Miller" MIME-Version: 1.0 Errors-To: intel-gfx-bounces@lists.freedesktop.org Sender: "Intel-gfx" This series of cleanups was prompted by Linus: https://lkml.org/lkml/2020/3/12/726 First, this series drop always-on CONFIG_AS_* options. Some of those options were introduced in old days. For example, the check for CONFIG_AS_CFI dates back to 2006. We raise the minimal tool versions from time to time. Currently, we require binutils 2.21 (and we even plan to bump it to 2.23). After cleaning away the old checks, as-instr calls are moved to Kconfig from Makefiles, then more Kconfig / Makefile code is cleaned up. I folded all relevanet patches into this series, as suggested by Jason A. Donenfeld. The update for v2 is quite small. I just swapped the patch order of patch 8 and 11 instead of moving comments around files, which was addressed by Nick Desaulniers. Borislav Petkov (1): Documentation/changes: Raise minimum supported binutils version to 2.23 Jason A.
