Kobe Wu 9156e54576 locking/lockdep: increase size of counters for lockdep statistics
When system has been running for a long time, signed integer
counters are not enough for some lockdep statistics. Using
unsigned long counters can satisfy the requirement. Besides,
most of lockdep statistics are unsigned. It is better to use
unsigned int instead of int.

Remove unused variables.
- max_recursion_depth
- nr_cyclic_check_recursions
- nr_find_usage_forwards_recursions
- nr_find_usage_backwards_recursions

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.
