Subject: uml: correct removal of pte_mkexec
From: Paolo 'Blaisorblade' Giarrusso <blaisorblade@xxxxxxxx>
Correct commit 5906e4171ad61ce68de95e51b773146707671f80 - this makes more
sense: we turn pte_mkexec + pte_wrprotect to pte_mkread. However, due to a
bug in pte_mkread, it does the exact same thing as pte_mkwrite, so this patch
improves the code but does not change anything in practice. The pte_mkread
bug is fixed separately, as it may have big impact.
