Hmmm what are you asking? Is this a question for c-programming? Try 
linux-newbie for any follow-up questions.

This tells you this information is for your first and only processor (because 
there are no more listings)

In Laymen terms, what is the Processor name

Not sure, but if you have a multiprocessor machine you need to match this 
exactly for both processors.

Cache Size. More is better ;)

Does it suffer from various bugs that previous processors have? No, your 
processor is all good.

It supports floating point exceptions

Not sure, the wp is something a hardware guru can answer.

These are all the "extra" instructions and features it supports. Interesting 
ones are:
sse/sse2 multimedia instructions
ht hyperthreading
acpi I forget the acronym, but this is for advanced configuration and power 
saving features
pae Page address extentions, it lets your support 4GB of memory instead of 
16M.

An irellevant calculation Linux uses to program its idle loop. Can be a VERY 
GENERIC indicator of processor speed but should never be relied up as any 
sort of quantatative benchmark.

So what was it you wanted info about? Could you be more specific? All of this 
info is fairly self-explanatory. Did you need to find out if your processor 
supports a specific feature?
