Perhaps Peter knows ? dhowells: hey, I know you don't care about FRV anymore, but suppose the 0-day thing says things like: >> frv-linux-ld: Warning: size of symbol `sys_setuid' changed from 272 in >> kernel/sys.o to 8 in kernel/sys_ni.o dhowells: do you have any clue wth went wrong? peterz: it's been saying that for a long time, but I've no idea why didn't seem to stop it working I suspect it might not be handing weak symbol elimination correctly or something fair enough, I'll ignore it then
