@Khaled these debdiffs look good enough for me to sponsor. I made one
superficial change by removing the "## " prefix from the patch tags
lines. However, there were two important changes required for the Xenial
debdiff. The version wasn't correct (I changed it to
2.8.0-1ubuntu1~16.04.5 instead of 2
@Khaled after giving it a little more thought, I think these changes
might be needed in bionic in the situation that an artful user is
upgrading to bionic or when a xenial hwe user is upgrading to bionic. I
think that if the lttng-modules-dkms binary package is upgraded to the
bionic package bionic
Adding equivalent fix for xenial-hwe

** Description changed:
+ [Impact]
+
+ * The 4.13.0-38 artful kernel included a change (backported from 4.15)
+ that modifies the definition of kvm_mmio(). This breaks the lttng-
+ modules-dkms package because it is using the old (<4.15) definition.
+
+ * lttng-modules-dkms already has a list
4.13.0-38 introduced a new definition of kvm_mmio() that is backported
from 4.15. There's already a list of excepted kernel versions for which
the new (4.15) definition should be used. I added ubuntu 4.13.0-38-and-
later kernels to that list.
Tested by first successfully building lttng-modules-dkm
