We won't if we ensure that a structure with sizeof() >= 128 is aligned
to 128.

There is no direct CRYPTO_MINALIGN use for any extra padding AFAICT.
There is an indirect use via __alignof__(ctx) like in
crypto_tfm_ctx_alignment() but IIUC in that case CRYPTO_MINALIGN is a
statement of what you want rather than what you get from kmalloc(). So
if you want 128 alignment of tfm->__crt_ctx, you should say so by either
changing the attribute to __aligned(ARCH_DMA_MINALIGN) or keeping
CRYPTO_MINALIGN as 128.
There is the union padding that Ard suggested but I don't think it buys
us much, the __aligned(ARCH_DMA_MINALIGN) gives you the padding and the
kmalloc() rules the alignment (subject to removing kmalloc-192). The
code that allocates these would need to place the structure aligned
anyway, irrespective of whether we use the padding or the
__aligned(ARCH_DMA_MINALIGN).

I disagree on the cra_alignmask intention here, though I may be wrong as
I did not write the code. Yes, you could make it ARCH_DMA_MINALIGN
everywhere but IMHO that's not what it is supposed to do. The driver
only knows about the bus master alignment requirements (typically
smaller than a cache line) while the architecture-defined
ARCH_DMA_MINALIGN cares about the non-coherent DMA requirements.

I'm not actually increasing CRYPTO_MINALIGN, just trying to keep it as
the current value of 128 for arm64.
