New Revision: 309017
URL: https://svnweb.freebsd.org/changeset/base/309017
Log:
Remove PG_CACHED-related fields from struct vmmeter, because they
are no
longer used. More precisely, they are always zero because the code
that
decremented and incremented them no longer exists.
Bump __FreeBSD_version to mark this change.

Removing these fields cause build failures, at least with MPC85XX/
MPC85XXSPE (see make universe), because it ends up changing the size
of struct pcpu.
