[Xen-devel] Make sure git clone gets the right kernel branch

[Jeremy Fitzhardinge <jeremy@xxxxxxxx>]

When cloning kernel repo:
  1. make remote called "xen" rather than the default "origin"
  2. directly checkout the desired branch, rather than the default then
     the desired one

Git 1.5 doesn't support -b on git clone, and seems to do something odd
with the checkout branch argument, so avoid using the newer commandline
options.
