Note, there is not a 1 to 1 with keys and places that need to be
patched.

Doing the following objdump:

  objdump -dr vmlinux | grep 'jmpq.*<trace_kmalloc' | wc -l
375

That's 375 instances of kmalloc tracepoints[*] and one key. How do you
handle this?

[*] this should be fixed, we probably should find a way to move the
tracepoint into the kmalloc functions that are not inlined.
