commit 1a2142afa5646ad5af44bbe1febaa5e0b7e71156
Author: Rusty Russell <rusty@xxxxxxxxxxxxxxx>
Date: Mon Mar 30 22:05:10 2009 -0600

cpumask: remove dangerous CPU_MASK_ALL_PTR, &CPU_MASK_ALL

Impact: cleanup

(Thanks to Al Viro for reminding me of this, via Ingo)

CPU_MASK_ALL is the (deprecated) "all bits set" cpumask, defined as so:

#define CPU_MASK_ALL (cpumask_t) { { ... } }

Taking the address of such a temporary is questionable at best,
unfortunately 321a8e9d (cpumask: add CPU_MASK_ALL_PTR macro) added
CPU_MASK_ALL_PTR:

#define CPU_MASK_ALL_PTR (&CPU_MASK_ALL)

Which formalizes this practice. One day gcc could bite us over this
usage (though we seem to have gotten away with it so far).

So replace everywhere which used &CPU_MASK_ALL or CPU_MASK_ALL_PTR
with the modern "cpu_all_mask" (a real const struct cpumask *).

cpumask: fix seq_bitmap_*() functions.

1) seq_bitmap_list() should take a const.
2) All the seq_bitmap should use cpumask_bits().

cpumask: remove node_to_first_cpu

Everyone defines it, and only one person uses it
(arch/mips/sgi-ip27/ip27-nmi.c). So just open code it there.

cpumask: use set_cpu_active in init/main.c

cpu_active_map is deprecated in favor of cpu_active_mask, which is
const for safety: we use accessors now (set_cpu_active) is we really
want to make a change.

cpumask: use mm_cpumask() wrapper: kernel/fork.c

Impact: futureproof

Makes code futureproof against the impending change to mm->cpu_vm_mask.

It's also a chance to use the new cpumask_ ops which take a pointer.

cpumask: remove references to struct irqaction's mask field.

Impact: cleanup

It's unused, since about 1995. So remove all initialization of it in
preparation for actually removing the field.
