From e55318c84f199d6056a0bcd98bc4612d01ccfe80 Mon Sep 17 00:00:00 2001 From: Ondrej Mosnáček Date: Sun, 2 Apr 2017 21:19:14 +0200 Subject: crypto: gf128mul - switch gf128mul_x_ble to le128 Currently, gf128mul_x_ble works with pointers to be128, even though it actually interprets the words as little-endian. Consequently, it uses cpu_to_le64/le64_to_cpu on fields of type __be64, which is incorrect. This patch fixes that by changing the function to accept pointers to le128 and updating all users accordingly.
