Subject: [PATCH 0/3] Add version macros for clang and fix arm64 for clang <6.0

In order to build an arm64 kernel with clang <6.0, we need to work
around LLVM bug 30792 by using -mno-implicit-float instead of
-mgeneral-regs-only.

This patch set adds macros for checking clang version, and enable the
workaround only for affected compiler versions.

Greg Hackmann (1):
  arm64: use -mno-implicit-float instead of -mgeneral-regs-only

Sami Tolvanen (2):
  kbuild: add clang-version.sh
  kbuild: add cc-if-name-version and compiler-specific variants
