Russell Currey 31bbd45af3 powerpc/powernv/pci: Reduce spam when dumping PEST
Dumping the PE State Tables (PEST) can be highly verbose if a number of PEs
are affected, especially in the case where the whole PHB is frozen and 512
lines get printed.  Check for duplicates when dumping the PEST to reduce
useless output.

For example:

    PE[0f8] A/B: 9700002600000000 80000080d00000f8
    PE[0f9] A/B: 8000000000000000 0000000000000000
    PE[..0fe] A/B: as above
    PE[0ff] A/B: 8440002b00000000 0000000000000000

instead of:

    PE[0f8] A/B: 9700002600000000 80000080d00000f8
    PE[0f9] A/B: 8000000000000000 0000000000000000
    PE[0fa] A/B: 8000000000000000 0000000000000000
    PE[0fb] A/B: 8000000000000000 0000000000000000
    PE[0fc] A/B: 8000000000000000 0000000000000000
    PE[0fd] A/B: 8000000000000000 0000000000000000
    PE[0fe] A/B: 8000000000000000 0000000000000000
    PE[0ff] A/B: 8440002b00000000 0000000000000000

and you can imagine how much worse it can get for 512 PEs.

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

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
