New Revision: 254533
URL: http://svnweb.freebsd.org/changeset/base/254533
Log:
Fix ARMv6/v7 mapping's wired status.
Last input argument in pmap_modify_pv() should be a mask of flags to be set.
In pmap_change_wiring() however, the straight wired status was used, which
does not represent valid flags (and is of type boolean).
This commit fixes the issue so that wired flag is passed to pmap_modify_pv()
properly.
