From: Julien Thierry Date: Wed, 3 Mar 2021 17:05:32 +0000 (+0100) Subject: arm64: Move instruction encoder/decoder under lib/ X-Git-Tag: v5.14-rc1~167^2~9^2~7 X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=72fd723694b6f4f1d1f19f673fb93801d7d1a0e8;p=users%2Fhch%2Fmisc.git 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.
