This series introduces infrastructure allowing compiler diagnostics to be disabled or their severity modified for specific pieces of code, with suitable abstractions to prevent that code from becoming tied to a specific compiler. This infrastructure is then used to disable the -Wattribute-alias warning around syscall definitions, which rely on type mismatches to sanitize arguments. Finally PowerPC-specific #pragma's are removed now that the generic code is handling this. The series takes Arnd's RFC patches & addresses the review comments they received. The most notable effect of this series to to avoid warnings & build failures caused by -Wattribute-alias when compiling the kernel with GCC 8. Applies cleanly atop v4.18-rc1.
