Subject: [PATCH v6 01/13] x86/bugs: Rename GDS_FORCE_MITIGATION to MITIGATION_GDS_FORCE
Date: Tue, 21 Nov 2023 08:07:28 -0800	[thread overview]
Message-ID: <20231121160740.1249350-2-leitao@debian.org> (raw)
In-Reply-To: <20231121160740.1249350-1-leitao@debian.org>

CPU mitigations config entries are inconsistent, and names are hard to
related[1]. There are concrete benefits for both users and developers of
having all the mitigation config options living in the same config
namespace.

The mitigation options should have consistency and start with
MITIGATION.

Rename the Kconfig entry from GDS_FORCE_MITIGATION to
MITIGATION_GDS_FORCE.
