  Modified:    sys/i386/i386  trap.c
               sys/miscfs/procfs  procfs_mem.c
               sys/vm    vm_fault.c vm_map.c vm_map.h vm_prot.h
  Log:
  Fix the gdb executable modify problem.  Thanks to the detective work
  by Alan Cox <alc@cs.rice.edu>, and his description of the problem.
  
  The bug was primarily in procfs_mem, but the mistake likely happened
  due to the lack of vm system support for the operation.  I added
  better support for selective marking of page dirty flags so that
  vm_map_pageable(wiring) will not cause this problem again.
  
  The code in procfs_mem is now less bogus (but maybe still a little
  so.)
