Subject: [PATCH 1/2] arm64: Sort vendor-specific errata
Date:   Thu, 16 Apr 2020 13:56:57 +0200
Message-Id: <20200416115658.20406-2-geert+renesas@glider.be>
In-Reply-To: <20200416115658.20406-1-geert+renesas@glider.be>
References: <20200416115658.20406-1-geert+renesas@glider.be>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Sort configuration options for vendor-specific errata by vendor, to
increase uniformity.
Move ARM64_WORKAROUND_REPEAT_TLBI up, as it is also selected by
ARM64_ERRATUM_1286807.
