crypto: ghash-clmulni-intel - use C implementation for setkey()
The GHASH setkey() function uses SSE registers but fails to call kernel_fpu_begin()/kernel_fpu_end(). Instead of adding these calls, and then having to deal with the restriction that they cannot be called from interrupt context, move the setkey() implementation to the C domain. Note that setkey() does not use any particular SSE features and is not expected to become a performance bottleneck. Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Acked-by: H.
