Current Temperature for K8 RevG desktop CPUs is a "normalized value"
which can be below ambient temperature.
As a consequence lots of RevG systems report temperatures like:
$ sensors
k8temp-pci-00c3
Adapter: PCI adapter
Core0 Temp: +17 C
Core0 Temp: +3 C
Core1 Temp: +21 C
Core1 Temp: +5 C
being quite below ambient temperature.
There are even reports of negative temperature values.
This patch corrects the temperature reporting of k8temp for
RevG desktop CPUs.

Meaning of ThermSenseCoreSel bit was inverted beginning with K8 RevF.
That means with current driver temp1/temp2 belong to core 1 and
temp3/temp4 belong to core 0 on a K8 RevF/RevG CPU.
This patch ensures that temp1/temp2 always belong to core 0 and
temp3/temp4 to core 1 for all K8 revisions.

Add warning about wrong CPU temperature readouts on all fam F rev F.
The allowed combinations of processors ensure that all processors
in a multisocket system have similar characteristics, e.g.
(1) provide temperature sensor interface (>=RevC && <RevF)
(2) are affected by erratum #141 (>=RevF)
Thus it is sufficient to check the revision of the boot CPU.
For "mixed silicon support" refer to
"Revision Guide for AMD Athlon 64 and AMD Opteron Processors" (RevA-E) and
"Revision Guide for AMD NPT Family 0Fh Processors" (RefF-G).

Restart the request queue early for REQ_TYPE_PM_RESUME requests
(though there is only one resume request for the whole resume
sequence it stays in the queue until is fully completed and now
depends on kblockd for processing consequential resume states).

This patch is used to help Jean Delvare to get rid of drivers/i2c/chips/

83xx specific it's placed into arch/powerpc/platforms/83xx/.

Commit b430428a18 ("8250: Don't clobber
spinlocks.") introduced a regression on the parisc architecture, which
broke the handover to the serial port at boottime.
early_serial_setup() was changed to only copy a subset of the uart_port
fields, and sadly the "type" and "line" fields were forgotten and thus
the serial port was not initialized and could not be used for a
handover. This patch fixes this by copying the missing fields.
As this change to early_serial_setup() doesn't need an initialized
spinlock in the uart_port struct any longer, we can drop the spinlock
initialization in the superio driver.

Always pass a struct device if one is available; and there's really
no reason for the processor specific stuff in this file if only
