* Each cpu saves its state as it enters kdb or before it enters code
which cannot call kdb.
* Allow btp on process 0 for a specified cpu.
* Add btt command, backtrace given a struct task address.
* btc command no longer switches cpus, instead it uses the saved data.
* bta shows the idle task on each cpu as well as real tasks, the idle
task could be handling an interrupt.
* ps command shows the idle task on each cpu.
* ps checks that the saved data for a cpu matches the process running on
that cpu and warns about stale saved data or no saved data at all.
* Remove special cases for i386 backtrace from common code and simplify
common bt code.
* Clean up kdb interaction with CONFIG_SERIAL_CONSOLE.
* Do not automatically repeat commands after the user typed 'q'.
* O(1) scheduler patch changes the process cpu field but does not set
any indicator that O(1) is being used. Adjust kdb_process_cpu() by
hand after applying O(1).
* Add kdb_print_nameval() to common code.
* Convert tests of cpu_online_map to cpu_online() macro.
* module.h needs errno.h when compiling with CONFIG_MODULES=n.
* Correct duplicate breakpoint handling.
* Do not try to send IPI during a catastrophic error, send_ipi can hang
and take kdb with it.
* kdb memmap command is i386 only, restrict it.
* Add large block device (LBD) support from XFS tree. Eric Sandeen.
* kdb v4.0-2.4.20-common-1.

the initial cpu, installs the global breakpoints then releases the
other cpus.

software breakpoints.
