New Revision: 199729
URL: http://svn.freebsd.org/changeset/base/199729
Log:
MFC r198338:
o Align function on a 32-byte boundary so that the core's front-end
can deliver 2 bundles per cycle to the back-end.
o Mark syscall stubs with a special unwind ABI tag so that unwind
libraries know how to unwind.
