[PATCH 2/2] crypto: blowfish - disable AVX2 implementation

2013-06-02 Thread Jussi Kivilinna
It appears that the performance of 'vpgatherdd' is suboptimal for this kind of workload (tested on Core i5-4570) and causes blowfish-avx2 to be significantly slower than blowfish-amd64. So disable the AVX2 implementation to avoid performance regressions. Signed-off-by: Jussi Kivilinna --- crypto
