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 plan to bump it to 2.23 for v5.7-rc1). After cleaning away the old checks, as-instr calls are moved to Kconfig from Makefiles. (patch 11) This allows more Kconfig / Makefile cleanups. Patch 12 is complex, but I double-checked it does the equivalent. Patch 14 bumps the binutils version to 2.23, and patch 15 removes more CONFIG_AS_* options. I folded all relevanet patches into this series, as suggested by Jason A. Donenfeld. If x86 maintainers take care of this series, that's good. If it is OK to queue this up to Kbuild tree, I will send a pull request to Linus. Thank you. Borislav Petkov (1): Documentation/changes: Raise minimum supported binutils version to 2.23 Jason A.
