Use the new aural error reporting framework to signal kernel bugs. Emit the
sound at the end of the __warn(), so the WARN_* are all covered.
If panic_on_warn is set, panic() will play its sound and never return,
so there is no risk to emit two sounds or the wrong one.

driver is simple, requires just a few register writes to work,
the hardware is extremely cheap and is already present on most machines.

Use the new aural error reporting framework when reporting an oops. The
sound is emitted at the end of oops_exit(), to avoid interfering with other
oops actions, like stack dump.

, creates a procfs handler useful to test
the error reporting.

Use the new aural error reporting framework to signal kernel panic. The
error sound is emitted between the stack dump and the kexec jump.
