Subject: [PATCH v2 1/5] target/hppa: Add missing PL1 and PL2 privilege levels
Date: Fri, 25 Aug 2023 08:56:34 +0200 [thread overview]
Message-ID: <20230825065638.7262-2-deller@kernel.org> (raw)
In-Reply-To: <20230825065638.7262-1-deller@kernel.org>
From: Helge Deller <deller@gmx.de>
The hppa CPU has 4 privilege levels (0-3).
Mention the missing PL1 and PL2 levels, although the Linux kernel
uses only 0 (KERNEL) and 3 (USER). Not sure about HP-UX.
