Remove them to free up the namespace. There's still a reference to u128 in drivers/crypto/vmx/ghash.c. But, it's only dereferenced by assembly code, so it should keep working even if u128 gets redefined to a native int. I don't speak PowerPC, so I'm not sure what the "correct" type is there. - Eric

Per git-grep u128_xor() and its related struct u128 are unused except to implement {be,le}128_xor(). Remove them to free up the namespace. Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org> --- include/crypto/b128ops.h | 14 +++----------- 1 file changed, 3 insertions(+), 11 deletions(-)
