X-Git-Tag: v2.6.18-rc1~581
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=10ad400b49aca15ecf83b0fde7e35e4064b15c85;p=pandora-kernel.git

[PATCH] pgdat allocation for new node add (refresh node_data[])

Refresh NODE_DATA() for generic archs.  In this case, NODE_DATA(nid) ==
node_data[nid].  node_data[] is array of address of pgdat.  So, refresh is
quite simple.
