Mahesh Salgaonkar d6e8a15085 powerpc/powernv/mce: Reduce MCE console logs to lesser lines.
Also add cpu number while displaying MCE log. This will help cleaner
logs when MCE hits on multiple cpus simultaneously.

Before the changes the MCE output was:

  Severe Machine check interrupt [Recovered]
    NIP [d00000000ba80280]: insert_slb_entry.constprop.0+0x278/0x2c0 [mcetest_slb]
    Initiator: CPU
    Error type: SLB [Multihit]
      Effective address: d00000000ba80280

After this patch series changes the MCE output will be:

  MCE: CPU80: machine check (Warning) Host SLB Multihit [Recovered]
  MCE: CPU80: NIP: [d00000000b550280] insert_slb_entry.constprop.0+0x278/0x2c0 [mcetest_slb]
  MCE: CPU80: Probable software error (some chance of hardware cause)

UE in host application:

  MCE: CPU48: machine check (Severe) Host UE Load/Store DAR: 00007fffc6079a80 paddr: 0000000f8e260000 [Not recovered]
  MCE: CPU48: PID: 4584 Comm: find NIP: [0000000010023368]
  MCE: CPU48: Hardware error

and for MCE in Guest:

  MCE: CPU80: machine check (Warning) Guest SLB Multihit DAR: 000001001b6e0320 [Recovered]
  MCE: CPU80: PID: 24765 Comm: qemu-system-ppc Guest NIP: [00007fffa309dc60]
  MCE: CPU80: Probable software error (some chance of hardware cause)

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.
