Subject[ANNOUNCE] mdb: Merkey's Linux Kernel Debugger 2.6.27-rc5 released
 Added local APIC and IOAPIC register support.  Removed all volatile 
declarations from the code. Instrumented barrier() compiler
directives. streamlined mdb-list parser. Added hard
NMI interrupt capability to generate a hard NMI to a target
processor for debugging a hung processor via the APIC ASSERT_INT
command.

ISSUES:

remote read of another processors local APIC registers has been
instrumented, but I am having problems with it working on all
systems. I have tried both physical and logical command modes
and I note that smptboot.c also relies on it for error reporting.

At present, it is insufficiently tested and some other eyes and
testing would be helpful.
