Subject: [PATCH] vdso: Replace __ASSEMBLY__ with __ASSEMBLER__ in header files

While the GCC and Clang compilers already define __ASSEMBLER__
automatically when compiling assembly code, __ASSEMBLY__ is a macro that
only gets defined by the Makefiles in the kernel.

This can be very confusing when switching between userspace and kernelspace
coding, or when dealing with uapi headers that rather should use
__ASSEMBLER__ instead.

So standardize now on the __ASSEMBLER__ macro that is provided by the
compilers.
