Author: jeff

New revision: 327485
URL: https://svnweb.freebsd.org/changeset/base/327485

Log:
  Fix arc after r326347 broke various memory limit queries.  Use UMA featur=
es
  rather than kmem arena size to determine available memory.

  Initialize the UMA limit to LONG_MAX to avoid spurious wakeups on boot be=
fore
  the real limit is set.
