Heiner Kallweit says: ==================== PCI: Add and use constant PCI_STATUS_ERROR_BITS and helper pci_status_get_and_clear_errors Several drivers have own definitions for this constant, so move it to the PCI core. In addition in multiple places the following code sequence is used: 1. Read PCI_STATUS 2. Mask out non-error bits 3. Action based on set error bits 4. Write back set error bits to clear them As this is a repeated pattern, add a helper to the PCI core. Most affected drivers are network drivers. But as it's about core PCI functionality, I suppose the series should go through the PCI tree. v2: - fix formal issue with cover letter v3: - fix dumb typo in patch 7 v4: - add patches 1-3 - move new constant PCI_STATUS_ERROR_BITS to include/linux/pci.h - small improvements in commit messages ==================== Signed-off-by: David S.

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.
