ecf2a80a97 ACPI: thinkpad-acpi: add a fan-control feature master toggle
Len Brown considers that an active by default fan control interface in
laptops may be too close to giving users enough rope.  There is a good
chance he is quite correct on this, especially if someone decides to use
that interface in applets and users are not aware of its risks.

This patch adds a master switch to thinkpad-acpi that enables or disables
the entire fan-control feature as a module parameter: "fan_control".  It
defaults to disabled.  Set it to non-zero to enable fan control.

Also, the patch removes the expermiental status from fan control, since it
is stable enough to not be called experimental, and the master switch makes
it safe enough to do so.

79fff27002 ACPICA: clear fields reserved before FADT r3
Linux-2.6.21 stopped booting on a P4/HT because Linux
wrote the FADT.CST_CNT value to the SMI_CMD.
Apparently this stumbled over some SMM instability,
such as confusing SMM when invoking it from cpu1.

Linux did this because even though the r2 FADT reserves
the CST_CNT field, this BIOS set that field and Linux
used it.

Turns out that up through 2.6.20 we explicitly cleared
cst_control for r2 FADTs.  So here we go back to doing that,
plus also clear some additional fields that are reserved
until FADT r3.

169439c2e3 libata: Handle drives that require a spin-up command before first access
(S)ATA drives can be configured for "power-up in standby",
a mode whereby a specific "spin up now!" command is required
before the first media access.

Currently, a drive with this feature enabled can not be used at all
with libata, and once in this mode, the drive becomes a doorstop.

The older drivers/ide subsystem at least enumerates the drive,
so that it can be woken up after the fact from a userspace HDIO_*
command, but not libata.

This patch adds support to libata for the "power-up in standby"
mode where a "spin up now!" command (SET_FEATURES) is needed.
With this, libata will recognize such drives, spin them up,
and then re-IDENTIFY them if necessary to get a full/complete
set of drive features data.

Drives in this state are determined by looking for
special values in id[2], as documented in the current ATA specs.

Now that host and ap are available during intialization, functions are

paths.  This simplifies code quite a bit.

  ahci_init_one() for init order consistency

eca25dca17 libata: convert drivers with combined SATA/PATA ports to new init model
Convert sata_via and sata_promise to new init model.  Both controllers
can have combined configuration (SATA + PATA) and used twisted
initialization method (modifying port in ->port_start) to overcome
probe_ent limitations.

This patch converts both drivers to new init model in which such
configuration is natively supported.

* promise: Combined pata port now uses separate port_info entry right
  after the sata counterpart entry.

* promise: Controller configuration is discerned using ap->flags.
  This simplifies init path and makes it look more like other LLDs.

* via: Both SATA and PATA ports in vt6421 are represented in their
  own port_info structure.

Tested on PDC20375 (SATA150 TX2plus) [105a:3375] and PDC40775 (SATA

These will be used to convert LLDs to new init model.

* Add irq_handler field to port_info.  In new init model, requesting
  IRQ is LLD's responsibility and libata doesn't need to know about
  irq_handler.  Most LLDs can simply register their irq_handler but
  some need different irq_handler depending on specific chip.  The
  added port_info->irq_handler field can be used by LLDs to select
  the matching IRQ handler in such cases.

* Add ata_dummy_port_info.

  acquire all resources and init the host in one go.

Convert legacy PCI host handling to alloc-init-register model.
ata_init_legacy_host(), ata_request_legacy_irqs() and
ata_pci_init_bmdma() are separated out and follow the new init model.

The two legacy handling functions use separate ata_legacy_devres
instead of generic devm_* resources.  This reduces devres overhead for
legacy hosts which was a bit high because it didn't use PCI/iomap
merged resoruces.

ata_pci_init_one() is rewritten in terms of the aboved functions but
native mode handling is still using the old method.  Conversion will
be completed when native mode handling is updated.

* ata_host_alloc() : allocates host and its ports.  shost is not
  registered automatically.

* ata_scsi_add_hosts() : allocates and adds shosts associated with an
  ATA host.  Used by ata_host_register().

* ata_host_register() : takes a fully initialized ata_host structure
  and registers it to libata layer and probes it.

Only ata_host_alloc() and ata_host_register() are exported.
ata_device_add() is rewritten using the above functions.  This patch
does not introduce any observable behavior change.  Things worth
mentioning.

* print_id is assigned at registration time and LLDs are allowed to
  overallocate ports and reduce host->n_ports during initialization.
  ata_host_register() will throw away unused ports automatically.

* All SCSI host initialization stuff now resides in
  ata_scsi_add_hosts() in libata-scsi.c, where it should be.

* ipr is now the only user of ata_host_init().  Either kill it by
  converting ipr to use ata_host_alloc() and friends or rename and
  move it to libata-scsi.c

ecef725323 libata: separate out ata_host_start()
Separate out ata_host_start() from ata_device_add().  ata_host_start()
calls ->port_start on each port if available and freezes the port.
