2a05180fe2 x86, apic: move remaining APIC drivers to arch/x86/kernel/apic/*
Move the 32-bit extended-arch APIC drivers to arch/x86/kernel/apic/
too, and rename apic_64.c to probe_64.c.

f62bae5009 x86, apic: move APIC drivers to arch/x86/kernel/apic/*
arch/x86/kernel/ is getting a bit crowded, and the APIC
drivers are scattered into various different files.

Move them to arch/x86/kernel/apic/*, and also remove
the 'gen' prefix from those which had it.

Also move APIC related functionality: the IO-APIC driver,
the NMI and the IPI code.

be163a159b x86, apic: rename 'genapic' to 'apic'
Impact: cleanup

Now that all APIC code is consolidated there's nothing 'gen' about
apics anymore - so rename 'struct genapic' to 'struct apic'.

This shortens the code and is nicer to read as well.

d3185b37df x86, es7000: remove externs
Impact: cleanup

In the subarch times there were a number of externs between
various bits of the ES7000 code. Now that there's a single
es7000-platform support file, the externs can be removed and
the functions can be changed the statics.

Beyond the cleanup factor, this also shrinks the size of the
kernel image a bit:

b9e0d1aa97 x86, apic: remove apicid_cluster()
There were multiple definitions of apicid_cluster() scattered around
in APIC drivers - but the definitions are equivalent to the already
existing generic APIC_CLUSTER() method.

So remove apicid_cluster() and change all users to APIC_CLUSTER().

For those in the init namespace, while we're waiting to remove

14fa43f53f ASoC: Only register AC97 bus if it's not done already
ASoC supports both explicit codec drivers for AC97 devices and a simple
driver which uses the standard ALSA AC97 framework for codec support.
When used with the generic AC97 codec support that will provide the
ad hoc AC97 device for drivers like touchscreens to attach to so the
core shouldn't do so.
