I dug into this a bit. To quote asm/types.h: /* * This is here because we used to use l64 for 64bit powerpc * and we don't want to impact user mode with our change to ll64 * in the kernel. */ #if defined(__powerpc64__) && !defined(__KERNEL__) # include <asm-generic/int-l64.h> #else # include <asm-generic/int-ll64.h> #endif So ppc64 kernel space uses ll64 and userspace uses l64. This means __u64 is a long for ppc64 but a long long for x86_64. The format errors occurs rightly because a ull is being printed from a ul variable. This will happen to work but its messy.
