socsvn commit: r237215 - soc2012/emc2/experimental

[emc2 at FreeBSD.org]

Author: emc2
Date: Wed Jun  6 14:10:47 2012
New Revision: 237215
URL: http://svnweb.FreeBSD.org/socsvn/?view=rev&rev=237215

Log:
  One problem solved (sort of).  It seems compiling with clang generates bad
  offsets for calls, for some reason.  Compiling with gcc fixes the problem.
  However, it's still hanging whenever I try to call EFI builtin functions,
  for some reason.
