synchronize_irq() waits for hard irq and threaded handlers to complete

In course of the sdhci/sdio discussion with Russell about killing the

The rationale for this is, that sdio hardware can lack proper

This v2 series changes the approach from my original virtualization
multicast patch series [0] by abandoning completely the multicast
issues and instead generalizing an approach for virtualization
backends. There are two things in common with virtualization
backends:
From: "Luis R. Rodriguez"
The xen-netback driver is used only to provide a backend
interface for the frontend. The link is the only thing we
use, and that is used internally for letting us know when the
xen-netfront is ready, when it switches to XenbusStateConnected.
Note that only when the both

It doesn't make sense for some interfaces to become a root bridge
at any point in time. One example is virtual backend interfaces
which rely on other entities on the bridge for actual physical
connectivity. They only provide virtual access.

From: "Luis R. Rodriguez"
Some interfaces do not need to have any IPv4 or IPv6
addresses, so enable an option to specify this. One
example where this is observed are virtualization
backend interfaces which just use the net_device
constructs to help with their respective frontends.

The purpose of using a static MAC address of FE:FF:FF:FF:FF:FF

Since simple_strtoul() has been deprecated, replace it with kstrtouint().
Also, since return code checking for this new function is enforced, add a
check to ensure that the conversion has succeeded.

If we mount the same cgroupfs in serveral mount points, and then
umount all of them, kill_sb() will be called only once.
Therefore it's wrong to increment top_cgroup's refcnt when we find
an existing cgroup_root.
