I reported [1] to the gcc project some days ago. It has been marked as
duplicate of [2] which is not resolved yet. There are several
workarounds mentioned in [2], maybe volatile does the trick...

Do you have workaround to suppress this warning? I just hit that warning
as well…

link error.  It's the same in ubuntu 20.04. 
If you can change the OS, you can try it in ubuntu 18.04.
If not. Please use the linux kernel source in 
https://github.com/siemens/linux/ 
 

It's very easy to compile jailhouse when use the right kernel source.

This is a warning and treated as error due to -Wall.

This warning is GCC 11 specific, the code compiles with GCC 10, but
fails with GCC 11.

I looked into that a few days ago and considered that as gcc bug. In my
eyes the array boundarys are not correctly "detected" by gcc and that
might be the reason for the warning. Not sure if it was already reported
upstream to the gcc guys.
