This series makes the "aes-fixed-time" and "aes-arm" implementations of
AES more resistant to cache-timing attacks.

Note that even after these changes, the implementations still aren't
necessarily guaranteed to be constant-time; see
https://cr.yp.to/antiforgery/cachetiming-20050414.pdf for a discussion
of the many difficulties involved in writing truly constant-time AES
software.  But it's valuable to make such attacks more difficult.

Eric Biggers (2):
  crypto: aes_ti - disable interrupts while accessing S-box
  crypto: arm/aes - add some hardening against cache-timing attacks
