Summary: Discrepancy between the size of cookie decriptors

Initial Comment:
In the event_buffer.h file in the oprofile kernel code we specify
invalid and no cookies as
#define INVALID_COOKIE ~0UL
#define NO_COOKIE 0U

while in opd_cookie.h in the userspace code we specify them as
#define INVALID_COOKIE ~0LLU
#define NO_COOKIE 0LLU


On an x86_32 system this seems erroneous to me. While NO_COOKIE will
still be matched correctly I dont see how INVALID_COOKIE will work,
because the kernel will emit it as 0xffffffff
while the userspace expects 0xffffffffffffffff.
