[RFC PATCH 0/2] ARM: kernel mode NEON in softirq context

[ard.biesheuvel@linaro.org (Ard Biesheuvel)]

Patch #1 in this series adds support for using the NEON in kernel mode
while executing in softirq context. By allowing this, subsystems that
perform non-trivial crypto in softirq context (such as CCMP in the
mac80211 layer) can use algorithms such as the AES-CCM driver in
patch #2, which is 13x faster than the generic CCM driver.

Ard Biesheuvel (2):
  ARM: vfp - allow kernel mode NEON in softirq context
  crypto: arm/aes - add CCM driver using ARMv8 Crypto Extensions
