Applied over current git kernel, boots on my sparc64 LDOM (sunvdc block driver which uses vio). Linux ttip 5.11.0-10201-gc03c21ba6f4e-dirty #189 SMP Wed Feb 24 13:48:37 MSK 2021 sparc64 GNU/Linux boot logs (and kernel config) on [1] for "5.11.0-10201-gc03c21ba6f4e-dirty". Up to you to add "tested-by". Thanks. 1. https://github.com/mator/sparc64-dmesg PS: going to check with ppc64 later as well on LPAR (uses vio).
