Petr Mladek 34de49d097 kallsyms/bpf: rename __bpf_address_lookup() to bpf_address_lookup() 
[ Upstream commit cd6735896d ]

bpf_address_lookup() has been used only in kallsyms_lookup_buildid().  It
was supposed to set @modname and @modbuildid when the symbol was in a
module.

But it always just cleared @modname because BPF symbols were never in a
module.  And it did not clear @modbuildid because the pointer was not
passed.

The wrapper is no longer needed.  Both @modname and @modbuildid are now
always initialized to NULL in kallsyms_lookup_buildid().

Remove the wrapper and rename __bpf_address_lookup() to
bpf_address_lookup() because this variant is used everywhere.

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 reStructuredText 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.
