[Xen-devel] Re: [PATCH]Allow the kernel to poll in the idle loop

["Amitabha Roy" <amitabha.roy@xxxxxxxxx>]

Bug fix to the patch :-$. Need to take care of the case where there is
no poll= option on the command line in which case we need to default
to xen_idle.

These are the final set of patches. Is anyone interested in having
these ? Then I can also work on and send out a similar patch for
x86_64.

Thanks
-Amitabha
