Subject: [patch 0/2]  Improve the markup_oops.pl script

Hi,

the following 2 patches enhance the markup_oops.pl script in two ways
Patch 1: Add support for putting register values in the asm dump
Patch 2: Add support for 64 bit X86

The output (on a 32 bit OS with a "make me oops" example module) looks like
the pasted dump; for the instruction where the oops happened, as well as
a few instructions before that where the dumper can determine the register value.
the value is appended on said line.


 	if (bar-1) { 
 f8436012:	8b 45 fc             	mov    -0x4(%ebp),%eax 
 f8436015:	48                   	dec    %eax 
 f8436016:	74 09                	je     f8436021 <foo_bar+0x21> 
 		bar = bar * 5; 
 f8436018:	8b 45 fc             	mov    -0x4(%ebp),%eax

 	return bar; 
 f8436024:	8b 45 fc             	mov    -0x4(%ebp),%eax 
 }
