Subject: [PULL 15/26] ppc/ppc405: Introduce a store helper for SPR_40x_PID
Date: Tue, 4 Jan 2022 08:31:10 +0100 [thread overview]
Message-ID: <20220104073121.3784280-16-clg@kaod.org> (raw)
In-Reply-To: <20220104073121.3784280-1-clg@kaod.org>
The PID SPR of the 405 CPU contains the translation ID of the TLB
which is a 8-bit field. Enforce the mask with a store helper.
