Please set the kernel options

CONFIG_CRYPTO_AES_ARM=m
CONFIG_CRYPTO_SHA1_ARM=m

These enable implementations of the algorithms that use ARM assembler and are quite a bit faster than the stock C versions. They accelerated encryption-heavy tasks by factor 1.5 in my short tests.

SHA1_ARM was already in. I've added AES_ARM too.
Should be in latest rpi-update kernel.

That was fast, thanks! Just ran rpi-update and got it, works as expected.

SHA1_ARM wasn't in a week ago (when I last updated), but was added 5 days ago in raspberrypi/firmware@452637c3 - should have updated right before posting the issue, sorry.

Anyway, issue can be closed in my opinion.
