  Log:
   - Correct a long-standing race condition in vm_page_try_to_cache() that
     could result in a panic "vm_page_cache: caching a dirty page, ...":
     Access to the page must be restricted or removed before calling
     vm_page_cache().  This race condition is identical in nature to that
     which was addressed by vm_pageout.c's revision 1.251.
   - Simplify the code surrounding the fix to this same race condition
     in vm_pageout.c's revision 1.251.  There should be no behavioral
     change.  Reviewed by: tegge
