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

[Sami Tolvanen]

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.
