Subject: [PATCH 2/2] kmemtrace: Use tracepoints instead of markers.

kmemtrace now uses tracepoints instead of markers. We no longer need to
use format specifiers. Also dropped kmemtrace_mark_alloc_node(), since
it's easy to pass -1 as the NUMA node without providing a needless and
long-named variant of the same function.

Signed-off-by: Eduard - Gabriel Munteanu <eduard.munteanu@...ux360.ro>
