Alan Cox e420c0cab7 Preset the modified bit in the PTE when pmap_enter() is called during a
write fault or while wiring a mapping that must support write access.

In general, this change should reduce the number of traps that occur for
the purpose of setting the modified bit.  More specifically, this change
should prevent traps while holding locks in a sysctl handler.  See
kern/kern_sysctl.c revisions 1.168 and 1.195 (svn r192160) for further
details.
