From 72fd723694b6f4f1d1f19f673fb93801d7d1a0e8 Mon Sep 17 00:00:00 2001 From: Julien Thierry Date: Wed, 3 Mar 2021 18:05:32 +0100 Subject: [PATCH] arm64: Move instruction encoder/decoder under lib/ Aarch64 instruction set encoding and decoding logic can prove useful for some features/tools both part of the kernel and outside the kernel. Isolate the function dealing only with encoding/decoding instructions, with minimal dependency on kernel utilities in order to be able to reuse that code. Code was only moved, no code should have been added, removed nor modifier.
