From 12a0b52ebb5101f9bb436a764c1ebf3d730db528 Mon Sep 17 00:00:00 2001 From: Alyssa Ross Date: Thu, 1 Apr 2021 17:30:29 +0000 Subject: linux: enable Xen everywhere it can be I don't think there's any reason to have a seperate kernel variant because of this, with all the maintenance burden that imposes. Debian and Fedora both enable all these options on their normal kernels. Alias the Linux Xen attributes, so this change should be seemless for people who were using the Xen kernels up to now. All the Xen options are marked as optional anyway, so it should be fine to try to enable them on non-x86 platforms as well. Cherry-picking this for Spectrum because PVH is cloud-hypervisor's preferred boot entry point on x86, and it'll complain if our kernel doesn't support it.
