Ingo Molnar e2780a68f8 x86, apic: merge genapic.h into apic.h
Impact: cleanup

Reduce the number of include files to worry about.
Also, most of the users of APIC facilities had to
include genapic.h already, which embedded apic.h,
so the distinction was meaningless.

[ include apic.h from genapic.h for compatibility. ]

Ingo Molnar abfa584c8d x86: set ->trampoline_phys_low/high on 64-bit too
64-bit x86 has zero for ->trampoline_phys_low/high, but the smpboot
code can use these values - so it's better to set them up to their
correct values.

Ingo Molnar f8987a1093 x86, genapic: rename int_delivery_mode, et. al.
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

Ingo Molnar 306db03b0d x86: clean up apic->acpi_madt_oem_check methods
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.

Ingo Molnar 9a6801da55 x86: remove APIC_INIT / APICFUNC / IPIFUNC
The APIC_INIT() / APICFUNC / IPIFUNC macros were ugly and obfuscated
the true identity of various APIC driver methods.

Now that they are not used anymore, remove them.

Ingo Molnar c8d46cf06d x86: rename 'genapic' to 'apic'
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.
