svn commit: r210911 - head/sys/mips/sibyte

[Neel Natu]

Author: neel
Date: Fri Aug  6 05:30:55 2010
New Revision: 210911
URL: http://svn.freebsd.org/changeset/base/210911

Log:
  Use a signed integer to hold the address of a register.
  
  This does the right thing by sign extending the address when compiling for
  the n64 abi.
