Fix the problem "kmemtrace: fix printk format warnings" attempted to fix,
but resulted in marker-probe format mismatch warnings. Instead of carrying
size_t into probes, we get rid of it by casting to unsigned long, just as
we did with gfp_t.
This way, we don't need to change marker format strings and we don't have
to rely on other format specifiers like "%zu", making for consistent use
of more generic data types (since there are no format specifiers for
gfp_t, for example).

kmemtrace provides tracing for slab allocator functions, such as kmalloc,
kfree, kmem_cache_alloc, kmem_cache_free etc.. Collected data is then fed
to the userspace application in order to analyse allocation hotspots,
internal fragmentation and so on, making it possible to see how well an
allocator performs, as well as debug and profile kernel code.
