    SubjectCommit 34d76c41 causes linker errors on ia64 with NR_CPUS=4096
    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.
