revision 1.179 to correctly set/clear execute permission on the mapping it creates. Thus, mmap(2)ing a memory resident file will not result in the file being mapped with execute permission when execute permission was not requested. Eliminate an unneeded Instruction Memory Barrier (IMB) in pmap_enter_quick(). Since there was no previous (instruction) mapping for the given virtual address prior to pmap_enter_quick(), there can be no instructions from the given virtual address in the pipeline that need flushing.
