8fdcf86af6 [SCSI] aic94xx: asd_clear_nexus should fail if the cleared task does not complete
Every so often, the driver will call asd_clear_nexus to clean out a task.
It is supposed to be the case that the CLEAR NEXUS does not go on the done
list until after the task itself has been put on the done list, but for
some reason this doesn't always happen.  Thus, the
wait_for_completion_timeout call times out, and we return success.  This
makes libsas free the task even though the task hasn't completed, leading
to a BUG_ON message from aic94xx_hwi.c around line 341.  We should return
failure from asd_clear_nexus so that libsas tries again; at a bare minimum
it shouldn't be freeing active tasks.  I _think_ this will fix one of
the SCB timeout crash problems (though I've not been able to reproduce
it lately...)

Fix is to add a prototype for yyerror and mmerror to the relevant files.

1208bab5d0 [SCSI] aacraid: apply commit config for reset_devices flag
Under some conditions associated with the unclean transition to kdump,
the aacraid adapters will view the array as foreign and not export it to
prevent access and data manipulation. The solution is to submit a commit
configuration to export the devices since this is a expected behavior
when transitioning to a kdump kernel.

This patch adds the aacraid.reset_devices flag and when either this or
the global reset_devices flag is set, ensures that a commit config is
issued and extends the startup_timeout if it is set less than 5 minutes.

On digging into it, it turned out that the customer was probing an
aacraid device with an INQUIRY of 8 bytes.  The way aacraid works, it
was blindly trying to use aac_internal_transfer to copy the container
name to byte 16 of the inquiry data, resulting in a negative transfer
length.  It then copies over the whole of kernel memory before
dropping off the end.

http://bugzilla.kernel.org/show_bug.cgi?id=8469

As discussed in the bugzilla outlined below, we have an sa based
(Mustang) RAID adapter on the system, a Dell PERC2/QC. Affected
controllers are HP NetRAID, Adaptec AAC-364, Dell PERC2/QC or Adaptec
5400S. This problem  coincides with the introduction of the adapter_comm
and adapter_deliver platform functions (Message [PATCH 1/4] aacraid:
rework communication support code, January 23 2007, which initially
migrated to 2.6.21)

The panic occurs with an uninitialized adapter_deliver platform function
pointer. The enclosed patch, unmodified as tested by Rainer, solves the
problem.

d116a7bc6a [SCSI] stex: fix reset recovery for console device
After reset completed, the scsi error handler sends out TEST_UNIT_READY
to the device. For 'normal' devices the command will be handled by firmware.
However, because the RAID console only interfaces to scsi mid layer, the
firmware will not process the command for it. This will make the console to
be offlined right after reset. Add the handling in driver to fix this problem.

e0b2e597d5 [SCSI] stex: fix id mapping issue
The correct internal mapping of stex controllers should be:
id:0~15, lun:0~7 (st_shasta)
id:0, lun:0~127 (st_yosemite)
id:0~127, lun:0 (st_vsc and st_vsc1)

This patch reports the internal mapping to scsi mid layer,  eliminating
the translation between scsi mid layer and firmware. To achieve this
goal, we also need to:
-- fail the REPORT_LUNS command for st_shasta because the
   firmware is known to not report all actual luns
-- add an entry in scsi_devindo.c to force sequential lun scan
   (for st_shasta controllers)
-- fail the REPORT_LUNS command for console device
-- remove special handling of REPORT_LUNS command for
   st_yosemite, as there is no translation mapping now

9f28745a6b [SCSI] zfcp: IO stall after deleting and path checker changes after reenabling zfcp devices
IO stall after deleting and path checker changes after reenabling zfcp device

Setting one zfcp device offline using chccwdev in a multipath
environment and waiting will lead to IO stall on all paths.
After setting the zfcp device back online using chccwdev,
the devices with io stall will have a different path checker.
Devices corresponding to the deleted units are never freed.
This has the effect that 'slave_destroy' is never called and zfcp
still thinks that this unit is registered
(ZFCP_STATUS_UNIT_REGISTERED is still set). Hence the erp
routine is not called correctly and the unit is not enabled properly.

Do not delete rport and the sdev. Just set the host to block on
'offline'. Setting host online again will then remove the blocked status
and everything is fine again.

  - it didn't check for validity of id->eide_pio_modes and id->eide_pio_iordy
    before using them

  - it tried to found out maximum PIO mode basing on minimum IORDY cycle time
    (moreover wrong cycle times were used for PIO1/5)

  - it was overriding PIO blacklist and conservative PIO "downgrade" done
    by ide_get_best_pio_mode()

* use sis5513_tune_drive() instead of config_art_rwp_pio()
  in sis5513_config_xfer_rate() so the correct PIO mode is also set
  on drive even if the device is not IORDY/DMA capable

* config_art_rwp_pio() was always setting the best possible mode and not
  the wanted one - fix it and move ide_get_best_pio_mode() call to
  config_chipset_for_pio()

* don't use ide_find_best_mode() in config_chipset_for_pio(), it was being
  overriden by config_art_rwp_pio() for the host timings anyway + we need to
  set the same PIO mode on the device and the host

* pass correct "pio" argument (255 instead of 5) to sis5513_tune_drive() call
  in sis5513_config_xfer_rate() so the best PIO mode is set on the drive
  and not PIO4

* rename sis5513_tune_drive() to sis5513_tuneproc()
  and config_chipset_for_pio() to sis5513_tune_driver()

* bump driver version

9445de76c1 serverworks: PIO mode setup fixes
* limit max PIO mode to PIO4, this driver doesn't support PIO5 and attempt
  to program PIO5 by svwks_tune_chipset() could result in incorrect PIO
  timings being programmed and possibly the data corruption (it seems that
  the minimum possible values were used but I lack the datasheets to be sure)

* select best PIO mode in svwks_tune_drive() and not in svwks_tune_chipset()
  when doing PIO autotuning (pio == 255)

* don't try to tune PIO in config_chipset_for_dma() as ide_dma_enable() could
  return 1 if DMA was previously enabled (svwks_config_drive_xfer_rate()
  takes care of PIO tuning if no suitable DMA mode is found)

* remove config_chipset_for_pio() and use svwks_tune_drive() instead,
  config_chipset_for_pio() contained numerous bugs when selecting PIO mode
  (luckily it was only used for devices limited to PIO by capabilities/BIOS):

  - it didn't check for validity of id->eide_pio_modes and id->eide_pio_iordy
    before using them

  - it tried to found out maximum PIO mode basing on minimum IORDY cycle time
    (moreover wrong cycle times were used for PIO0/1/5)

  - it was overriding PIO blacklist and conservative PIO "downgrade" done
    by ide_get_best_pio_mode()

  - if the max drive PIO was PIO5 then XFER_PIO_0/XFER_PIO_SLOW was selected
    (XFER_PIO_SLOW is not supported by svwks_tune_chipset() so the result
     was the same as if using XFER_PIO_5 => wrong PIO timings were set)

  - it was overriding drive->current_speed

* bump driver version

4fce3164b8 pdc202xx_old: rewrite mode programming code (v2)
This patch is based on the documentation (I would like to thank Promise
for it) and also partially on the older vendor driver.

Rewrite mode programming code:

* disable 66MHz clock in pdc202xx_tune_chipset() so it is correctly disabled
  even if both devices on the channel are not DMA capable and after reset

* enable/disable IORDY and PREFETCH bits in pdc202xx_tune_chipset()
  as they need to be setup correctly also for PIO only devices, plus IORDY
  wasn't disabled for non-IORDY devices and PREFETCH wasn't disabled for
  ATAPI devices

* remove dead code for setting SYNC_ERDDY_EN bits from config_chipset_for_dma()
  (driver sets ->autotune to 1 so PIO modes are always programmed => lower
   nibble of register A never equals 4 => "chipset_is_set" is always true)

* enable PIO mode programming for all ATAPI devices
  (it was limited to ->media == ide_cdrom devices)

* remove extra reads of registers A/B/C, don't read register D et all

* do clearing / programming of registers A/B/C in one go
  (gets rid of extra PCI config space read/write cycle)

* set initial values of drive_conf/AP/BP/CP variables to zero
  (paranoia for the case when PCI reads fail)

* remove XFER_UDMA6 to XFER_UDMA5 remapping case - it can't happen
  (ide_rate_filter() takes care of it)

* fix XFER_MW_DMA0 timings (they were overclocked, use the official ones)

* fix bitmasks for clearing bits of register B:

  - when programming DMA mode bit 0x10 of register B was cleared which
    resulted in overclocked PIO timing setting (iff PIO0 was used)

  - when programming PIO mode bits 0x18 weren't cleared so suboptimal
    timings were used for PIO1-4 if PIO0 was previously set (bit 0x10)
    and for PIO0/3/4 if PIO1/2 was previously set (bit 0x08)

* add FIXME comment about missing locking for 66MHz clock register

Also while at it:

* remove unused defines

* do a few cosmetic / CodingStyle fixes

* bump driver version

v2:
* in pdc202xx_tune_chipset() the old content of drive configuration
  registers is used only by the debugging code so cover "drive_conf"
  PCI registers read by #if PDC202XX_DEBUG_DRIVE_INFO
  (Noticed by Sergei Shtylyov)

4e19b5c193 ucc_geth: eliminate max-speed, change interface-type to phy-connection-type
It was agreed that phy-connection-type was a better name for
the interface-type property, so this patch renames it.

Also, the max-speed property name was determined too generic,
and is therefore eliminated in favour of phy-connection-type
derivation logic.

includes corrections to copyright text.

Looks like the new version of this patch has been overlooked,
so I'm resending it.

It just adapts the driver to the new IRQ API

1af7f05628 pasemi_mac: Fix local-mac-address parsing
Turns out we have an old version of firmware that stores the mac address
in 'mac-address' as a string instead of a byte array. All versions that
use local-mac-address should have it as byte array, so no need to do
string parsing for that case.

faa8b6c3c2 Revert "ipmi: add new IPMI nmi watchdog handling"
This reverts commit f64da958df.

Andi Kleen is unhappy with the changes, and they really do not seem
worth it.  IPMI could use DIE_NMI_IPI instead of the new callback, even
though that ends up having its own set of problems too, mainly because
the IPMI code cannot really know the NMI was from IPMI or not.

Manually fix up conflicts in arch/x86_64/kernel/traps.c and
drivers/char/ipmi/ipmi_watchdog.c.

7c5b9ef857 IPoIB/cm: Optimize stale connection detection
In the presence of some running RX connections, we repeat
queue_delayed_work calls each 4 RX WRs, which is a waste.  It's enough
to start stale task when a first passive connection is added, and
rerun it every IPOIB_CM_RX_DELAY as long as there are outstanding
passive connections.

This removes some code from RX data path.

6c719f5c6c RDMA/cma: Add check to validate that cm_id is bound to a device
Several checks in the rdma_cm check against the state of the
cm_id, but only to validate that the cm_id is bound to an underlying
transport specific CM and an RDMA device.  Make the check explicit
in what we're trying to check for, since we're not synchronizing
against the cm_id state.

This will allow a user to disconnect a cm_id or reject a connection
after receiving a device removal event.

processing a new connection request to ensure that a device removal is
not already being processed for the same rdma_cm_id.  Without the state
check, the user can receive simultaneous callbacks for the same cm_id, or
a callback after they've destroyed the cm_id.
