Subject: [PATCH 7/8] lib/raid/xor: x86: Remove redundant X86_FEATURE_OSXSAVE check
Date: Thu, 25 Jun 2026 21:37:30 -0700 [thread overview]
Message-ID: <20260626043731.319287-8-ebiggers@kernel.org> (raw)
In-Reply-To: <20260626043731.319287-1-ebiggers@kernel.org>
X86_FEATURE_AVX implies X86_FEATURE_OSXSAVE already.
