Subject: [PATCH] x86/fpu: remove unused macros
Date:   Tue, 21 Jan 2020 16:50:11 +0800
Message-Id: <1579596611-258536-1-git-send-email-alex.shi@linux.alibaba.com>
To:     unlisted-recipients:; (no To-header on input)
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

NR_VALID_PKRU_BITS/PKRU_VALID_MASK are never used after it was
introduced. So better to remove them.
