From c99d30706043481a1d631bbd9c7a4b70fe002a2b Mon Sep 17 00:00:00 2001 From: Eric Biggers Date: Fri, 17 Oct 2025 21:31:01 -0700 Subject: [PATCH] byteorder: Add le64_to_cpu_array() and cpu_to_le64_array() Add le64_to_cpu_array() and cpu_to_le64_array(). These mirror the corresponding 32-bit functions. These will be used by the BLAKE2b code.
