Hello!

An update to this post with oss-security CC'ed.

I have tested these patches against 5.14 but it seems the problem [1] still remains for me
for big-endian guests. I built a patched kernel yesterday, rebooted the KVM server and let
the build daemons do their work over night.

I have done thorough testing and I'm no longer seeing the problem with the patched kernel.

I am not sure what triggered my previous crash but I don't think it's related to this
particular bug. I will keep monitoring the server in any case and open a new bug report
in case I'm running into similar issues.

Thanks,
Adrian
