In-Reply-To: <20210811085842.2511545-2-jean-philippe@linaro.org> (Jean-Philippe Brucker's message of "Wed, 11 Aug 2021 10:58:44 +0200")
Michael & Marcel, this patch fixes a bug that became a regression when
the fix missed 6.1. It's been stuck on the list since August. Please
have a look, and if it's good, get it merged. I just asked the arm/virt
maintainer to do the same for PATCH 1.
