2008-01-30x86: pull bp calculation earlier into the backtrace pathArjan van de Ven
Right now, we take the stack pointer early during the backtrace path, but only calculate bp several functions deep later, making it hard to reconcile the stack and bp backtraces (as well as showing several internal backtrace functions on the stack with bp based backtracing). This patch moves the bp taking to the same place we take the stack pointer; sadly this ripples through several layers of the back tracing stack, but it's not all that bad in the end I hope.

2008-01-30x86: add the capability to print fuzzy backtracesArjan van de Ven
For enhancing the 32 bit EBP based backtracer, I need the capability for the backtracer to tell it's customer that an entry is either reliable or unreliable, and the backtrace printing code then needs to print the unreliable ones slightly different. This patch adds the basic capability, the next patch will add a user of this capability.

2007-10-13Delete filenames in comments.Dave Jones
Since the x86 merge, lots of files that referenced their own filenames are no longer correct. Rather than keep them up to date, just delete them, as they add no real value. Additionally: - fix up comment formatting in scx200_32.c - Remove a credit from myself in setup_64.c from a time when we had no SCM - remove longwinded history from tsc_32.c which can be figured out from git.
