Linus Torvalds 08d72bd299 A small set of updates for CPU hotplug:
- Prevent stale CPU hotplug state in the cpu_down() path which
     was detected by stress testing the sysfs interface
 
   - Ensure that the target CPU hotplug state for the boot CPU is
     CPUHP_ONLINE instead of the compile time init value CPUHP_OFFLINE.
 
   - Switch back to the original behaviour of warning when a CPU hotplug
     callback in the DYING/STARTING section returns an error code. Otherwise
     a buggy callback can leave the CPUs in an non recoverable state.

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.
