Subject: [PATCH v2 0/4] SEV re-initialization fixes
Date: Mon,  4 May 2026 10:51:43 -0600	[thread overview]
Message-ID: <20260504165147.1615643-1-tycho@kernel.org> (raw)

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
