kernel: add patch header and missing part in 132-mips_inline_dma_ops.patch again
The select SYS_HAS_DMA_OPS in CPU_CAVIUM_OCTEON was from the kernel patch in 3.13, but it is only included in kernel 3.14 and not in 3.13 and 3.18, add it again. Thank you swalker for spotting this. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> SVN-Revision: 43134

+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.
