Hi,
We encountered a vcpu-set issue on old xen, when I tried to confirm
if xen upstream xen has the same issue I find neither my upstream build
nor ubuntu 22.04 xen-hypervisor-4.16 work.
I can add vcpus(8->16) to my guest but I can not reduce vcpu number:

This patch synced PIRR with IRR when misx table updated, I ran same test
over 1.5 hours and did not reproduced it, without the patch, I could
reproduced within 10 minutes.

used old vector and dest cpu info, and when local IRQ enabled again,
interrupt been sent to wrong cpu and vector.
Looks sync PIR to IRR after MSI-X been updated is help for this issue.
BTW, I could not reproduced this issue if I disabled apicv.

xen_destroy_contiguous_region() used to exchange physically
contiguous memory with hypervisor, but it does not verify
that the memory is physically contiguous or no, passing
non-contiguous memory to xen_destroy_contiguous_region()

The correct check condition should be memory is in DMA area and
physically contiguous.
