The global 'tmpbuf' variable in part_iso triggers invalid cache alignment warnings when not being aligned to ARCH_DMA_MINALIGN:

The quick fix here is to align the global 'tmpbuf' variable using DEFINE_CACHE_ALIGN_BUFFER. A real fix would be to change part_iso.c to use function local buffers defined with ALLOC_CACHE_ALIGN_BUFFER.
Can we try and do the real fix please? The merge window isn't even closed just yet, thanks!
