[ewg] Re: [ofa-general] ofed autoconf.h

[Steve Wise]

Attached is my final solution that resolves 1538 and 1578.  With this 
patch, the generated autoconf.h will have slightly different content 
based on whether __OFED__BUILD__ is defined.  I've added this define to 
the ofed makefile so it is defined when building the ofed kernel 
internally.  External modules including the ofed autoconf.h must _not_ 
define __OFED_BUILD__.

Semantically, here are the differences:

With __OFED_BUILD__ defined:

- #undef all ofed CONFIG defines
- #define only the ofed CONFIG defines enabled by the ofa kernel tree 
configuration

Without __OFED_BUILD__ defined:

- #include_next <linux/autoconf.h> first to get the backing kernel 
CONFIG defines
- #define only the CONFIG defines enabled by the ofa kernel tree 
configuration

Comments?

If nobody barks, I'll push this up to my git tree for Vlad to pull tomorrow.

Steve.
