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

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

Hi

The attached patch implements the idle=poll option in the kernel when
running on Xen. This causes the kernel to use a polling loop rather
than hypercall down to block. I have found this useful to profile the
amount of sleep cycles when using xenoprof, there may be other uses.

Thanks
