2.4.x).

IDE: kill warning

The Daynaport driver was superseded by the mac8390 driver (from Ray Knight)

Remove m68k fallback function for virtual/physical address conversions
(should there be any driver relying on this, that driver is seriously b0rken)
(from Roman Zippel)

Move m68k low-level iomap definitions from asm/io.h to asm/raw_io.h, so zorro.h
and nubus.h can include raw_io.h instead of io.h (as suggested by Richard
Zidlicky)

M68k needs WANT_PAGE_VIRTUAL (from Richard Zidlicky)

M68k input drivers cleanup:
  - Remove remnants from the old input layer:
      o Config.help entries for the Amiga and Atari mouse drivers
      o Apollo keyboard code (including beep support)
      o Dummy keyboard initialization, keyboard repeat, and keyboard LEDs code
        for MVME147, Sun-3, Sun-3x,
      o Makefile entries for Atari keyboard, mouse and joystick drivers, and
        the HP300 Human Interface Loop driver
      o kbd-reset kernel command line parameters
      o defconfig entry for the Amiga mouse driver
      o Mac ADB mouse driver glue
      o Amiga and Mac ADB mouse driver minors
  - Always include new input layer configuration data

Prepend Q40/Q60 specific RTC definitions with Q40_

Allow to disable macfb

Add asm/percpu.h for m68k

Export m68k_memoffset

Define NVRAM_BYTES to 50 on Atari

Add user_tid argument to do_fork() calls (from Roman Zippel)

M68k build fixes, caused by kbuild changes in 2.5.41:
  - 68040 Floating Point and 68060 Integer and Floating Point Support Packages:
    use cpp includes instead of gas includes
  - Add `$(obj)' and `$(src)' where necessary to fix building of generated
    header files

2.5.44 linker file updates for m68k:
  - .*.init got renamed to .init.* to allow -ffunction-sections
  - discard .exit* sections like most other ports do

Convert core Amiga code to new local_irq*() framework

Re-add lost forward declarations of arch-specific *_mksound() routines, we need
them for the m68kspkr driver.

Add asm/kmap_types.h for m68k

M68k irq updates (most from Roman Zippel):
  - Update m68k to new irq API in 2.5.29
  - synchronize_irq() takes a parameter now
  - Remove obsolete definitions
  - Avoid too much inline assembly in __xchg
  - Add irqs_disabled(), which appeared in 2.5.34
  - Add missing implementation for in_atomic() (introduced in 2.5.35)

M68k: fix init_task section

M68k: Enable CONFIG_GENERIC_ISA_DMA (appeared in 2.5.31) if we have ISA only.

Convert m68k cache macros to inline functions

M68k: Fix missing/superfluous includes

Enable the console if CONFIG_VT=y

M68k: The INIT_SIGNALS() macro got an argument in 2.5.34

HP9000/300: Replace remaining readb() and friends by in_8() and friends

M68k IDE lock fixes:
  - Kill warning: ide_{get,release}_lock() can be real routines only if
    IDE_ARCH_LOCK is defined, the same is true for ide_intr_lock
  - Use the correct lock for ide_{get,release}_lock()

Compile fix if fbcon-mac is used with vesafb (from 2.4.20-pre7)

Genrtc updates:
  - Add genrtc wrappers
  - Export mach_hwclk for modular genrtc

M68k dump_stack() updates:
  - Let dump_stack() call show_trace() (cfr. ia32)
  - Separate show_registers() from show_stack()
  - Fix for dump_stack() becoming an arch-independent routine (from 2.4.x)

Misc compile fixes for m68k:
  - missing and superfluous casts
  - unused code

Fix dyslexia in Amiga keyboard driver

M68k epoll: add POLLREMOVE

M68k: revive csum_partial_copy_nocheck() after csum_partial_copy() was removed
in 2.5.44 (from Roman Zippel)

Since m68kspkr can be a module, we need to initialize mach_beep() for a modular
m68kspkr as well.
