New Revision: 268504
URL: http://svnweb.freebsd.org/changeset/base/268504
Log:
Correct the accounting code for wired mappings. The wrong field of the PVO
entry was being tested. We were incrementing and decrementing the pmap's
wired mapping count based on whether the physical page being mapped or
unmapped was cache coherent, not whether it was a wired mapping.
