Modified Files:
        src/sys/arch/hppa/hppa: pmap.c

Log Message:
Convert pmap_check_alias into a function that resolves any aliases issues
to deal with the locking around entering a mapping of the same page with
and alias issue in the same pmap (pmap lock already held in pmap_enter)

This has the added benefit of only flushing the troublesome mappings.

The locking could be simplified further here and an PV list iterator
function with callback is probably useful.
