Comment 5 for bug 1763468

Thanks Greg for taking a look with me.
We unfortunately can't rely on kernel 4.15 due to the fact that the virt stack in 18.04 will be made available to Xenial via the Ubuntu Cloud Archive [1].

So this could run on hosts as much back as 4.4
With that said we would still need patches -1 and -4.

You said -5, -6 and -7 (plus -8 as fix) are only cleanup so those we might drop.
Due to the dependencies outlined before I kept them in the series, but I'm happy to follow your guidance on that.

And with -1, -2, -3, -4, - 9 there is not even noise on xics_max_server_number.

I made a respin of the build in the ppa [2] with that.
Please verify if that suits your needs for:
- this bug 1763468
- other current ppc bug 1762854
