1c51361a98 ide: add IDE_HFLAG_SERIALIZE host flag
Add IDE_HFLAG_SERIALIZE host flag to tell ide_pci_setup_ports() to set
hwif/mate->serialized and convert aec62xx, cs5530 and sc1200 host drivers
to use it.

40d2dd7ef3 piix: add DECLARE_ICH_DEV() macro
Add DECLARE_ICH_DEV() macro.

While at it:

* Add init_hwif_ich() (->init_hwif method) for ICH controllers.

* Rename init_chipset_piix() to init_chipset_ich() and use it only for
  ICH controllers.

* Remove no longer needed piix_is_ichx() helper.

  now always tune PIO it will be disabled by ->set_pio_mode calls anyway).

* Bump driver version.

* Pass ide_pci_device_t *d to setup-pci.c::ide_get_or_set_dma_base()
  and use d->name instead of hwif->cds->name.

* Set IDE_HFLAG_CS5520 host flag in cs5520 host driver and use it in
  ide_get_or_set_dma_base() to find out which PCI BAR to use, remove no longer
  needed cs5520.c::cs5520_init_setup_dma() and ide_pci_device_t.init_setup_dma.

  This fixes PCI bus-mastering not being checked for CS5510/CS5520 hosts.

612b5a8d3a IPMI: new NMI handling
Convert over to the new NMI handling for getting IPMI watchdog timeouts via an
NMI.  This add config options to know if there is the ability to receive NMIs
and if it has an NMI post processing call.  Then it modifies the IPMI watchdog
to take advantage of this so that it can know if an NMI comes in.

It also adds testing that the IPMI NMI watchdog works.

fcfa472411 IPMI: add polled interface
Currently the IPMI watchdog timer sets the watchdog timeout on a panic, but it
doesn't actually poll the interface to make sure the message goes out.

Add an interface for polling the IPMI driver, and add code to the IPMI
watchdog timer to poll the interface when the timer is set from a panic.

650dd0c7fa IPMI: documentation fixes
Clean up IPMI documentation to remove references to high-res timers and add
info about the polling thread.  Also fix an doc error for a parameter.

f8fbcd3b9d IPMI: remove bogus semaphore from watchdog
Lockdep was giving an error when loading the IPMI watchdog module.  It turns
out that if you try to claim a lock in a parameter handling routine, lockdep
won't see that lock as "static" yet because the module is not yet on the
module list, so it will complain.

However, the semaphore in question is completely unnecessary.  So just remove
it.

c45adc3915 IPMI: don't init irq until ready
Patrick found a race at startup.  Interrupts were being enabled for the IPMI
interface before the driver was really ready to handle them.  This could
result in an oops if something was pending on the interface at startup and
interrupt were already enabled (technically shouldn't happen, but need to
cover for this in real life).  So move the IRQ setup to the code that starts
the actual IPMI processing.
