28a3c93d11 x86, pic: Fix section mismatch in legacy pic
Move legacy_pic chip dummy functions out of init section as they might
be referenced at run time.

b81bb373a7 x86, pic: Make use of legacy_pic abstraction
This patch replaces legacy PIC-related global variable and functions
with the new legacy_pic abstraction.

ef3548668c x86, pic: Introduce legacy_pic abstraction
This patch makes i8259A like legacy programmable interrupt controller
code into a driver so that legacy pic functions can be selected at
runtime based on platform information, such as HW subarchitecure ID.
Default structure of legacy_pic maintains the current code path for
x86pc.

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).

c46e62f735 i8259: fix final ugliness
Introduce IRQx_VECTOR on 32-bit, so that #ifdef noise is kept
down. There should be no object code change.

[ mingo@elte.hu: merged to x86/irq not x86/i8259 due to x86/irq having
  restructured the vector code into asm-x86/irq_vectors.h, which this
  patch touches. ]

21fd5132b2 x86: automatical unification of i8259.c
Make conversion of i8259 very mechanical -- i8259 was generated by
 diff -D, with too different parts left in i8259_32 and
i8259_64.c. Only "by hand" changes were removal of #ifdef from middle
of the comment (prevented compilation) and removal of one static to
allow splitting into files.

Of course, it will need some cleanups now, and those will follow.
