ACPI: Remove interpreter debugger and kdb directories. These ultimately 

didn't prove useful enough to be used on a regular basis.

Using the ACPI debugger with kdb
--------------------------------
ACPI CA includes a full-featured debugger, which allows the examination of
a running system's ACPI tables, as well as running and stepping through
control methods.
Configuration
-------------
1) Edit the main acpi Makefile. On the ACPI_CFLAGS line, remove the '#', thus
enabling the debugger.
2) Download the latest kdb patch from:
ftp://oss.sgi.com/www/projects/kdb/download/ix86/
Follow the instructions at http://oss.sgi.com/projects/kdb/ on how to
install the patch and configure KDB.
3) This would probably be a good time to recompile the kernel, and make sure
kdb works (Hitting the Pause key should drop you into it. Type "go" to exit
it.
4) The kdb <--> ACPI debugger interface is a module. Type "make modules", and
it will be built and placed in drivers/acpi/kdb.
5) Change to that directory and type "insmod kdbm_acpi.o". This loads the
module we just built.
6) Break back into kdb. If you type help, you should now see "acpi" listed as
a command, at the bottom.
7) Type "acpi". You are now in the ACPI debugger. While hosted by kdb, it is
wholly separate, and has many ACPI-specific commands. Type "?" or "help"
to get a listing of the command categories, and then "help <category>" for
a list of commands and their descriptions
