Old GCCs (4.6.3 at least), aren't able to follow the logic in
__kvmhv_copy_tofrom_guest_radix() and warn that old_pid is used
uninitialized:
arch/powerpc/kvm/book3s_64_mmu_radix.c:75:3: error: 'old_pid' may be
used uninitialized in this function
The logic is OK, we only use old_pid if quadrant == 1, and in that
case it has definitely be initialised, eg:
if (quadrant == 1) {
old_pid = mfspr(SPRN_PID);
...
if (quadrant == 1 && pid != old_pid)
mtspr(SPRN_PID, old_pid);
Annotate it to fix the error.

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.
