Add missing newline to dev_warn() message string. This is more of an issue
with older kernels that don't automatically add a newline if it was missing
from the end of the previous line.

The max junction temperature of Atom N450/D410/D510 CPUs is 100 degrees
Celsius. Since these CPUs are always coupled with Intel NM10 chipset in
one package, the best way to verify whether an Atom CPU is N450/D410/D510
is to check the host bridge device.

Following patch adds support for mobile Penryn CPUs. Intel documents this
poorly. I asked the Coretemp author for some help. This is totally untested and
may not work. Please test!

Fix Atom CPUs support. Intel documents TjMax at 90 degrees C but
some Atoms may have 125 degrees C (this is undocumented speculation).

Enable the coretemp driver on an Intel Atom.
I'm not sure if the readings are correct, however - on my 330, the driver
reports values between 27 and 41 °C (with core1 being about 8°C hotter
than core0, given the same load). Maybe the maximum temperature of 100 °C
is wrong for Atom CPUs.

This patch adds support for family 0x17, which has Penryn Core. It should also

Following patch will finally solve the detection of Intel Mobile CPUs which
share same CPUID with Desktop/Server CPUs. We need this information to test
some bit so we know if TjMax is 100C or 85C. Intel claims this works for mobiles
only, respect that and set for desktops the TjMax to 100C. Intel provided some
table on their wiki based on my chat with them at:

Fix following warning:
WARNING: vmlinux.o(.text+0xebfd04): Section mismatch in reference from the function coretemp_cpu_callback() to the function .cpuinit.text:coretemp_device_add()
coretemp_cpu_callback() are only used inside a
HOTPLUG_CPU block so annotate it __cpuinit.
The notifier referencing the function are annotated
__refdata to silence warning from the exit function.
The unregister function do not use the embedded pointer
but clears the variable so the annotation is OK.

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
in action.
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.

cpu_data is currently an array defined using NR_CPUS. This means that
we overallocate since we will rarely really use maximum configured cpus.
When NR_CPU count is raised to 4096 the size of cpu_data becomes
3,145,728 bytes.
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().
cpu_data is defined to be the boot_cpu_data structure for the NON-SMP
case.

The CPU hotplug notifier_block coretemp_cpu_notifier is already defined
inside an #ifdef HOTPLUG_CPU, therefore marking it as __cpuinitdata is
quite a pointless thing to do.
Also, remove duplicate prototype of function coretemp_update_device()
at the top of this file (another one already exists barely 10 lines
above this one :-)

Since nonboot CPUs are now disabled after tasks and devices have been
frozen and the CPU hotplug infrastructure is used for this purpose, we need
special CPU hotplug notifications that will help the CPU-hotplug-aware
subsystems distinguish normal CPU hotplug events from CPU hotplug events
related to a system-wide suspend or resume operation in progress. This
patch introduces such notifications and causes them to be used during
suspend and resume transitions. It also changes all of the
CPU-hotplug-aware subsystems to take these notifications into consideration
(for now they are handled in the same way as the corresponding "normal"
ones).
