Linus Torvalds 45365a06aa - Add support for function error injection.
- Add support for custom exception handlers, as required by BPF_PROBE_MEM.
 
 - Add support for BPF_PROBE_MEM.
 
 - Add trace events for idle enter / exit for the s390 specific idle
   implementation.
 
 - Remove unused zcore memmmap device.
 
 - Remove unused "raw view" from s390 debug feature.
 
 - AP bus + zcrypt device driver code refactoring.
 
 - Provide cex4 cca sysfs attributes for cex3 for zcrypt device driver.
 
 - Expose only minimal interface to walk physmem for mm/memblock. This
   is a common code change and it has been agreed on with Mike Rapoport
   and Andrew Morton that this can go upstream via the s390 tree.
 
 - Rework of the s390 vmem/vmmemap code to allow for future memory hot
   remove.
 
 - Get rid of FORCE_MAX_ZONEORDER to finally allow for order-10
   allocations again, instead of only order-8 allocations.
 
 - Various small improvements and fixes.

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.
