Updates to kdb v4.4-2.6.16-{common,i386,ia64}-1, moving to -2. Mainly
to get more forceful with stuck cpus on IA64, where the "non-maskable"
interrupt is masked by local_irq_disable().
We finally get decent backtraces on stuck IA64 cpus. It took a long
time to get there, KDB could not change until the base kernel could
cope with INIT and recover correctly.

* Add some more xpc flags. Dean Nelson, SGI.
* Replace open coded counter references with atomic_read().
* Pass early_uart_console to early_uart_setup(). Francois
Wellenreiter, Bull.
* Replace open code with for_each_online_cpu().
* If cpus do not come into kdb after a few seconds then let
architectures send a more forceful interrupt.
* Close a timing race with KDB_ENTER_SLAVE.
* kdb v4.4-2.6.16-common-2.

Thanks for this new version, however I'm looking forward to see
kdb maintained also for the x86_64 architecture. Currently I have
got as far as forward-porting it to a level where it "works" except
for one annoying issue where setjmp/longjmp looks to be broken:

I've not tried latest kdb, but you should find the patch below still
works (removing that unnecessary KDB_STATE_SET(LONGJMP) is probably
irrelevant, just something I did on the way, and which does no harm).

Problem is due to the mixed C/asm implementation of setjmp/longjmp.
Replace that with one written entirely in assemply and it will work.
Here's mine:

Thanks, it's obviously a better way to do it, I've tested it and
made it into a patch:
diff --git a/arch/x86_64/kdb/kdbasupport.c b/arch/x86_64/kdb/kdbasupport.c
