[v2] SEV re-initialization fixes

[PATCH v2 0/4] SEV re-initialization fixes

Posted by Tycho Andersen 1 month, 1 week ago

From: "Tycho Andersen (AMD)" <tycho@kernel.org>

Here is a v2 of the HSAVE_PA clearing fixes. Changes are:

* return ENODEV instead EINVAL for the re-init cases
* note ABI breakage in patch 3's commit log
* CC stable on all the patches

v1 is here: https://lore.kernel.org/all/20260427161507.32686-1-tycho@kernel.org/

Thanks,

Tycho
