Thanks Adrian. I don't have a pa-risc cross-compiler and there isn't one
at the usual source http://userweb.kernel.org/~akpm/cross-compilers but the
patch below should fix it. Note that this debugging code should be deleted if
the mm-initialisation-and-debugging framework in -mm is merged to mainline
as it knows how to print all the zonelists where as the pa-risc equivilant
misses the GFP_THISNODE lists.

=====
Subject: [PATCH] Fix pa-risc DISCONTIGMEM compile breakage
    
PA-RISC to aid debugging prints out the zonelists setup by the system. A
bad call to node_zonelist() breaks at compile-time. This patch fixes it.
