Subject: [PATCH RFC v2 02/29] x86: Create CONFIG_MITIGATION_ADDRESS_SPACE_ISOLATION
Date: Fri, 10 Jan 2025 18:40:28 +0000 [thread overview]
Message-ID: <20250110-asi-rfc-v2-v2-2-8419288bc805@google.com> (raw)
In-Reply-To: <20250110-asi-rfc-v2-v2-0-8419288bc805@google.com>
Currently a nop config. Keeping as a separate commit for easy review of
the boring bits. Later commits will use and enable this new config.
This config is only added for non-UML x86_64 as other architectures do
not yet have pending implementations. It also has somewhat artificial
dependencies on !PARAVIRT and !KASAN which are explained in the Kconfig
file.
