 Log Message:
 PR/60522: evbppc/RB800 hits MI pmap KASSERT failure
 
 Revert the pmap_protect part of
 
     Fix two EXECness issues
     - when creating a WX mapping via pmap_enter mark the page as EXEC
     - when pmap_protect adds X then ensure that pmap_page_syncicache is called
       for the page.
 
 It seems that pmap_pte_protect is designed to remove a protection and not
 add it.
 
 For the module loading the text is indeed mapped eXecute initially, and
 cache maintenance is currently handled by kobj_machdep and not the pmap.
