      [libata] struct pci_dev related cleanups · 2855568b
      由 Jeff Garzik 提交于 
      * remove pointless pci_dev_to_dev() wrapper.  Just directly reference
  the embedded struct device like everyone else does.

* pata_cs5520: delete cs5520_remove_one(), it was a duplicate of
  ata_pci_remove_one()

* linux/libata.h: don't bother including linux/pci.h, we don't need it.
  Simply declare 'struct pci_dev' and assume interested parties will
  include the header, as they should be doing anyway.

* linux/libata.h: consolidate all CONFIG_PCI declarations into a
  single location in the header.

      libata: use ata_exec_internal() for PMP register access · b06ce3e5
      由 Tejun Heo 提交于 
      PMP registers used to be accessed with dedicated accessors ->pmp_read
and ->pmp_write.  During reset, those callbacks are called with the
port frozen so they should be able to run without depending on
interrupt delivery.  To achieve this, they were implemented polling.

However, as resetting the host port makes the PMP to isolate fan-out
ports until SError.X is cleared, resetting fan-out ports while port is
frozen doesn't buy much additional safety.

This patch updates libata PMP support such that PMP registers are
accessed using regular ata_exec_internal() mechanism and kills
->pmp_read/write() callbacks.  The following changes are made.

* PMP access helpers - sata_pmp_read_init_tf(), sata_pmp_read_val(),
  sata_pmp_write_init_tf() are folded into sata_pmp_read/write() which
  are now standalone PMP register access functions.

* sata_pmp_read/write() returns err_mask instead of rc.  This is
  consistent with other functions which issue internal commands and
  allows more detailed error reporting.

* ahci interrupt handler is modified to ignore BAD_PMP and
  spurious/illegal completion IRQs while reset is in progress.  These
  conditions are expected during reset.

      libata: implement ATA_PFLAG_RESETTING · afaa5c37
      由 Tejun Heo 提交于 
      Implement ATA_PFLAG_RESETTING.  This flag is set while reset is in
progress.  It's set before prereset is called and cleared after reset
fails or postreset is finished.

This flag itself doesn't have any function.  It will be used by LLDs
to tell whether reset is in progress if it needs to behave differently
during reset.

      ahci: fix notification handling · 5f226c6b
      由 Tejun Heo 提交于 
      Asynchronous notification on ICH9 didn't work because it didn't write
AN FIS into the RX area - it only updates SNotification.  Also,
snooping SDB_FIS RX area is racy against further SDB FIS receptions.
Let sata_async_notification() determine using SNTF if it's available
and snoop RX area iff SNTF isn't available

      ahci: kill leftover from enabling NCQ over PMP · 75da6d2b
      由 Tejun Heo 提交于 
      ahci had problems with NCQ over PMP and NCQ used to be disabled while
PMP was attached.  After fixing the problem, the temporary NCQ
disabling code wasn't removed completely.  Kill the remaining piece.

      Tasks in uninterruptible sleep might be woken up by unrelated events
and should check whether the condition it was waiting for has actually
triggered.  Wrap schedule_timeout_uninterruptible() in loop to achieve
it.

      libata: skip suppress reporting if ATA_EHI_QUIET · 94ff3d54
      由 Tejun Heo 提交于 
      ATA_EHI_NO_AUTOPSY and ATA_EHI_QUIET are used during initial probing
to skip exception analysis and reporting.  Usually, there's nothing to
report but on some allowed but rare corner cases (e.g. phy status
changed interrupt when IRQ is enabled on frozen port - this happens if
IRQ pending status isn't cleared in the IRQ router or controller)
exception messages get printed.

Skip reporting if ATA_EHI_QUIET is set.
