[PATCH 0 of 4] mm+paravirt+xen: add pte read-modify-write abstraction (take 2)
Hi all,
[ Change since last post: change name to ptep_modify_prot_, on the
grounds that it isn't really a general pte-modification interface. ]
This little series adds a new transaction-like abstraction for doing
RMW updates to a pte, hooks it into paravirt_ops, and then makes use
of it in Xen.
The basic problem is that mprotect is very slow under Xen (up to 50x
slower than native),
