Pull PCI fixes from Bjorn Helgaas:

 - Remove ASPM L0s support for MSM8996 SoC since we now enable L0s when
   advertised, and it caused random hangs on this device (Manivannan
   Sadhasivam)

 - Fix meson-pcie to report that the link is up while in ASPM L0s or L1,
   since those are active states from the software point of view, and
   treating the link as down caused config access failures (Bjorn
   Helgaas)

 - Fix up sparc DTS BAR descriptions that are above 4GB but not marked
   as prefetchable, which caused resource assignment and driver probe
   failures after we converted from the SPARC pcibios_enable_device() to
   the generic version (Ilpo Järvinen)

Linux kernel
============

The Linux kernel is the core of any Linux operating system. It manages hardware,
system resources, and provides the fundamental services for all other software.

Quick Start
-----------

* Report a bug: See Documentation/admin-guide/reporting-issues.rst
* Get the latest kernel: https://kernel.org
* Build the kernel: See Documentation/admin-guide/quickly-build-trimmed-linux.rst
* Join the community: https://lore.kernel.org/

Essential Documentation
-----------------------

All users should be familiar with:

* Building requirements: Documentation/process/changes.rst
* Code of Conduct: Documentation/process/code-of-conduct.rst
* License: See COPYING

Documentation can be built with make htmldocs or viewed online at:
https://www.kernel.org/doc/html/latest/
