KVM/arm64 fixes for 6.8, take #2
Marc Zyngier
maintainerHi Paolo,
Another week, another very small pull request. This time, the bug is irritating enough that I want it fixed and backported right away. It has only been found by inspection (thanks Will!), but once you've seen it, you can unsee it.
If you haven't pulled the previous tag [1], you'll get both for free.
Please pull,
M.
