BugLink: https://bugs.launchpad.net/bugs/1789118

== SRU Justification ==
After an upgrade to Bionic, the bug reporter states the 32-bit kernel
does not boot under Xen PV mode.  This bug does not affect 64-bit
kernels and if fixed by mainline commit 6a92b11169a6.

== Fix ==
6a92b11169a6 ("x86/EISA: Don't probe EISA bus for Xen PV guests")

== Regression Potential ==
Low.  This commit only affects x86 kernels.  This commit has also been cc'd to upstream stable, so it has had
additional upstream review.

== Test Case ==
A test kernel was built with this patch and tested by the original bug reporter.
The bug reporter states the test kernel resolved the bug.

Commit 6a92b11169a6 is also needed in cosmic.  The commit is in mainline
as of v4.19-rc4 and has been cc'd to stable.  However, it has not landed
in cosmic as of yet.

Applied to bionic/master-next. Thanks.

Also needed in Cosmic (mentioned in follow-up) which might be easy to miss.

Cosmic already got this from upstream stable.

Already applied to cosmic as part of 4.18.10.

Thanks.
