Hi, I had to apply the following two patches to get 2.6.3-mm1 to compile on ia64. I'm not sure if the pfn_to_nid() is correct. I used an extern to avoid a circular include of asm/numa.h and asm/mmzone.h I also reverted the compat-ipc-consolidation.patch patch because it didn't compile and I couldn't even find a trace of struct compat_ipc64_perm mh -- Martin Hicks Wild Open Source Inc. mort@wildopensource.com 613-266-2296
