Just a heads up it seems this patch is causing some instability with crypto self
tests on OpenRISC when using a PREEMPT kernel (no SMP).
This was reported by Jason A. Donenfeld as it came up in wireguard testing.
I am trying to figure out if this is an OpenRISC PREEMPT issue or something
else.
That patch is so simple that I can't imagine how could it break the
curve25519 test. Are you sure that you bisected it correctly?
Can you provide a test cases for hex_to_bin()?
BTW we use exactly the same code from Mikulas in cryptsetup now (actually the report
was initiated from here :) and I added some tests for this code,
you can probably adapt it (we just use generic wrapper around it):

(it calls this: https://gitlab.com/cryptsetup/cryptsetup/-/commit/ff14c17de794fe85299d90e34e12a677e6148b71 )
I do not have OpenRISC available, but it would be interesting to run cryptsetup/tests/vectors-test there...
