Alexei Starovoitov 1336c66247 bpf: Clear per_cpu pointers during bpf_prog_realloc

Fixes: 700d4796ef ("bpf: Optimize program stats")
Fixes: ca06f55b90 ("bpf: Add per-program recursion prevention mechanism")

README 

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.
