When I build an arm64 kernel with upstream v5.8 (make bindeb-pkg) on 
sid, the built kernel can't load any modules -- lsmod output is empty, 
modprobe-ing any module fails with "Exec format error". I think it might 
be related to GCC 10, because I had also tried building the Debian 
package when you just updated it to v5.8 (eebcb7ad) and got a fully 
working kernel then (but the overall build failed due to udebs which you 
already fixed).

I also ran into a GCC issue other people already reported [1][2] while 
building the current version of the master branch (26a6ecc2) for arm64 
(I wanted to check if it could load modules correctly, I will send an 
update if I can manage to test that).
