Alan Cox e4ed417a35 Correct an error in vm_fault_copy_entry() that has existed since the first 
version of this file.  When a process forks, any wired pages are immediately
copied because copy-on-write is not supported for wired pages.  In other
words, the child process is given its own private copy of each wired page
from its parent's address space.  Unfortunately, to date, these copied pages
have been mapped into the child's address space with the wrong permissions,
typically VM_PROT_ALL.  This change corrects the permissions.
