Implement the protection check required by the pmap_extract_and_hold() specification. Remove the acquisition and release of Giant from pmap_extract_and_hold() and pmap_protect(). Many thanks to Ken Smith for resolving a sparc64-specific initialization problem in my original patch. Tested by: kensmith@ END
