kdb,kgdb: Allow arbitrary kgdb magic knock sequences

2011-08-01T18:23:59+00:00

The first packet that gdb sends when the kernel is in kdb mode seems
to change with every release of gdb.  Instead of continuing to add
many different gdb packets, change kdb to automatically look for any
thing that looks like a gdb packet.

Example 1 cold start test:
echo g > /proc/sysrq-trigger
$D#44+

Example 2 cold start test:
echo g > /proc/sysrq-trigger
$3#33

The second one should re-enter kdb's shell right away and is purely a
test.

kdb: Remove all references to DOING_KGDB2

2011-08-01T18:23:59+00:00

The DOING_KGDB2 was originally a state variable for one of the two
ways to automatically transition from kdb to kgdb.  Purge all these
variables and just use one single state for the transition.

kdb,kgdb: Implement switch and pass buffer from kdb -> gdb

2011-08-01T18:23:59+00:00

When switching from kdb mode to kgdb mode packets were getting lost
depending on the size of the fifo queue of the serial chip.  When gdb
initially connects if it is in kdb mode it should entirely send any
character buffer over to the gdbstub when switching connections.

Previously kdb was zero'ing out the character buffer and this could
lead to gdb failing to connect at all, or a lengthy pause could occur
on the initial connect.

kdb: cleanup unused variables missed in the original kdb merge

2011-08-01T18:23:58+00:00

The BTARGS and BTSYMARG variables do not have any function in the
mainline version of kdb.
