Subject: [PATCH 00/16] Cleanups to io_apic.c

Hi Ingo,

Here's a series of little cleanup patches to kernel/apic/io_apic.c which
I fixed as I was reviewing the code.

There are a few classes of cleanup here:
 - Unification of 32 and 64-bit variants, where they are functionally
   identical.

 - Removing unnecessary #ifdef CONFIG_X86_32/64 (similar to unification,
   except its code which is at worst a no-op on the other platform).
   This cleans up the appearance of the code, and makes compile-test
   coverage broader.  For the 82093AA workaround, the test should be
   more fine-grained (ie, actually look at the I/O APIC version).

 - Restructure loops to use more conventional forms (lots of odd loops
   which can be easily represented by a plain for() loop)

 - Fix some comments, delete redundant decls, etc.

Jeremy Fitzhardinge (12):
      x86/acpi: acpi_parse_madt_ioapic_entries: remove redundant braces
      x86/ioapic.c: ioapic_modify_irq is too large to inline
      x86/ioapic.c: unify __mask_IO_APIC_irq()
      x86/ioapic.c: remove #ifdef for 82093AA workaround
      x86/ioapic.c: remove redundant declaration of irq_pin_list
      x86/ioapic.c: move lost comment to what seems like appropriate place
      x86/ioapic.c: convert io_apic_level_ack_pending loop to normal for() loop
      x86/ioapic.c: simplify add_pin_to_irq_node()
      x86/ioapic.c: convert replace_pin_at_irq_node to conventional for() loop
      x86/ioapic.c: clean up replace_pin_at_irq_node logic and comments
      x86/ioapic.c: convert __target_IO_APIC_irq to conventional for() loop
      x86/ioapic.c: unify ioapic_retrigger_irq()
