This is to allow us to decouple the DINO device from the board logic. The choice
of using a hard-coded constant (along with a comment) is to match how this is
already done for toc_addr. If it is decided later that these values need to be
configurable then they can easily be converted to qdev properties.

In migration resume phase, all unmasked msix vectors need to be
setup when loading the VF state. However, the setup operation would
take longer if the VM has more VFs and each VF has more unmasked
vectors.
The hot spot is kvm_irqchip_commit_routes, it'll scan and update
all irqfds that are already assigned each invocation, so more
vectors means need more time to process them.
vfio_pci_load_config
vfio_msix_enable
msix_set_vector_notifiers
for (vector = 0; vector < dev->msix_entries_nr; vector++) {
vfio_msix_vector_do_use
vfio_add_kvm_msi_virq
kvm_irqchip_commit_routes <-- expensive
}
We can reduce the cost by only committing once outside the loop.
The routes are cached in kvm_state, we commit them first and then
bind irqfd for each vector.
The test VM has 128 vcpus and 8 VF (each one has 65 vectors),
we measure the cost of the vfio_msix_enable for each VF, and
we can see 90+% costs can be reduce.

Commit ecebe53fe9 ("vfio: Avoid disabling and enabling vectors
repeatedly in VFIO migration") avoids inefficiently disabling and
enabling vectors repeatedly and lets the unmasked vectors be enabled
one by one.
But we want to batch multiple routes and defer the commit, and only
commit once outside the loop of setting vector notifiers, so we
cannot enable the vectors one by one in the loop now.
Revert that commit and we will take another way in the next patch,
it can not only avoid disabling/enabling vectors repeatedly, but
also satisfy our requirement of defer to commit.

When pulling or pushing an OS context from/to a CPU, we should
re-evaluate the state of the External interrupt signal. Otherwise, we
can end up catching the External interrupt exception in hypervisor
mode, which is unexpected.
The problem is best illustrated with the following scenario:
1. an External interrupt is raised while the guest is on the CPU.
2. before the guest can ack the External interrupt, an hypervisor
interrupt is raised, for example the Hypervisor Decrementer or
Hypervisor Virtualization interrupt. The hypervisor interrupt forces
the guest to exit while the External interrupt is still pending.
3. the hypervisor handles the hypervisor interrupt. At this point, the
External interrupt is still pending. So it's very likely to be
delivered while the hypervisor is running. That's unexpected and can
result in an infinite loop where the hypervisor catches the External
interrupt, looks for an interrupt in its hypervisor queue, doesn't
find any, exits the interrupt handler with the External interrupt
still raised, repeat...
The fix is simply to always lower the External interrupt signal when
pulling an OS context. It means it needs to be raised again when
re-pushing the OS context. Fortunately, it's already the case, as we
now always call xive_tctx_ipb_update(), which will raise the signal if
needed.

The Post Interrupt Priority Register (PIPR) is not restored like the
other OS-context related fields of the TIMA when pushing an OS context
on the CPU. It's not needed because it can be calculated from the
Interrupt Pending Buffer (IPB), which is saved and restored. The PIPR
must therefore always be recomputed when pushing an OS context.
This patch fixes a path on P9 and P10 where it was not done. If there
was a pending interrupt when the OS context was pulled, the IPB was
saved correctly. When pushing back the context, the code in
xive_tctx_need_resend() was checking for a interrupt raised while the
context was not on the CPU, saved in the NVT. If one was found, then
it was merged with the saved IPB and the PIPR updated and everything
was fine. However, if there was no interrupt found in the NVT, then
xive_tctx_ipb_update() was not being called and the PIPR was not
updated. This patch fixes it by always calling xive_tctx_ipb_update().
Note that on P10 (xive2.c) and because of the above, there's no longer
any need to check the CPPR value so it can go away.

Remove a possible source of error by removing REGINFO_SENTINEL
and using ARRAY_SIZE (convinently hidden inside a macro) to
find the end of the set of regs being registered or modified.
The space saved by not having the extra array element reduces
the executable's .data.rel.ro section by about 9k.

internal header, out of the public cpu.h.

The spec clarifies now that QEMU should not send a file descriptor in a
request to remove a memory region. Change it accordingly.
For libvhost-user, this is a bug fix that makes it compatible with
rust-vmm's implementation that doesn't send a file descriptor. Keep
accepting, but ignoring a file descriptor for compatibility with older
QEMU versions.
