With commit c814a4c7c4, the meaning of tempX_max
was changed. It no longer returns the value of bits 8:15 of
MSR_IA32_TEMPERATURE_TARGET, but instead returns the value of CPU threshold
register T1. tempX_max_hyst was added to reflect the value of temperature
threshold register T0.
As it turns out, T0 and T1 are used on some systems, presumably by the BIOS.
Also, T0 and T1 don't have a well defined meaning. The thresholds may be used
as upper or lower limits, and it is not guaranteed that T0 <= T1. Thus, the new
attribute mapping does not reflect the actual usage of the threshold registers.
Also, register contents are changed during runtime by an entity other than the
hwmon driver, meaning the values cached by the driver do not reflect actual
register contents.
Revert most of c814a4c7c4 to address the problem.
Support for T0 and T1 will be added back in with a separate commit, using new
attribute names.

On old CPUs (and even some recent Atom CPUs) TjMax can't be read from
the CPU registers, so it is guessed by the driver using a complex
heuristic which isn't reliable. So let users who know their CPU's
TjMax pass it as a module parameter.

Function get_pkg_tjmax is a simplified copy of get_tjmax. Drop it and
always use get_tjmax, result is the same and this avoids code
duplication.
Also make get_tjmax less verbose: don't warn about MSR read failure
when failure was expected, and don't report TjMax in the logs unless
debugging is enabled.

This patch adds the core and pkg support to coretemp.
These thresholds can be configured via the sysfs interfaces tempX_max
and tempX_max_hyst. An interrupt is generated when CPU temperature reaches
or crosses above tempX_max OR drops below tempX_max_hyst.

CPUs are known to have TiMax other than 100 degrees C, and even though the code
in adjust_tjmax() explicitly handles those CPUs and points to a Web document
listing several of the affected CPU IDs.
Reinstate original TjMax adjustment if TjMax can not be determined using the

The coretemp driver provides a single set of device attributes for each
physical core of a HT CPU to avoid duplicate sensors. This
functionality was introduced with commit d883b9f097 ("hwmon:
(coretemp) Skip duplicate CPU entries").
Commit e40cc4bdfd ("x86/hwmon: register alternate sibling upon CPU
removal") extends this functionality to register the HT sibling of a CPU
which is taken offline, to ensure that sensor attributes are provided if
at least one HT sibling of a core is online.

This fix is only a workaround. For a real fix, cpu_sibling_mask() should
be defined in UP include code, eg in linux/smp.h, and asm/smp.h should not be
included directly. This fix is currently not possible because asm/smp.h defines

Just like pkgtemp registers another core of the same package when one
gets removed, coretemp should register another hyperthread (if
available) in that situation.
As pointed out in the patch fixing the respective code in pkgtemp, the
list protectng mutex must be dropped before calling
coretemp_device_add(), and due to the restructured loop (including an
explicit return) the "safe" variant of the list iterator isn't needed

It's not permitted to unregister a device after devices have been suspended.
It causes deadlocks to appear on systems with coretemp hwmon loaded. To avoid
this, we can make coretemp_cpu_callback() do nothing if the _FROZEN bit is set

Also, in other cases it's generally too late to unregister the coretemp device
if the CPU is already dead, so it should be unregistered on CPU_DOWN_PREPARE.

These changes were adopted from the sparc64 (and ia64) code. An
additional field was added to cpuinfo_x86 to be a non-ambiguous cpu
index. This corresponds to the index into a cpumask_t as well as the
per_cpu index. It's used in various places like show_cpuinfo().
