Here is a patch for i386, sparc and sparc64. I tested it out
for i386 and it appears to work okay, no clue about sparc and sparc64
but I expect they will work as well. I tested it out w/ 'make config',
but I believe it will work with 'make menuconfig' and 'make xconfig',
but I'm not sure and would like to hear from folks on if it does/does
not work.
I went ahead and cc'ed the maintainers of SMP, SPARC and
MenuConfig, I couldn't find any other relevant maintainers to cc.
Again, this is NOT well-tested, I would request that people
test it out and get back to me if it does/doesn't work so I can fix
any bugs in it.
I'd like to know about other architectures and if they support
SMP or not, if not I can easily enough set this up to make sure
'#SMP = 0' in the Makefile, if so I will gladly update those config.in
files w/ this patch, please let me know.
