a5a242dcee stacktrace: print_stack_trace() cleanup 
- shorter code and better atomicity with regards to printk().

(It's been tested with the backtrace self-test code on i386 and x86_64.)

bfeeeeb991 stacktrace: don't crash on invalid stack trace structs 
This patch makes the stacktrace printout code \warn when the entries
pointer is unset rather than crashing when trying to access it in an
attempt to make it a bit more robust.

I was saving a stacktrace into an skb and forgot to copy it across skb
copies... I have since fixed the code, but it would have been easier
had the kernel not crashed in an interrupt.
