| Message-ID | <qyKut-8c2-9@gated-at.bofh.it> |
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.
