x86, nx: Don't force pages RW when setting NX bits Xen want page table pages read only. But the initial page table (from head_*.S) live in .data or .bss. That was broken by 64edc8ed5ffae999d8d413ba006850e9e34166cb. There is absolutely no reason to force these pages RW after they have already been marked RO.
