Ian Romanick 59ca535576 util: Use maximum number of CPUs for determining cache topology
This prevents problems when some CPUs are offline.  In a four CPU
system, if CPUs 1 and 2 are offline, the cache topology code would
only examine CPUs 0 and 1... giving incorrect information.

The types are changed to int16_t so that the offset of num_L3_caches
does not change.  This triggered a STATIC_ASSERT failure:

STATIC_ASSERT(offsetof(struct util_cpu_caps_t, num_L3_caches) == 5 * sizeof(uint32_t));

I'm assuming there's some assembly code or something that depends on
this offset, and I don't feel like messing with it.

Build & install
---------------

You can find more information in our documentation (`docs/install.rst
<https://mesa3d.org/install.html>`_), but the recommended way is to use
Meson (`docs/meson.rst <https://mesa3d.org/meson.html>`_):

.. code-block:: sh

  $ mkdir build
  $ cd build
  $ meson ..
  $ sudo ninja install

appropriate, you should ask your question on `OFTC's #dri-devel
<irc://irc.oftc.net/dri-devel>`_, someone will redirect you if
necessary.
Remember that not everyone is in the same timezone as you, so it might
take a while before someone qualified sees your question.
