Rusty Russell 5c6cb5e2b1 cpumask: remove cpumask_t assignment from vector_allocation_domain()
Impact: cleanup

It's not legal to do assignments into cpumask_var_t; they will soon be of
variable length.

So explicitly clear the mask and set the first word, rather than using
assignment.

Ingo Molnar 1f5bcabf1b x86: apic: simplify secondary CPU wakeup methods
Impact: cleanup

- rename apic->wakeup_cpu  to apic->wakeup_secondary_cpu, to
  make it apparent that this is an SMP-only method

- handle NULL ->wakeup_secondary_cpus to mean the default INIT
  wakeup sequence - this allows simplification of the APIC
  driver templates.

Yinghai Lu 2b6163bf57 x86: remove update_apic from x86_quirks
Impact: cleanup

x86_quirks->update_apic() calling looks crazy. so try to remove it:

 1. every apic take wakeup_cpu member directly
 2. separate es7000_apic to es7000_apic_cluster
 3. use uv_wakeup_cpu directly

Ingo Molnar 8e6dafd6c7 x86: refactor x86_quirks support
Impact: cleanup

Make x86_quirks support more transparent. The highlevel
methods are now named:

  extern void x86_quirk_pre_intr_init(void);
  extern void x86_quirk_intr_init(void);

  extern void x86_quirk_trap_init(void);

  extern void x86_quirk_pre_time_init(void);
  extern void x86_quirk_time_init(void);

This makes it clear that if some platform extension has to
do something here that it is considered ... weird, and is
discouraged.

Also remove arch_hooks.h and move it into setup.h (and other
header files where appropriate).

Ingo Molnar 9be1b56a3e x86, apic: separate 32-bit setup functionality out of apic_32.c
Impact: build fix, cleanup

A couple of arch setup callbacks were mistakenly in apic_32.c, breaking
the build.

Also simplify the code a bit.

Ingo Molnar 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.
