Hey Christian, Stefan,

Here's a MR [1] to add support for zstd compression to Focal's Xen 4.11.

It's a straightforward backport from Xen 4.15 (just too many additions
to implement zstd, and hook its functions in kernel decompression code).

The test packages in ppa:mfo/lp1956166 [2] can successfully boot a 5.15
kernel in Dom0, DomU/PV, and DomU/HVM (unchanged) modes, and continue to
boot the 5.4 kernel successfully (some level of 'no regression' testing).

All test steps are provided in the next comment.

Could you please review / provide feedback to the MR?

Thanks!
Mauricio
