Jason Wessel 974460c5bf kgdb: allow static kgdbts boot configuration
This patch adds in the ability to compile the kgdb internal test
string into the kernel so as to run the tests at boot without changing
the kernel boot arguments.  This patch also changes all the error
paths to invoke WARN_ON(1) which will emit the line number of the file
and dump the kernel stack when an error occurs.

You can disable the tests in a kernel that is built this way
using "kgdbts="

If you say Y here, it will be possible to remotely debug the
kernel using gdb. Documentation of kernel debugger is available
at http://kgdb.sourceforge.net as well as in DocBook form
in Documentation/DocBook/. If unsure, say N.

Share a serial console with kgdb. Sysrq-g must be used
to break in initially.

This is a kgdb I/O module specifically designed to test
kgdb's internal functions. This kgdb I/O module is
intended to for the development of new kgdb stubs
as well as regression testing the kgdb internals.
See the drivers/misc/kgdbts.c for the details about
the tests. The most basic of this I/O module is to boot
a kernel boot arguments "kgdbwait kgdbts=V1F100"

Run the kgdb tests on boot up automatically without the need
to pass in a kernel parameter

default "V1F100"
help
This is the command string to send the kgdb test suite on
boot. See the drivers/misc/kgdbts.c for detailed
information about other strings you could use beyond the
default of V1F100.
