Once we wrap asm/types.h, it will also replace the glibc asm/types.h, not only the kernel one. This results in build errors on some machines. Drop this wrapper and do its work from linux/types.h wrapper, also the glibc asm/types.h can already handle most of the type definition it was doing (typedef __u64, __u32, etc...). Todo: Check the others asm/*.h wrappers to prevent from other conflicts.
