[PATCH/RFC] Fixing kd_mksound again...

[Tom Rini <trini@kernel.crashing.org>]

Currently in linuxppc_2_4 (and 2.5) we always use the PC-style
kd_mksound on __powerpc__ (=> PPC32, not PPC64 ?) and override that in
the pmac port to something more sensible.  I would like to propose the
following patch which expands the test to __powerpc__ && CONFIG_6xx.
While it is possible to override kd_mksound later on, in a
per-board/platform fashion, I think it makes the most sense to default
to the PC-style version when we can be reasonably sure that it will work
(i.e., it does work on my LoPEC and I think Sandpoint X3 as well) and
otherwise assume that it won't (i.e., 405, Redwood4, probably 8xx).
In the cases where it currently isn't working anyhow[1] if someone wants
to make this work, they will have to override the given _kd_mksound
anyhow, so using the empty one by default is best here.

The following patch applies cleanly against both 2.4.19-rc1 and 2.5.24.

[1]: I bring this up since I just got a report that it doesn't work on
PPC405 systems, and based on the RW4 check in _devel in this code, I'm
not supprised.  This patch will supersede the current _devel part, of
course.
