Hi all,
There is currently a check that the ramdisk image resides at a sane
memory address, below "max_pfn". However, max_pfn isn't initialized
(and apparently isn't relevant) for ip27. The only assignments to
max_pfn lie inside #ifndef CONFIG_SGI_IP27.
Therefore, this test is bogus, so here's a patch to
#ifndef CONFIG_SGI_IP27 it.
This patch applies cleanly on 2.4.x and 2.5.x (at a different offset).
Cheers,
Andrew
