ossl_hash_context was increased (244 -> 2048bytes) for arm
Since this isn't an Armada38x specific change I believe that it should be applied to all kernel configs.
IMHO we should modify the default value in arm/include/param.h.
Another thing is that 8 pages might be more than needed, e.g. amd64 defaults to 4/6 depending on whether KASAN is enabled.
Also as mw mentioned the commit message should contain a verbose explanation why we need to increase the kernel stack size.
