One non-fix, the conversion of vio_driver->remove() to return void, which touches various powerpc specific drivers. Fix the privilege checks we do in our perf handling, which could cause soft/hard lockups in some configurations. Fix a bug with IRQ affinity seen on kdump kernels when CPU 0 is offline in the second kernel. Fix missed page faults after mprotect(..., PROT_NONE) on 603 (32-bit). Fix a bug in our VSX (vector) instruction emulation, which should only be seen when doing VSX ops to cache inhibited mappings. Three commits fixing various build issues with obscure configurations.

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.
