[ Upstream commitdce088ab0d] Commit11e9734bcb("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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
