ce44e19701 ACPI: ACPI thermal zone handle notification correctly
Change the ACPI thermal action upon notification 0x81 and 0x82.

According to the ACPI spec, we should:
re-evaluate _PSV and _ACx methods upon notification 0x81
re-evaluate _PSL and _ALx and _TZD upon notificaiton 0x82.
But the current code re-evaluates all the trip points for 0x81 while
only re-evaluates _TZD for 0x82.

Fix this violation of ACPI spec.

TODO: devices in _PSL, _ALx and _TZD may change after a notification 0x82.
      At this time, we need to re-bind the cooling devices with the thermal zone.

3f655ef8c4 ACPI: register ACPI thermal zone as generic thermal zone devices
Register ACPI thermal zone as thermal zone device.

the new sys I/F for ACPI thermal zone will be like this:

/sys/class/thermal:
|thermal_zone1:
	|-----type:			"ACPI thermal zone". RO
	|-----temp:			the current temperature. RO
	|-----mode:			the current working mode. RW.
					the default value is "kernel"  which means  thermal
					management is done by ACPI thermal driver.
					"echo user > mode" prevents all the ACPI thermal driver
					actions upon any trip points.
	|-----trip_point_0_temp:	the threshold of trip point 0. RO.
	|-----trip_point_0_type:	"critical". RO.
					the type of trip point 0
					This may be one of critical/hot/passive/active[x]
					for an ACPI thermal zone.
	...
	|-----trip_point_3_temp:
	|-----trip_point_3_type:	"active[1]"

a14dc57495 ide: move hwif_register() call out of ide_probe_port()
* Add BUG_ON(hwif->present) at the start of ide_probe_port().

* Move hwif_register() call (along with setting hwif->present) from
  ide_probe_port() to ide_device_add_all().

  As a result the port will be registered with the device tree _after_:
  - probing both devices (if both are present)
  - port reset (if hwif->reset is set)
  - restoring local IRQs state and re-enabling port IRQ

While at it:

* Rename hwif_register() to ide_register_port().

* Move amd_config->base from AMD_* defines to users of these defines and add
  0x40 the defined values.  Then add amd_offset() inline helper for selecting

  the hdparm friendly format (== the identify data can be extracted from
  dmesg output and passed to hdparm --Istdin).

* Dump identify data in ide-probe.c::do_identify() if DEBUG is enabled.
