Aneesh Kumar K.V 677733e296 powerpc/book3s64/mm: Don't do tlbie fixup for some hardware revisions 
The store ordering vs tlbie issue mentioned in commit
a5d4b5891c ("powerpc/mm: Fixup tlbie vs store ordering issue on
POWER9") is fixed for Nimbus 2.3 and Cumulus 1.3 revisions. We don't
need to apply the fixup if we are running on them

We can only do this on PowerNV. On pseries guest with KVM we still
don't support redoing the feature fixup after migration. So we should
be enabling all the workarounds needed, because whe can possibly
migrate between DD 2.3 and DD 2.2

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.
