Subject: [PATCH v2 0/1] x86/boot: save fields explicitly, zero out everything else
Date: Tue, 30 Jul 2019 22:46:26 -0700 [thread overview]
Message-ID: <20190731054627.5627-1-jhubbard@nvidia.com> (raw)
From: John Hubbard <jhubbard@nvidia.com>
Hi,
This uses the "save each field explicitly" approach that we discussed
during the first review [1]. As in [1], this is motivated by a desire
to clear the compiler warnings when building with gcc 9.
This is difficult to properly test. I've done a basic boot test, but
if there are actually errors in which items get zeroed or not, I don't
have a good test to uncover that.
