If the OOB size is not multiple of the cache line size, the ARMv7 cache operation still warns "Misaligned operation at range".

The real cache coherency problem was fixed by commit e3332e1a1a04 ("Make kmalloc'ed memory really DMA-safe"). Now it is the matter of the warning messages.

The cache ops won't happen if the address isn't aligned, so this is needed on armv7a anyway. It's not just about silencing the messages, this patch is actually required.

You are right. I was misunderstanding.

I will reword the patch description. Thanks!
