Enabling PARAVIRT stuff in Fedora kernels

[Roland Dreier]

Hi,

I just tried the latest Fedora rawhide kernel
(2.6.26-0.115.rc9.git2.fc10.x86_64) in a kvm virtual machine, and I
noticed that it doesn't have all the paravirtual goodness available in
2.6.26.  The cost of setting PARAVIRT, PARAVIRT_CLOCK and
PARAVIRT_GUEST to 'y' is suposed to be pretty minimal on bare metal,
and it gives a nice boost running inside kvm.  Have you guys
considered turning on these options for Fedora kernels?

Thanks,
  Roland
