Subject: [PATCH 02/31] cpumask: modify send_IPI_mask interface to accept cpumask_t pointers
Date: Monday, September 29, 2008 - 11:02 am

* Change genapic interfaces to accept cpumask_t pointers and to not
    return cpumask function values.

  * Modify external callers to use these cpumask_t pointers in their calls.

  * Create new send_IPI_mask_allbutself which is the same as the
    send_IPI_mask functions but removes smp_processor_id() from list.
    This removes another common need for a temporary cpumask_t variable.

  * Rewrite functions that used a temp cpumask_t variable for:

	cpumask_t allbutme = cpu_online_map;

	cpu_clear(smp_processor_id(), allbutme);
	if (!cpus_empty(allbutme))
		...

    It becomes:

	if (!cpus_equal(cpu_online_map, cpumask_of_cpu(cpu)))
		...

  * Other minor code optimizations.


Applies to linux-2.6.tip/master.
