Subject: [PATCH 18/18] arm64: fpsimd: Remove <asm/fpsimdmacros.h>
Date: Thu, 21 May 2026 14:25:56 +0100 [thread overview]
Message-ID: <20260521132556.584676-19-mark.rutland@arm.com> (raw)
In-Reply-To: <20260521132556.584676-1-mark.rutland@arm.com>
We no longer need any of the remaining macros in <asm/fpsimdmacros.h>.
Remove all of it.
