Subject: [PATCH v3 06/10] x86: drop SWIOTLB for PAE
Date: Wed, 26 Feb 2025 22:37:10 +0100 [thread overview]
Message-ID: <20250226213714.4040853-7-arnd@kernel.org> (raw)
In-Reply-To: <20250226213714.4040853-1-arnd@kernel.org>
From: Arnd Bergmann <arnd@arndb.de>
Since kernels with and without CONFIG_X86_PAE are now limited
to the low 4GB of physical address space, there is no need to
use swiotlb any more, so stop selecting this.

PAE is required for NX support, and furthermore enables
larger swapspace support for non-overcommit purposes. It
