x86: fix cpu_mask_to_apicid_and to include cpu_online_mask
Impact: fix potential APIC crash
In determining the destination apicid, there are usually three cpumasks
that are considered: the incoming cpumask arg, cfg->domain and the
cpu_online_mask. Since we are just introducing the cpu_mask_to_apicid_and
function, make sure it includes the cpu_online_mask in it's evaluation.
[Added with this patch.]
There are two io_apic.c functions that did not previously use the
cpu_online_mask: setup_IO_APIC_irq and msi_compose_msg. Both of these
simply used cpu_mask_to_apicid(cfg->domain & TARGET_CPUS), and all but
one arch (NUMAQ[*]) returns only online cpus in the TARGET_CPUS mask,
so the behavior is identical for all cases.
[*: NUMAQ bug?]
Note that alloc_cpumask_var is only used for the 32-bit cases where
it's highly likely that the cpumask set size will be small and therefore
CPUMASK_OFFSTACK=n. But if that's not the case, failing the allocate
will cause the same return value as the default.

I happened to notice that the ibmphp hotplug driver does something
rather silly in its init routine. It purposely calls module_put so as
to underflow its module ref count to avoid being removed from the
kernel. This is bad practice, and wrong, since it provides a window for
subsequent module_gets to reset the refcount to zero, allowing an unload
to race in and cause all sorts of mysterious panics. If the module is
unsafe to load, simply omitting the module_exit parameter is sufficient
to prevent the kernel from allowing the unload.

Originally designed by Intel, now sold by Crossbow (www.xbow.com).
Very little actually on board. The patch includes sensors and
similar as found on commonly occurring daughter boards.
Some of the drivers are not in mainline as yet as they are either
part of the IIO subsystem or need a lot of work before submission.
What is the position wrt to putting them in i2c board configs etc?
Support for these boards has been maintained outside the kernel
for a long time, but now that there is a good da9030 pmic driver
available the last major hurdle no longer exists.
All comments welcomed.
The Imote2's big brother (stargate2) will follow once any problems
with this one have been cleaned up and a few bits and bobs have
been added to the da903x driver. Hopefully the cc2420 driver will
get cleaned up and submitted in the not too distant future as
well.
