I'd really just rather do %016lx *everywhere* than sprinkle the PKEY_REG_FMTs around.
Does lx work with u32 without warnings?
Either way, I'd be happy to just make the x86 one u64 to make the whole thing look more sane,
It's userspace so you don't get u64, you only get __u64.
And then you'll hit the fact that by default __u64 is unsigned long on powerpc and unsigned long long on x86, meaning you still can't use the same printf specifier.
To avoid that you should define __SANE_USERSPACE_TYPES__ before including any headers, and then you'll get unsigned long long for __u64 everywhere and you can just use %llx.
