Is there a reason the init code lives in a different file than the
implementations? It seems to me all symbols could be static if the init code
lived in the same file as the implementation. This isn't a big deal, just
wondering.
Shivraj:- Yes, the files can be merged, we just followed the tradition as done
by other platforms.

Please split this file in 3, one for loopfilter, one for MC and one for
idct-related stuff. I agree the x86 code is a bad example in this respect, but
it's a good idea to improve this going forward.
Shivraj:-Incorporated changes accordingly.
+void ff_put_vp8_epel4_h4_msa(uint8_t *dst, ptrdiff_t dst_stride,
+ uint8_t *src, ptrdiff_t src_stride,
+ int height, int mx, int my)

+ const int8_t *filter = subpel_filters_msa[mx - 1];
+
+ if (2 == height) {
+ common_hz_4t_4x2_msa(src, src_stride, dst, dst_stride, filter);
Is this ever true? I don't think blocksize goes below 4 in either dimension,
ever.

Same.

Is this ever true? My impression was blocksize could ever only be a power of
two (4, 8, 16) in vp8.
+ } else if (0 == height % 2) {
Same as above, blocksize should never be 2. I don't think this code ever
executes.

Same as above.
Shivraj:- All cases of height 2, 6, 12 are removed.
The remainder of the patch looks OK to me.
