? 5b5c1af104ab5 fixed an issue exposed by b40827fa7268. I'm not sure if fd89a13792 also exposes a similar issue, but I think it does not: It looks to me like fd89a13792 only reads from swapper_pg_dir and writes to trampoline_pg_dir which is unpinned (and unused) under Xen and hence there is no problem and 5b5c1af104ab5 is not needed. b40827fa7268 is in 2.6.37-rc and doesn't seem to be targeted for a stable backport AFAICT.
