Linus Torvalds 617e7481d7 remoteproc updates for v5.9
This introduces a new "detached" state for remote processors that are
 deemed to be running at the time Linux boots and the infrastructure for
 "attaching" to these. It then introduces the support for performing this
 operation for the STM32 platform.
 
 The coredump functionality is moved out from the core file and gains
 support for an optional mode where the recovery phase awaits the
 notification from devcoredump that the dump should be released. This
 allows userspace to grab the coredump in scenarios where vmalloc space
 is too low for creating a complete copy of the coredump before handing
 this to devcoredump.
 
 A new character device based interface is introduced to allow tying the
 stoppage of a remote processor to the termination of a user space
 process. This is useful in situations when such process provides crucial
 resources/operations for the firmware running on the remote processor.
 
 The Texas Instrument K3 driver gains support for the C66x and C71x DSPs.
 
 Qualcomm remoteprocs gains support for stashing relocation information
 in IMEM, to aid post mortem debugging and the crash notification
 mechanism is generalized to be reusable in cases where loosely coupled
 drivers needs to know about the status of a remote processor. One such
 example is the IPA hardware block, which is jointly owned with the
 modem and migrated to this improved interface.
 
 It also introduces a number of bug fixes and debug improvements for the
 Qualcomm modem remoteproc driver.
 
 And it cleans up the inconsistent interface for remoteproc drivers to
 implement power management.

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.
