IDE I/O operations clean ups:
  - Kill warning about void return type not being ignored
  - Fix comment: Q40/Q60 also has a byte-swapped IDE interface

M68k IDE:
  - Update for new-style low-level IDE operations. Since so far no single
    m68k platform uses ISA/PCI I/O space for IDE, we always use the `raw' MMIO
    versions.
  - ATA_ARCH_LOCK was renamed to IDE_ARCH_LOCK
  - Define ide_ack_intr() and set IDE_ARCH_ACK_INTR

Resurrect dmasound:
  - Re-add dmasound to the build process
  - Update dmasound.h, which got missed in the dmasound update in 2.5.15
  - Compile fixes for core, Atari, Amiga Paula, and Q40:
      o Update for s/MINOR/minor/g changes
      o Add missing <linux/interrupt.h>
      o Fix spinlock typo

M68k: Use ptrace_check_attach instead of doing the checks ourselves (from
Andreas Schwab).

M68k: Fix sys_ipc() to return ENOSYS instead of EINVAL as appropriate.

SCSI: hosts.c uses CONFIG_*, hence it needs to include <linux/config.h>

M68k: Add pte_file() for Motorola MMUs (from Roman Zippel):
  - Add support for file file offsets in pte's (recycle unused _PAGE_COW bit)
  - Move swap macros into the mmu specific header
  - Fix swap macros (lowest two bits must be cleared)

M68k IDE: kill ide_ioreg_t and q40ide_ioreg_t

AFS and RXRPC: times must be unsigned long

Atyfb fixes for Atari (got reversed in 2.5.69):
  - Add missing allocation of default_par
  - Kill warnings in assignments

Ataflop: fix breakage after recent cleanups

strncpy() users. Sucker!

 - Pass in the "device" to remapping functions
 - add radeon CP resume ioctl
 - remove warnings and stale DMA debug code

Whether it works or not is unknown. I don't have the hardware.

sys_ioperm is only implemented on x86 (i386/x86_64).  Make the
ifdefs in vt_ioctl.c more explicit so the other architectures can
get rid of their stubs in favour of just using sys_ni_syscall in
the syscall table.

Maybe we should remove it altogether, it looks like remnants from
some very early X386 times (ie the Thomas Roell timeframe).

The noop io scheduler has a data corrupting bug, because q->last_merge
doesn't get cleared properly.  So do that in io scheduler core, and
remove the same code from deadline.

Also kill bio_rq_in_between(), it's not used by anyone anymore. rbtrees
are the hot thing these days.

And finally, remove a direct test for REQ_CMD in rq flags, use
blk_fs_request() instead.

Fix prototypes to match function definitions
