[PATCH 5.5 181/367] crypto: arm64/ghash-neon - bump priority to 150

From: Greg Kroah-Hartman
Date: Mon Feb 10 2020 - 08:01:52 EST


From: Ard Biesheuvel <ardb@xxxxxxxxxx>

commit 5441c6507bc84166e9227e9370a56c57ba13794a upstream.

The SIMD based GHASH implementation for arm64 is typically much faster
than the generic one, and doesn't use any lookup tables, so it is
clearly preferred when available. So bump the priority to reflect that.
