It wouldn't be just about warnings if somebody uses current kernel headers for /usr/include/linux and /usr/include/asm. Think about C++ name mangling, there it matters a lot of a type is long long or just long, although they are the same size.
It is true that (hopefully) most of the distributions use separate modified kernel headers and glibc uses only very few kernel headers in its headers, but there are certainly many apps in the wild who #include <linux/*> or #include <asm/*> and I'm afraid still some people use newest kernel headers for userland stuff.
So if you want to change that, I'd suggest to #ifdef __KERNEL__ typedef unsigned long long __u64; #else typedef unsigned long __u64; /* Provided it has been defined that way before */ #endif
