turbostat recently gained a feature adding APIC and X2APIC columns.
While they are disabled by-default, they are enabled with --debug
or when explicitly requested, eg.
$ sudo turbostat --quiet --show Package,Node,Core,CPU,APIC,X2APIC date
But these columns erroneously showed zeros on AMD hardware.

cpupower crashes on VMWare guests. The guests have the AMD PStateDef MSR
(0xC0010064 + state number) set to zero. As a result fid and did are zero
and the crash occurs because of a divide by zero (cof = fid/did). This
can be prevented by checking the enable bit in the PStateDef MSR before
calculating cof. By doing this the value of pstate[i] remains zero and
the value can be tested before displaying the active Pstates.
Check the enable bit in the PstateDef register for all supported families
and only print out enabled Pstates.

The strncpy doesn't null terminate the string because the size is too
short by one byte.

The normal method of passing the length of the destination buffer works

Almost all files in the kernel are either plain text or UTF-8 encoded. A
couple however are ISO_8859-1, usually just a few characters in a C
comments, for historic reasons.
This converts them all to UTF-8 for consistency.

Pull turbostat utility fixes for 4.18 from Len Brown:
"Three of them are for regressions since Linux-4.17"
* 'turbostat' of git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux:
tools/power turbostat: version 18.07.27
tools/power turbostat: Read extended processor family from CPUID
tools/power turbostat: Fix logical node enumeration to allow for non-sequential physical nodes
tools/power turbostat: fix x2apic debug message output file
tools/power turbostat: fix bogus summary values
tools/power turbostat: fix -S on UP systems
tools/power turbostat: Update turbostat(8) RAPL throttling column description
This fixes the reported family on modern AMD processors (e.g. Ryzen,
which is family 0x17). Previously these processors all showed up as
family 0xf.
See the document
https://support.amd.com/TechDocs/56255_OSRR.pdf
section CPUID_Fn00000001_EAX for how to calculate the family
from the BaseFamily and ExtFamily values.

turbostat fails on some multi-package topologies because the logical node
enumeration assumes that the nodes are sequentially numbered,
which causes the logical numa nodes to not be enumerated, or enumerated incorrectly.
Use a more robust enumeration algorithm which allows for non-seqential physical nodes.

This patch fixes a regression introduced in
commit 8cb48b32a5 ("tools/power turbostat: track thread ID in cpu_topology")
Turbostat uses incorrect cores number ('topo.num_cores') - its value is count
of logical CPUs, instead of count of physical cores. So it is twice as large as
it should be on a typical Intel system. For example, on a 6 core Xeon system
'topo.num_cores' is 12, and on a 52 core Xeon system 'topo.num_cores' is 104.
And interestingly, on a 68-core Knights Landing Intel system 'topo.num_cores'
is 272, because this system has 4 logical CPUs per core.
As a result, some of the turbostat calculations are incorrect. For example,
on idle 52-core Xeon system when all cores are ~99% in Core C6 (CPU%c6), the
summary (very first) line shows ~48% Core C6, while it should be ~99%.
This patch fixes the problem by fixing 'topo.num_cores' calculation.
Was:
1. Init 'thread_id' for all CPUs to -1
2. Run 'get_thread_siblings()' which sets it to 0 or 1
3. Increment 'topo.num_cores' when thread_id != -1 (bug!)
Now:
1. Init 'thread_id' for all CPUs to -1
2. Run 'get_thread_siblings()' which sets it to 0 or 1
3. Increment 'topo.num_cores' when thread_id is not 0
I did not have a chance to test this on an AMD machine, and only tested on a
couple of Intel Xeons (6 and 52 cores).

Running turbostat on machines that don't expose nodes
in sysfs (no /sys/bus/node) causes a segfault or a -nan
value diesplayed in the log. This is caused by
physical_node_id being reported as -1 and logical_node_id
being calculated as a negative number resulting in the new
GET_THREAD/GET_CORE returning an incorrect address.
