[IA64] Delete __cpuinit usage from all ia64 users

2013-06-24T22:44:27+00:00

The __cpuinit type of throwaway sections might have made sense
some time ago when RAM was more constrained, but now the savings
do not offset the cost and complications.  For example, the fix in
commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time")
is a good example of the nasty type of bugs that can be created
with improper use of the various __init prefixes.

After a discussion on LKML[1] it was decided that cpuinit should go
the way of devinit and be phased out.  Once all the users are gone,
we can then finally remove the macros themselves from linux/init.h.

This removes all the ia64 uses of the __cpuinit macros.

IA64: drivers: remove __dev* attributes.

2013-01-03T23:57:13+00:00

CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

ia64: SMP: Remove call to ipi_call_lock_irq()/ipi_call_unlock_irq()

2012-06-05T15:27:13+00:00

ipi_call_lock/unlock() lock resp. unlock call_function.lock. This lock
protects only the call_function data structure itself, but it's
completely unrelated to cpu_online_mask. The mask to which the IPIs
are sent is calculated before call_function.lock is taken in
smp_call_function_many(), so the locking around set_cpu_online() is
pointless and can be removed.

arch/ia64: remove references to cpu_*_map

2012-03-29T00:14:36+00:00

This was marked as obsolete for quite a while now..  Now it is time to
remove it altogether.  And while doing this, get rid of first_cpu() as
well.  Also, remove the redundant setting of cpu_online_mask in
smp_prepare_cpus() because the generic code would have already set cpu 0
in cpu_online_mask.
