Impact: cleanup
Clean up all the target_cpus() namespace overlap that exists
between bigsmp, es7000, mach-default, numaq and summit - by
separating the different functions into different names.

Impact: cleanup
They were only used in a single place and obscured the apic_es7000
driver template.

Remove the wrapper macros IRQ_DEST_MODE and IRQ_DELIVERY_MODE.
The typical 32-bit and the 64-bit build all dereference via the genapic,
so it's pointless to hide that indirection via these ugly macros.
Furthermore, it also obscures subarchitecture details.
So replace it with apic->irq_dest_mode / etc. accesses.

int_delivery_mode is supposed to mean 'interrupt delivery mode', but
it's quite a misnomer as 'int' we usually think of as an integer type ...
The standard naming for such attributes is 'irq' - so rename the following
fields and macros:
int_delivery_mode => irq_delivery_mode
INT_DELIVERY_MODE => IRQ_DELIVERY_MODE
int_dest_mode => irq_dest_mode
INT_DEST_MODE => IRQ_DEST_MODE

Impact: cleanup
x86 subarchitectures each defined a "apic_id_registered()" method,
which could be an inline function depending on which subarch we build
for, and which was also the name of a genapic field.
Untangle this namespace spaghetti by giving each of the instances
a separate name.
Also remove wrapper macro obfuscation.

Impact: refactor code
x86 subarchitectures each defined a "acpi_madt_oem_check()" method,
which could be an inline function, or an extern, or a static function,
and which was also the name of a genapic field.
Untangle this namespace spaghetti by setting ->acpi_madt_oem_check()
to NULL on those subarchitectures that have no detection quirks,
and rename the other ones (summit, es7000) that do.
Also change default_acpi_madt_oem_check() to handle NULL entries,
and clean its control flow up as well.

Clean up the APIC driver template:
- order fields properly
- use the macro names explicitly (so that they can be renamed later)
- fill in NULL entries as well

Rename genapic-> to apic-> references because in a future chagne we'll
open-code all the indirect calls (instead of obscuring them via macros),
so we want this reference to be as short as possible.

Impact: cleanup, solve 80 columns wrap problems
It would be cleaner to rename all the mpc->mpc_X fields to
mpc->X - that alone would give 4 characters per usage site.
(we already know that it's an 'mpc' entity -
no need to duplicate that in the field too)

Impact: cleanup, solve 80 columns wrap problems
mpc_config_oemtable should be renamed to mpc_oemtable.
The reason: the 'c' in MPC already means 'config' -
no need to repeat that in the type name.

Impact: cleanup, change parameter passing
* Change genapic interfaces to accept cpumask_t pointers where possible.
* Modify external callers to use cpumask_t pointers in function 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.
* 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))
...
become:
if (!cpus_equal(cpu_online_map, cpumask_of_cpu(cpu)))
...
* Other minor code optimizations (like using cpus_clear instead of
CPU_MASK_NONE, etc.)
Applies to linux-2.6.tip/master.

Impact: clean up
We can autodetect those system that need cluster apic, and update genapic
accordingly.
We can also remove wakeup.h for e7000, because it's default one is now
the same as overall default mach_wakecpu.h

so we can merge io_apic_32.c and io_apic_64.c
v2: Use cpu_online_map as target cpus for bigsmp, just like 64-bit is doing.
Also remove some unused TARGET_CPUS macro.
v3: need to check if desc is null in smp_irq_move_cleanup
also migration needs to reset vector too, so copy __target_IO_APIC_irq
from 64bit.
(the duplication will go away once the two files are unified.)
