Hi Peter -
Commit 34d76c41 introduced the update_shares_data percpu, but it ends up causing problems on large ia64 machines. Specifically, ia64 is limited to 64k in percpu vars and with NR_CPUS=4096, that ends up being 32k by itself. It ends up causing link errors since that is how ia64 enforces the 64k limit.
I can take a deeper look at finding a workable solution but thought I'd mention it in case you had ideas already.
