Some processors use the Interrupt Response Time Limit (IRTL) MSR value
to describe the maximum IRQ response time latency for deep
package C-states. (Though others have the register, but do not use it)
Lets print it out to give insight into the cases where it is used.
IRTL begain in SNB, with PC3/PC6/PC7, and HSW added PC8/PC9/PC10.

turbostat already checks whether calling each cpuid leavf is legal,
and it doesn't look at the function return value,
so call the simpler gcc intrinsic __cpuid() instead of __get_cpuid().

The accuracy of Bzy_Mhz and Busy% depend on reading
the TSC, APERF, and MPERF close together in time.
When there is a very short measurement interval,
or a large system is profoundly idle, the changes
in APERF and MPERF may be very small.
They can be small enough that an expensive interrupt
between reading APERF and MPERF can cause the APERF/MPERF
ratio to become inaccurate, resulting in invalid
calculation and display of Bzy_MHz.
A dummy APERF read of APERF makes this problem
much more rare. Apparently this 1st systemn call
after exiting a long stretch of idle is when we
typically see expensive timer interrupts that cause
large jitter.
For the cases that dummy APERF read fails to prevent,
we compare the latency of the APERF and MPERF reads.
If they differ by more than 2x, we re-issue them.

The column "GFX%c6" show the percentage of time the GPU
is in the "render C6" state, rc6. Deep package C-states on several
systems depend on the GPU being in RC6.
This information comes from the counter
/sys/class/drm/card0/power/rc6_residency_ms,
as read before and after the measurement interval.

Under the column "GFXMHz", show a snapshot of this attribute:
/sys/class/graphics/fb0/device/drm/card0/gt_cur_freq_mhz
This is an instantaneous snapshot of what sysfs presents
at the end of the measurement interval. turbostat does
not average or otherwise perform any math on this value.

The new IRQ column shows how many interrupts have occurred on each CPU
during the measurement inteval. This information comes from
the difference between /proc/interrupts shapshots made before
and after the measurement interval.
The first row, the system summary, shows the sum of the IRQS
for all CPUs during that interval.

Following changes have been made:
- changed MSR_NHM_TURBO_RATIO_LIMIT to MSR_TURBO_RATIO_LIMIT in debug print
for consistency with Developer Manual
- updated definition of bitfields in MSR_TURBO_RATIO_LIMIT and appropriate
parsing code
- added x200 to list of architectures that do not support Nahlem compatible
definition of MSR_TURBO_RATIO_LIMIT register (x200 has the register but
bits definition is custom)
- fixed typo in code that parses MSR_TURBO_RATIO_LIMIT
(logical instead of bitwise operator)
- changed MSR_TURBO_RATIO_LIMIT parsing algorithm so the print out had the
same order as implementations for other platforms

x200 does not enable any way to programmatically obtain bus clock
speed. Bclk for the architecture has a fixed value of 100 MHz.
At the same time x200 cannot be included in has_snb_msrs since
it does not support C7 idle state.
prior to this patch, MHz values reported on this chip
were erroneously calculated using bclk of 133MHz,
causing MHz values to be reported 33% higher than actual.

two of them last week, but they were accidentally skipped :-(.
- One fix to an error path in the core
- One fix for RoCE in the core
- Two related fixes for the core/mlx5"

Pull drm fixes from Dave Airlie:
"This contains one i915 patch twice, as I merged it locally for
testing, and then pulled some stuff in on top, and then Jani sent to
me, I didn't think it was worth redoing all the merges of what I had
tested.
Summary:
- amdgpu/radeon fixes for some more power management and VM races.
- Two i915 fixes, one for the a recent regression, one another power
management fix for skylake.
- Two tegra dma mask fixes for a regression.
- One ast fix for a typo I made transcribing the userspace driver,
that I'd like to get into stable so I don't forget about it"

Pull power management and ACPI fixes from Rafael Wysocki:
"Two build fixes for cpufreq drivers (including one for breakage
introduced recently) and a fix for a graph tracer crash when used over
suspend-to-RAM on x86.
Specifics:
- Prevent the graph tracer from crashing when used over suspend-to-
RAM on x86 by pausing it before invoking do_suspend_lowlevel() and
un-pausing it when that function has returned (Todd Brandt).
- Fix build issues in the qoriq and mediatek cpufreq drivers related
to broken dependencies on THERMAL (Arnd Bergmann)"

Pull arm64 fix from Will Deacon:
"Arm64 fix for -rc7. Without it, our struct page array can overflow
the vmemmap region on systems with a large PHYS_OFFSET.
Nothing else on the radar at the moment, so hopefully that's it for
4.5 from us.
Summary: Ensure struct page array fits within vmemmap area"

Pull jffs2 fixes from David Woodhouse:
"This contains two important JFFS2 fixes marked for stable:
- a lock ordering problem between the page lock and the internal
f->sem mutex, which was causing occasional deadlocks in garbage
collection
- a scan failure causing moved directories to sometimes end up
appearing to have hard links.
There are also a couple of trivial MAINTAINERS file updates"

git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
Pull tracing fix from Steven Rostedt:
"A feature was added in 4.3 that allowed users to filter trace points
on a tasks "comm" field. But this prevented filtering on a comm field
that is within a trace event (like sched_migrate_task).
When trying to filter on when a program migrated, this change
prevented the filtering of the sched_migrate_task.
To fix this, the event fields are examined first, and then the extra
fields like "comm" and "cpu" are examined. Also, instead of testing
to assign the comm filter function based on the field's name, the
generic comm field is given a new filter type (FILTER_COMM). When
this field is used to filter the type is checked. The same is done
for the cpu filter field.
Two new special filter types are added: "COMM" and "CPU". This allows
users to still filter the tasks comm for events that have "comm" as
one of their fields, in cases that users would like to filter
sched_migrate_task on the comm of the task that called the event, and
not the comm of the task that is being migrated"
