In the case of where you have a system that is running in a
capped or overcommitted environment the user may see steal time
being reported in accounting tools such as top or vmstat. This can
cause confusion for the end user. To ease the confusion this patch set
adds the idea of consigned (expected steal) time. The host will separate
the consigned time from the steal time. The consignment limit passed to the
host will be the amount of steal time expected within a fixed period of
time. Any other steal time accruing during that period will show as the
traditional steal time.

Michael Wolf (5):
Alter the amount of steal time reported by the guest.
Expand the steal time msr to also contain the consigned time.
Add the code to send the consigned time from the host to the guest
Add a timer to allow the separation of consigned from steal time.
Add an ioctl to communicate the consign limit to the host.
