Dmitry Safonov c7a1a092d3 perf symbols: Use (long) for iterator for bfd symbols
[ Upstream commit 96de68fff5ded8833bf5832658cb43c54f86ff6c ]

GCC (GCC) 8.4.0 20200304 fails to build perf with:
: util/symbol.c: In function 'dso__load_bfd_symbols':
: util/symbol.c:1626:16: error: comparison of integer expressions of different signednes
:   for (i = 0; i < symbols_count; ++i) {
:                 ^
: util/symbol.c:1632:16: error: comparison of integer expressions of different signednes
:    while (i + 1 < symbols_count &&
:                 ^
: util/symbol.c:1637:13: error: comparison of integer expressions of different signednes
:    if (i + 1 < symbols_count &&
:              ^
: cc1: all warnings being treated as errors

It's unlikely that the symtable will be that big, but the fix is an
oneliner and as perf has CORE_CFLAGS += -Wextra, which makes build to
fail together with CORE_CFLAGS += -Werror

Fixes: eac9a4342e ("perf symbols: Try reading the symbol table with libbfd")

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.
