Fix a bad interaction between the scv handling and the fallback L1D flush, which could lead to user register corruption. Only affects people using scv (~no one) on machines with old firmware that are missing the L1D flush. Two small selftest fixes. Thanks to Eirik Fuller, Libor Pechacek, Nicholas Piggin, Sandipan Das, Tulio Magno Quites Machado Filho. -----BEGIN PGP SIGNATURE----- iQJHBAABCAAxFiEEJFGtCPCthwEv2Y/bUevqPMjhpYAFAmAMrdETHG1wZUBlbGxl cm1hbi5pZC5hdQAKCRBR6+o8yOGlgF+xD/97Hl6qlS5GllC1mVHUW/eyekfqt7io XHSPeeayZddj3FhfX+eyfICUtmeQP9MXhp9Jyz/JyD+RCpIIiEbJ40CnCpsLeOFj RmRxiVX1lB8tEp5gMZnVdv8z3XDTkzt9YDPlHA7Ta/rqkD0ursF8yVnDG61ZjWnF +2uAozJp9p+nOVrd6wqd5wzdJyWyVXHCkCfyN/HD1rPAR0b6oFm8R3Pca7UR6Qk3 Nt5deAaTisl3jDT+1C+PNq/YErHeERwNyLcRP7dT7VvO9Cch2ijxqc3e0loLT1Nz bTL6bI1JhqePXZQRWRTxpk0A6yss0hWlMudSoRbQzhDbcEY+4QxK90oXevalHXcC C3e3qgO6JoN1hN4tw9kFQr1r+x+xsKpR+jO9MfE7ndFGfAPc2An5rSRbFEB6cUvr qqVh3iNHNGILeE74EyAthjGF2nZEmxI1DAFZFjoDoeWMi+VyE2MAzcIMJg22mhYx 5n64CCrqqTjhXtJgXm31L8WUKHz2JZnwwH3nTnrPXswzTMhkYp2fTQSySWCE4Zyo xygoMfnxIuNkL3hZN0cxNzjr0uGrWIdQq/JFui1Wek68qNK0NEH5r5FmDTTFgk0D A3sJAEmKehs3Ka64LA5ejYza0zU1wnrOcyJKDpxQAWKldcKiQQw7Gup9dQe218Vc ZemyuT9YDlOilQ== =4nYe -----END PGP SIGNATURE----- Merge tag 'powerpc-5.11-5' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux Pull powerpc fixes from Michael Ellerman: - Fix a bad interaction between the scv handling and the fallback L1D flush, which could lead to user register corruption.

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.
