Subject: [PATCH 1/2] lib/raid6: Switch to Linux's NEON intrinsics header
Date: Wed,  9 Sep 2026 18:33:21 +0200	[thread overview]
Message-ID: <20260909163319.2116279-5-ardb+git@google.com> (raw)
In-Reply-To: <20260909163319.2116279-4-ardb+git@google.com>

From: Ard Biesheuvel <ardb@kernel.org>

Including arm_neon.h directly requires workarounds in the types.h header
that are ugly and should only be applied when actually building NEON
code.

ARM and arm64 both have a asm/neon-intrinsics.h header that applies the
same workarounds, but without propagating them to all other C files. So
include that instead.

This will allow those type hacks to be dropped from the ARM tree.
