Subject[PATCH] ia64 support for tools/perf/
Date
Compiler on ia64 rejects the "-m64" option.
Add arch specific pieces to perf.h

Signed-off-by: Tony Luck <tony.luck@intel.com>

I expect there is a more elegant solution to the Makefile issue. Feel
free to throw away that part of this patch and replace it with something
prettier :-)
