JFYI, I am finding the vanilla defconfig build broken for arm64:

In addition, the reason I was testing this was because Linus' master 
(d6f9469a03d8 Merge tag 'erofs-for-5.8-rc1' of 
git://git.kernel.org/pub/scm/linux/kernel/git/xiang/erofs) was crashing:

I'll check that when I get a chance. Maybe all just transient.
