[ Upstream commit dce088ab0d51ae3b14fb2bd608e9c649aadfe5dc ]
Commit 11e9734bcb ("mm/slab_common: unify NUMA and UMA version of
tracepoints") adds the field "node" into the tracepoints 'kmalloc' and
'kmem_cache_alloc', so this patch modifies the event process function to
support the field "node".
If field "node" is detected by checking function evsel__field(), it
stats the cross allocation.
When the "node" value is NUMA_NO_NODE (-1), it means the memory can be
allocated from any memory node, in this case, we don't account it as a
cross allocation.
Fixes: 11e9734bcb ("mm/slab_common: unify NUMA and UMA version of tracepoints")
