Re: 2.6.0 test3 does not boot on ia64 NUMA

Martin,

Thanks for answering my mail. I applied Jesse's patch ([PATCH] latest
discontig mail dated Fri, 8 Aug 2003) but this does'nt build with:
	CONFIG_NUMA=y
	CONFIG_ACPI_NUMA=y
	CONFIG_DISCONTIGMEM=y
	# CONFIG_VIRTUAL_MEM_MAP is not set
I get:
include/linux/mm.h: In function `lowmem_page_address':
include/linux/mm.h:349: `mem_map' undeclared (first use in this function)

It seems that this only works on Altix, unless I missed something.

BTW, applying your patch for removing alloc_bootmem and moving back
find_memory() to its previous place, system boots OK.
Thanks again for your help.

Xavier
