kvm_get_dirty_log() is a helper function for
kvm_vm_ioctl_get_dirty_log() which

- sanity checks
- bitmap scan to check if the slot is dirty
- copy_to_user()
Considering the fact that x86 is not using this anymore and sanity
checks must
be done before kvm_ia64_sync_dirty_log(), we can say that this is not
working
for code sharing effectively. So we just remove this.
This patch plus 4/4 broke dirty bitmap updating on PPC. I didn't get
around to track down why, but I figured you should now. Is there any
way to get you a PPC development box? A simple G4 or G5 should be 200$
on ebay by now :).
Best to revert these patches and re-apply when fixed.
Please revert. Sincerely sorry.
I'll fix as soon as possible and re-submit when test on PPC gets OK.
