From: Arnd Bergmann Date: Wed, 16 Apr 2014 07:54:02 +0000 (+0200) Subject: ARM: mohawk: allow building with MMU disabled X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=0f67b876092ae4fabe6ff81a92c785a69edb0022;p=deliverable%2Flinux.git ARM: mohawk: allow building with MMU disabled 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.
