This MSI driver can be used on 83xx/85xx/86xx board.
In this driver, virtual interrupt host and chip were
setup. There are 256 MSI interrupts in this host, Every 32
MSI interrupts cascaded to one IPIC/MPIC interrupt.
The chip was treated as edge sensitive and some necessary
functions were setup for this chip.
Before using the MSI interrupt, PCI/PCIE device need to
ask for a MSI interrupt in the 256 MSI interrupts. A 256bit
bitmap show which MSI interrupt was used, reserve bit in
the bitmap can be used to force the device use some designate
MSI interrupt in the 256 MSI interrupts. Sometimes this is useful
for testing the all the MSI interrupts. The msi-available-ranges
property in the dts file was used for this purpose.

If we're using vcpu_info mapping, then make sure its restored on all
processors before relasing them from stop_machine.
The only complication is that if this fails, we can't continue because
we've already made assumptions that the mapping is available (baked in
calls to the _direct versions of the functions, for example).
Fortunately this can only happen with a 32-bit hypervisor, which may
possibly run out of mapping space. On a 64-bit hypervisor, this is a
non-issue.

When operating on an unpinned pagetable (ie, one under construction or
destruction), it isn't necessary to use a hypercall to update a
pud/pmd entry. Jan Beulich observed that a similar optimisation
avoided many thousands of hypercalls while doing a kernel build.
One tricky part is that early in the kernel boot there's no page
structure, so we can't check to see if the page is pinned. In that
case, we just always use the hypercall.
