From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: From: Arnd Bergmann To: linux-arm-kernel@lists.infradead.org Cc: linux-clk@vger.kernel.org, linux-kernel@vger.kernel.org, Eric Miao , Haojian Zhuang , Michael Turquette , Stephen Boyd , Arnd Bergmann Subject: [PATCH 3/7] ARM: mohawk: allow building with MMU disabled Date: Wed, 25 Nov 2015 16:37:51 +0100 Message-Id: <1448465875-435039-4-git-send-email-arnd@arndb.de> In-Reply-To: <1448465875-435039-1-git-send-email-arnd@arndb.de> References: <1448465875-435039-1-git-send-email-arnd@arndb.de> List-ID: It is in principle possible to build an MMP kernel for the mohawk CPU with the MMU code disabled, except for one simple build error: proc-mohawk.S:345: Error: invalid operands (*UND* and *UND* sections) for `|' proc-mohawk.S:345: Error: invalid operands (*ABS* and *UND* sections) for `|' proc-mohawk.S:345: Error: invalid operands (*UND* and *UND* sections) for `|' proc-mohawk.S:345: Error: invalid operands (*UND* and *UND* sections) for `|' proc-mohawk.S:345: Error: undefined symbol L_PTE_USER used as an immediate value This patch changes the proc-mohawk code to do the same as the other CPUs and not try to actually do anything for the cpu_mohawk_set_pte_ext function, which won't be used anyway.
