[PATCH v4] x86, crypto: ported aes-ni implementation to x86

2010-11-11 Thread Mathias Krause
The AES-NI instructions are also available in legacy mode so the 32-bit architecture may profit from those, too. To illustrate the performance gain here's a short summary of a dm-crypt speed test on a Core i7 M620 running at 2.67GHz comparing both assembler implementations: x86:
