Revision 0d01532451710110a93891ae152d1dd1ee006ccf authored by Daniel Yeisley on 30 May 2006, 20:47:57 UTC, committed by Linus Torvalds on 31 May 2006, 03:31:06 UTC 
[PATCH] x86_64: Handle empty node zero
 
From: Daniel Yeisley <dan.yeisley@unisys.com>

It is possible to boot a Unisys ES7000 with CPUs from multiple cells, and not
also include the memory from those cells.  This can create a scenario where
node 0 has cpus, but no associated memory.  The system will boot fine in a
configuration where node 0 has memory, but nodes 2 and 3 do not.

[AK: I rechecked the code and generic code seems to indeed handle that already.
Dan's original patch had a change for mm/slab.c that seems to be already in now.]
