Subject: [PATCH v2 3/3] arm64: Kconfig: drop KAISER reference from KPTI option description
Date: Mon, 27 Nov 2023 13:00:53 +0100 [thread overview]
Message-ID: <20231127120049.2258650-8-ardb@google.com> (raw)
In-Reply-To: <20231127120049.2258650-5-ardb@google.com>
From: Ard Biesheuvel <ardb@kernel.org>
KAISER is a reference to the KASLR hardening technique that already
existed before Meltdown happened, and by now, it is sufficiently obscure
that mentioning it does not actually clarify anything. So remove this
reference, and replace it with KPTI.
