Introduce KVM_SET_MSIX_NR and KVM_SET_MSIX_ENTRY two ioctls.
This two ioctls are used by userspace to specific guest device MSI-X entry
number and correlate MSI-X entry with GSI during the initialization stage.
MSI-X should be well initialzed before enabling.
Don't support change MSI-X entry number for now.

Windows 2008 accesses this MSR often on context switch intensive workloads;
since we run in guest context with the guest MSR value loaded (so swapgs can
work correctly), we can simply disable interception of rdmsr/wrmsr for this
MSR.
A complication occurs since in legacy mode, we run with the host MSR value
loaded. In this case we enable interception. This means we need two MSR
bitmaps, one for legacy mode and one for long mode.

According to "Documentation/printk-formats.txt", if the type is
dependent on a config option for its size, like resource_size_t,
we should use a format specifier of its largest possible type and
explicitly cast to it.

On module unload call rcu_barrier(), this is needed as synchronize_rcu()

The VLAN 8021q driver needs to call rcu_barrier() when unloading the module,
instead of syncronize_net(). This is needed to make sure that outstanding
call_rcu() callbacks have completed, before the callback function code is
removed on module unload.

Currently we support only PCIe NIC functions zero and one, and FCoE
functions as 3 and 4. Future configurations can mix these up in any
fashion.
This patch removes the 0-1 dependancy and allows usage of any of the 4
functions. We also find the alternate NIC function (if exist) and
determine our port number based on the comparison of the two functions:
Lower function number gets first port, higher function gets second port.

This helps with bad latencies for large reads from /dev/zero, but might
conceivably break some application that "knows" that a read of /dev/zero
cannot return early. So do this early in the merge window to give us
maximal test coverage, even if the patch is totally trivial.
Obviously, no well-behaved application should ever depend on the read
being uninterruptible, but hey, bugs happen.
