Back in 2006 the "udbg-immortal" kernel option has been introduced:

  >  [PATCH] powerpc: Add udbg-immortal kernel option

...but I could not find it documented anywhere in the sources. 
This patch adds it to Documentation/kernel-parameters.txt.

Thanks for documenting this!

Suggested grammatical tweaks:

s/options/option/
s/help "seeing"/help to "see"/
