The check cpu_needs_post_dma_flush() in mips_dma_sync_sg_for_cpu() and the check !plat_device_is_coherent() in mips_dma_sync_sg_for_device() can be moved outside the for loop. As a side effect, this also avoids a GCC bug that caused kernel compile to fail with the error: arch/mips/mm/dma-default.c: In function 'mips_dma_sync_sg_for_cpu': arch/mips/mm/dma-default.c:316:1: internal compiler error: in add_insn_before, at emit-rtl.c:3852 This gcc failure is seen in Code Sourcery toolchains [e.g. gcc version 4.7.2 (Sourcery CodeBench Lite 2012.09-99)] after commit "MIPS: Optimize current_cpu_type() for better code."
