Re: 32bit panic on 4 sockets

Re: 32bit panic on 4 sockets

[Yinghai Lu]

linus tree is broken too, it is one 4 sockets system and every sockets
hold 2g ram...
other system with more than 4g on every socket, works well.
maybe it never work...

Seems a bit daft to run a 32bit kernel on such a machine.. at some point
we should just give up and not push this 32 bit madness any further.

it works just fine on a lot of systems - and since we keep 
unifying a lot of these codepaths we are better off keeping it 
all working.

Sure, but eg. running with 16GB on a 32bit system just isn't going to
work well. Same with large cpu-count, at some point you might be able to
boot, but not much else.
