svn commit: r210605 - head/sys/mips/include

[Jayachandran C.]

Author: jchandra
Date: Thu Jul 29 13:52:46 2010
New Revision: 210605
URL: http://svn.freebsd.org/changeset/base/210605

Log:
  Fix RQB_FFS for 64 bit, we need to use ffsl() for 64bit.
  
  Use 'ifdef __mips_n64' instead of 'if defined' to be consistant with other
  usage.
