+Subject: [PATCH] MIPS: partially inline dma ops
+
+Several DMA ops are no-op on many platforms, and the indirection through
+the mips_dma_map_ops function table is causing the compiler to emit
+unnecessary code.
+
+Inlining visibly improves network performance in my tests (on a 24Kc
+based system), and also slightly reduces code size of a few drivers.
