If there is none, then rip off the kernel implementation or lobby glibc
to provide one, or make a "libunaligned.so" and distribute it etc...
but to NOT rely on the kernel header, that is bogus.

Kernel headers are totally free to use whatever macros they want in
their implementation, none of that has to be available to userland.
Also, there is no guarantee that get_unaligned() is inlined at all

Stop this crap please !
