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.

To make this possible it is necessary to isolate from the kernel headers the common parts that are strictly necessary to build the library. Introduce processor.h to contain all the processor specific functions that are suitable for vDSO inclusion.
