Subject: [2.6.6-mm3] 1/3: merge std_resources.c back into setup.c
Date: Tue, 18 May 2004 01:38:34 +0200 [thread overview]
Message-ID: <40A94CFA.6070805@keyaccess.nl> (raw)

Hi Andrew.
std_resources.{c,h} was only split off due to pc9800 wanting to override
it. With it gone, it might as well be merged back in. Doesn't change any
code. It was compiled and booted.
This time this also actually doesn't break compilation of any of the
subarches. That's to say, any further. I guess it might have been my
.config (my regular PC config, with just the subarch switched through
menuconfig) or O=, but only ELAN actually compiled. Voyager and VISWS
bombed out at the final link and NUMAQ much sooner (with "physnode_map
undeclared" during compilation of numaq.c).
Rene.
