I cannot reproduce that issue. What's the underlying hardware machine?

brand: Genuine Intel(R) CPU 000 @ 2.27GHz
model: Westmere-EX
memory: 256G
nr_node: 4
nr_cpu: 80

Ok. I'll try to find something similar. Can please you rerun that test on
that particular configuration with the updated branch?

     git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git WIP.x86/ipi

I have tested commit e0b179bc1a ("x86/apic/x2apic: Add conditional IPI
shorthands support"), the problem is still exist.

the head of that branch is:

       4f3f6d6a7f8e ("x86/apic/x2apic: Add conditional IPI shorthands support")

This is WIP and force pushed. There are no incremental changes. Could you
please check again?

The problem is still exist.

Best Regards,
Rong Chen

Thanks,
