svn commit: r243430 - projects/counters/sys/vm

[Gleb Smirnoff]

Author: glebius
Date: Fri Nov 23 07:06:24 2012
New Revision: 243430
URL: http://svnweb.freebsd.org/changeset/base/243430

Log:
  Right now PAGE_SIZE == UMA_SLAB_SIZE, but that can change in future.
  
  Use PAGE_SIZE when we are multiplying pages or uk_ppera. The change is
  a nop, but makes code consistent.
