Linus Torvalds e98e03d075 s390 updates for the 5.14 merge window #2
- Fix preempt_count initialization.
 
 - Rework call_on_stack() macro to add proper type handling and avoid
   possible register corruption.
 
 - More error prone "register asm" removal and fixes.
 
 - Fix syscall restarting when multiple signals are coming in. This adds
   minimalistic trampolines to vdso so we can return from signal without
   using the stack which requires pgm check handler hacks when NX is
   enabled.
 
 - Remove HAVE_IRQ_EXIT_ON_IRQ_STACK since this is no longer true after
   switch to generic entry.
 
 - Fix protected virtualization secure storage access exception handling.
 
 - Make machine check C handler always enter with DAT enabled and move
   register validation to C code.
 
 - Fix tinyconfig boot problem by avoiding MONITOR CALL without CONFIG_BUG.
 
 - Increase asm symbols alignment to 16 to make it consistent with
   compilers.
 
 - Enable concurrent access to the CPU Measurement Counter Facility.
 
 - Add support for dynamic AP bus size limit and rework ap_dqap to deal
   with messages greater than recv buffer.

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.
