That hypercall is used when a PV kernel (re-)enables interrupts. See
xen_irq_enable. The purpose is to force the kernel to switch

Yes, I'm taking out patches from 4.4 and actually do have a working 4.9
kernel along with blktap. Tested networking and disk IO in it.
There are roughly 415 patches to 4.4 out of which some ~210+ are already
applied in 4.9 and ~220+ are already applied in 4.14. I dont have numbers
for 4.19 yet.

Yes, I'm running it in a HVM domU for development purpose.

Alright, I got the serial console and following is the crash log. Thank you
for pointing that out.

Nothing is getting logged. I suspect its because the kernel just goes in
halt state.
/var/log/kern.log /var/log/messages /var/log/xen/hypervisor.log
All of these files have nothing appended.
I can fetch info from kernel debugfs, if you point me to required area,
The dom0 kernel works fine

Found the references of these in
https://lists.xenproject.org/archives/html/xen-devel/2017-02/msg03120.html
proposal to split PV, PVHVM and PVH code in kernel.
There is no mention of any change or requirement from Xen perspective. Any
other way to track this problem?

I've built a dom0 kernel 4.14 with SMP support. The dom0 kernel crashes
when I'm downloading a large file on host. It does not crash if I have
nosmp boot option on xen command line.
my .config SMP options are
[root@f6029920339a wip-kernel-4.14.78]# grep SMP .config
CONFIG_X86_64_*SMP*=y
16 matches
