Subject: x86: Increase CONFIG_NODES_SHIFT max to 10
X-Git-Tag: v2.6.34-rc4~27^2~1
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=51591e31dcb3716f03f962e26ec36a029aa46340;p=pandora-kernel.git

x86: Increase CONFIG_NODES_SHIFT max to 10

Some larger systems require more than 512 nodes, so increase the
maximum CONFIG_NODES_SHIFT to 10 for a new max of 1024 nodes.

This was tested with numa=fake=64M on systems with more than
64GB of RAM. A total of 1022 nodes were initialized.

Successfully builds with no additional warnings on x86_64
allyesconfig.

( No effect on any existing config. Newly enabled CONFIG_MAXSMP=y
  will see the new default. )
