From 4ebf9216e7dff0b38e350007da3b03afb15c816b Mon Sep 17 00:00:00 2001 From: Hengqi Chen Date: Wed, 8 Nov 2023 14:12:16 +0800 Subject: [PATCH] LoongArch: BPF: Support unconditional bswap instructions Add support for unconditional bswap instruction. Since LoongArch is always little-endian, just treat unconditional bswap the same as big- endian conversion.
