Subject: [RFC PATCH v3 4/4] arm64: neon: Add backwards compatibility kernel_neon_begin_partial()
Date: Thu, 25 May 2017 19:25:01 +0100 [thread overview]
Message-ID: <1495736721-20985-5-git-send-email-Dave.Martin@arm.com> (raw)
In-Reply-To: <1495736721-20985-1-git-send-email-Dave.Martin@arm.com>
kernel_neon_begin_partial() is no longer available, but the
implementation of kernel_neon_begin() should be sufficient to
satisfy kernel_neon_begin_partial() callers.
Because of the changed semantics of may_use_simd() and
kernel_neon_begin() such code really needs to be ported.
In the meantime, this patch restores buildability of kernel-mode
NEON client code.
