Patch from Nicolas Pitre

Those defines are incomplete and not using them by
instead using the explicit flags makes for clearer code.

Essentially, this set of changes:
1. makes the register usage in head.S more sane
2. makes way for passing the location of the tagged list via "r2"
   (as the booting document suggests)

This brings the latency back to previous levels, and in
fact seems to drive it a bit lower.

There were a few variants on the list trying to work out what the valid
ranges to verify for write are but they sort of missed the point, if you
can load new firmware you can have fun anyway.

The patch below contains cleanups under sound/oss/ including the
following:
- make needlessly global code static

  and the other one was already stale)
- removed the following unused global functions:
  - cs4232.c: init_cs4281
  - emu10k1/hwaccess.c: sumVolumeToAttenuation
  - emu10k1/hwaccess.c: emu10k1_set_stop_on_loop
  - sb_common.c: sb_dsp_disable_midi
  - sb_common.c: sb_dsp_disable_recording
  - wavfront.c: attach_wffx
- cs46xx.c: #ifndef CS46XX_ACPI_SUPPORT cs46xx_pm_callback
- emu10k1/hwaccess.c: #ifdef DBGEMU emu10k1_writefn0_2
- opl3sa2.c: remove the unused struct opl3sa2_dev
- removed the following unused EXPORT_SYMBOL's:
  - ac97.c: ac97_set_mixer
  - ac97.c: ac97_get_register
  - ac97.c: ac97_get_mixer_scaled
  - sb_common.c: sb_dsp_disable_midi

IN_STRING_C was an i386-specific hack by Andi Kleen to provide out-of-line
versions of some lib/string.c functions that aren't directly used on i386
(because there are inline assembly versions).

This can cause problems if gcc chooses to transparently replace a call to one
string function with a call to another string function (the example Andi gave
was a replacement of a sprintf call with a strcpy call) which generates a
function call to the replacement function.

The problems observed by Andi only occur in recent kernels without
-fno-unit-at-a-time.

With -ffreestanding it can't even cause any problems in case we'd one day drop
the -fno-unit-at-a-time since gcc mustn't assume in a freestanding environment
that all standard C library functions are available.

The effect of this patch is a small space saving in the kernel.

  If you remove any code inside the #ifdef CONFIG_QNX4FS_RW we might as well
  remove the option "config QNX4FS_RW" altogether.  It's horribly broken, and
  I don't intend to fix it; while I was thinking about how to properly
  implement write-support, somebody else went away and did it.  As that
  alternative seems to work well and is being actively maintained, I won't try
  to reinvent it.
