how to pick up a patch from a mail

[Asutosh Das]

Hi
Say I want to pick up a patch
https://www.google.co.in/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&ved=0CC4QFjAA&url=http://lists.linaro.org/pipermail/linaro-kernel/2011-April/000250.html&ei=FXL5UIy-KYKErQf47oGgAg&usg=AFQjCNGVUHMUQJ6gAhSkXJb7rWO6h_xA9A&bvm=bv.41248874,d.bmk

how do i apply it directly to my branch without copying it ?

I have tried git am and git mail-info, but i am not sure if I am using
the correct command.

Can you please let me know the correct command ?
