Paul E. McKenney 89b4cd4b9e rcu: Print stall-warning NMI dyntick state in hexadecimal
The ->dynticks_nmi_nesting field records the nesting depth of both
interrupt and NMI handlers.  Because the kernel can enter interrupts
and never leave them (and vice versa) and because NMIs can interrupt
manipulation of the ->dynticks_nmi_nesting field, the values in this
field must be both chosen and maniupated very carefully.  As a result,
although the value is zero when the corresponding CPU is executing
neither an interrupt nor an NMI handler, it is 4,611,686,018,427,387,906
on 64-bit systems when there is a single level of interrupt/NMI handling
in progress.

This number is difficult to remember and interpret, so this commit
switches the output to hexadecimal, resulting in the much nicer
0x4000000000000002.

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
