Re: vmlinux-sun3.lds (was: Re: Kernel 2.6 for m68k/amiga)
The patch "looks" ok to me, though I don't have access to a real sun3 from
work (well, that's not true, sammy.net is here, but I hardly want to
reboot it to test).
If it compiles, go ahead and throw it in, and I'll keep it in mind for
whenever I get enough free time to actually update sun3 to modern 2.6.
