Last change on this file since a5c86478 was f6069801, checked in by Jakub Jermar <jakub@…>, 15 years ago

Add generic support for kernel stack traces.
One can print "synchronous" stack traces or stack traces
based on istate information (both kernel and uspace stacks).
Kernel stack traces resolve addresses to symbols, if symbols
are included in the kernel.
