svn commit: r207130 - head/sys/mips/mips

[Juli Mallett]

Author: jmallett
Date: Fri Apr 23 18:53:17 2010
New Revision: 207130
URL: http://svn.freebsd.org/changeset/base/207130

Log:
  Large memory mappings are always CPU local and always done with interrupts
  disabled.  Be doubly-sure that we don't try to do a TLB shootdown on SMP
  systems for those mappings.
