This series introduces infrastructure allowing compiler diagnostics to

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 master as of 9215310cf13b ("Merge
git://git.kernel.org/pub/scm/linux/kernel/git/davem/net").
Sorry I dropped the ball on this earlier, and thanks a lot for picking
it up again! From what I can tell, your version addresses all issues
I was aware of, so we should merge that.
