branch annotation

[James Bond <jamesbond.2k.g@xxxxxxxxx>]

Hi,

before asking this question I had googled

http://www.google.co.in/search?sourceid=chrome&client=ubuntu&channel=cs&ie=UTF-8&q=branch+annotation

but no useful thing came in my search results.

I want to know the concept of Branch Annotation with respect to Linux Kernel use of likely() and unlikely()

Please give some links if you have any to share.
