0149e65081 vm-device: support batch update interrupt source group GSI
Split interrupt source group restore into two steps, first restore
the irqfd for each interrupt source entry, and second restore the
GSI routing of the entire interrupt source group.

This patch will reduce restore latency of interrupt source group,
and in a 200-concurrent restore test, the patch reduced the
average IOAPIC restore time from 15ms to 1ms.

a718716831 vfio: fix vfio device fail to initialize issue for 64k page size
Currently, vfio device fails to initialize as the msix-cap region in BAR
is mapped as RW region.

To resolve the initialization issue, this commit avoids mapping the
msix-cap region in the BAR. However, this solution introduces another
problem where aligning the msix table offset in the BAR to the page
size may cause overlap with the MMIO RW region, leading to reduced
performance. By enlarging the entire region in the BAR and relocating
the msix table to achieve page size alignment, this problem can be
overcomed effectively.

eca75dcfc9 vfio: align memory region size and address to PAGE_SIZE
In current implementation, memory region used in vfio is assumed to
align to 4k which may cause error when the PAGE_SIZE is not 4k, like on
Arm, it can be 16k and 64k.

Remove this assumption and align memory resource used by vfio to
PAGE_SIZE then vfio can run on host with 64k PAGE_SIZE.

2b150ac2ea pci, virtio-devices: Restore proper BAR type
When restoring a VM, the BAR type can be found directly from the
snapshot resources. It is more reliable than the previous method which
was using self.use_64bit_bar from VirtioPciDevice because at the time
the BARs are allocated, the VirtioDevice hasn't been restored yet,
meaning the way to determine the value of use_64bit_bar is wrong for a
device like vDPA. At this time, the device type is not known and relying
on the stored resources is the only reliable way.

89a2562c5a pci: Optimise MSI-X table programming
With an updated Linux kernel the kernel reprograms the same table entry
in the MSI-X table multiple times. Fortunately it does so with entry
masked (the default.)

The costly part of MSI-X table reprogramming is going out to the host
kernel to update the GSI routing entries. This change makes three
optimisations.

1. If the table entry is unchanged: skip handking updates
2. Only update the GSI routing table if the table entry is unmasked
   (this skips extra calls to the ioctl() for reprogramming the
    entries.)
3. Only generate a message on entry unmasking if the global MSI-X enable
   bit is set.

Fixes: #4273
