OK just to be on safe side I noticed memblock_virt_alloc() and memblock_virt_alloc_nopanic() allow passing an explicit alignment requirement, traced back the orignal code with no good reason to not use the LOG_ALIGN, so I think using that would be the safest thing to do. Will roll that into the first patch, curious if the folks that ran into the alignment issues on ARM could reproduce an align barf without this on some situations, perhaps not because of the power of 2 thing and since the min value for LOG_BUF_SHIFT is 12.
