@Breno since the missing commits are only for improved reporting of
vulnerability status, does IBM consider them to be needed for Ubuntu
14.04's 3.13 kernel? (Ubuntu 17.10's 4.13 kernel will go EoL soon so it
probably won't receive the changes)

Thanks! I just submitted the pull request for bionic. We're too late for
the current SRU cycle for the stable releases (17.10, 16.04 LTS, and
14.04 LTS) so we'll have to pick them up in the next SRU cycle.
Note that I didn't include the section mismatch warning since it hadn't

Hi Tyler,
Yes, we need to backport this patchset to all the current supported
kernel. Since most of the supported kernel contains the whole RFI infra
structure, I do not expect it to be hard. If you need help, I can find
someone to help on the backport.
Regarding the problem you are facing, I
@Breno in addition to the question above about which releases you're
requesting, I have a new question about section mismatch warnings that
the first patchset introduces:
WARNING: vmlinux.o(.text+0x8): Section mismatch in reference from the
function setup_rfi_flush() to the function
@Breno ack, I'll look at bringing them in, as well.
Do you want these changes (both patch sets) in 18.04 only or are you
asking for them to be in 17.10, 16.04, and 14.04, as well?

Hey Tyler,
I thought these patches were in already, so, let's bring them also.
Backporting without these fixes might not be easy to accomplish, and
nothing something we want to keep for the whole 18.04 life. Let's try to
be as near as possible to upstream and bring the required patches in.
@Breno the changes in this patch set touch some of the same areas of
code:
http://patchwork.ozlabs.org/project/linuxppc-
dev/list/?series=33861=*
[v3,5/5] rfi-flush: Call setup_rfi_flush() after LPM migration
[v3,4/5] rfi-flush: Differentiate enabled and patched flush types
