  • 1aabd67d2   ia64: Switch do_timer() to xtime_update() ... Browse Code »

    local_cpu_data->itm_next = new_itm; does not need to be protected by
    xtime_lock. xtime_update() takes the lock itself.

  • c6e22f9e3   percpu: make percpu symbols in xen unique ... Browse Code »

    This patch updates percpu related symbols in xen such that percpu
    symbols are unique and don't clash with local symbols. This serves
    two purposes of decreasing the possibility of global percpu symbol
    collision and allowing dropping per_cpu__ prefix from percpu symbols.

    * arch/x86/xen/smp.c, arch/x86/xen/time.c, arch/ia64/xen/irq_xen.c:
    add xen_ prefix to percpu variables

    * arch/ia64/xen/time.c: add xen_ prefix to percpu variables, drop
    processed_ prefix and make them static

    Partly based on Rusty Russell's "alloc_percpu: rename percpu vars
    which cause name clashes" patch.

  • a157229ca   rcu: Simplify rcu_pending()/rcu_check_callbacks() API ... Browse Code »

    All calls from outside RCU are of the form:

    if (rcu_pending(cpu))
    rcu_check_callbacks(cpu, user);

    This is silly, instead we put a call to rcu_pending() in
    rcu_check_callbacks(), and then make the outside calls be to
    rcu_check_callbacks(). This cuts down on the code a bit and
    also gives the compiler a better chance of optimizing.
