3af9ca4d34 ata: libata-core: Improve link flags forced settings
Similarly to the horkage flags, introduce the force_lflag_onoff() macro
to define struct ata_force_param entries of the force_tbl array that
allow turning on or off a link flag using the libata.force boot
parameter. To be consistent with naming, the macro force_lflag() is
renamed to force_lflag_on().

Using force_lflag_onoff(), define a new force_tbl entry for the
ATA_LFLAG_NO_DEBOUNCE_DELAY link flag, thus allowing testing if an
adapter requires a link debounce delay or not.

5716fb0d40 ahci: Add a generic 'controller2' RAID id
Intel server platforms that support 'RAID', i.e. have platform firmware
support for software-RAID metadata + features that the kernel also
understands, maintain the same device-ids for RAID from generation to
generation. This is in contrast to client platforms that have tended to
roll new device-ids every platform generation. However, even though
server platform keep the ids there are still unique device-ids per
controller instance. To date there have only been 2 controllers on these
platforms, but platforms code named Emmitsburg add a third controller.

Add the device-id for this third controller and collect it with the
other generic server RAID ids.

As mentioned here [1], the pain of continuing add new and different
device-ids for RAID mode to this file [2] has been heard. Ideally this
device-id would not matter and the class code would remain
PCI_CLASS_STORAGE_SATA_AHCI regardless of the RAID mode, but other
operating systems depend on the class code *not* being AHCI when the
device is in RAID mode. That said, going forward there is little reason
for new server RAID ids to be added as they can simply reuse one of the
existing ids even for a new controller. Server software RAID features
continue to be supported on Linux. Client software RAID features
continue to be not supported and the recommendation there remains to set
the device to AHCI mode in platform firmware.

previously used copy propagation anyway...

The data transfer mode that corresponds to the 'xfer_mode' parameter for
ata_xfer_mode2shift() is a 8-bit *unsigned* value.  Using *unsigned long*

the 'u8' type instead, as in ata_xfer_mode2mask()...

4f1a22ee7b libata: Improve ATA queued command allocation
Improve ATA queued command allocation as follows:

- For attaining a qc tag for a SAS host we need to allocate a bit in
  ata_port.sas_tag_allocated bitmap.

  However we already have a unique tag per device in range
  [0, ATA_MAX_QUEUE -1] in the scsi cmnd budget token, so just use that
  instead.

- It is a bit pointless to have ata_qc_new_init() in libata-core.c since it
  pokes scsi internals, so inline it in ata_scsi_qc_new() (in
  libata-scsi.c). Also update Doc accordingly.

- Use standard SCSI helpers set_host_byte() and set_status_byte() in
  ata_scsi_qc_new().

Christoph Hellwig originally contributed the change to inline
ata_qc_new_init().

The reporter "Tice Rex" which has the unique opportunity that he
has two Samsung 840 EVO SSD! One with the older firmware "EXT0BB0Q"
which booted fine and didn't expose "READ LOG DMA EXT". But the
newer/latest firmware "EXT0DB6Q" caused the headaches.

the driver uses libata's "tag" values from in various arrays.
Since the mentioned patch bumped the ATA_TAG_INTERNAL to 32,
the value of the SATA_DWC_QCMD_MAX needs to account for that.

Otherwise ATA_TAG_INTERNAL usage cause similar crashes like
this as reported by Tice Rex on the OpenWrt Forum and
reproduced (with symbols) here:

This is because sata_dwc_dma_xfer_complete() NULLs the
dma_pending's next neighbour "chan" (a *dma_chan struct) in
this '32' case right here (line ~735):
> hsdevp->dma_pending[tag] = SATA_DWC_DMA_PENDING_NONE;

Then the next time, a dma gets issued; dma_dwc_xfer_setup() passes
the NULL'd hsdevp->chan to the dmaengine_slave_config() which then
causes the crash.

With this patch, SATA_DWC_QCMD_MAX is now set to ATA_MAX_QUEUE + 1.
This avoids the OOB. But please note, there was a worthwhile discussion
on what ATA_TAG_INTERNAL and ATA_MAX_QUEUE is. And why there should not
be a "fake" 33 command-long queue size.

Ideally, the dw driver should account for the ATA_TAG_INTERNAL.
In Damien Le Moal's words: "... having looked at the driver, it
is a bigger change than just faking a 33rd "tag" that is in fact
not a command tag at all."

d268afa1ff ata: pata_pxa: Use platform_get_irq() to get the interrupt
platform_get_resource(pdev, IORESOURCE_IRQ, ..) relies on static
allocation of IRQ resources in DT core code, this causes an issue
when using hierarchical interrupt domains using "interrupts" property
in the node as this bypasses the hierarchical setup and messes up the
irq chaining.

In preparation for removal of static setup of IRQ resource from DT core
code use platform_get_irq().

ce70fd9a55 scsi: core: Remove the cmd field from struct scsi_request
Now that each scsi_request is backed by a scsi_cmnd, there is no need to
indirect the CDB storage.  Change all submitters of SCSI passthrough
requests to store the CDB information directly in the scsi_cmnd, and while
doing so allocate the full 32 bytes that cover all Linux supported SCSI
hosts instead of requiring dynamic allocation for > 16 byte CDBs.  On
64-bit systems this does not change the size of the scsi_cmnd at all, while
on 32-bit systems it slightly increases it for now, but that increase will
be made up by the removal of the remaining scsi_request fields.

So remove AHCI_HFLAG_IGN_NOTSUPP_POWER_ON flag from Armada 3720 plat data.

manually disable the non-existing channel if the BIOS hasn't done this
already. Similarly to the pata_hpt3x2n driver, always disable the
primary channel.

In ata_sff_lost_interrupt(), wrap the ata_sff_altstatus() call in a

a58ff050b4 ata: pata_hpt366: disable fast interrupts in prereset() method
The PIO/DMA mode setting function is hardly a good place for disabling
the fast interrupts on a channel -- let's move that code to the driver's
prereset() method instead.

cf369e4e52 ata: pata_mpc52xx: use GFP_KERNEL
Platform_driver probe functions aren't called with locks held
and thus don't need GFP_ATOMIC. Use GFP_KERNEL instead.

Problem found with Coccinelle.

334bfa1f06 ata: sata_rcar: drop unused #define's
This driver has never used the SH-Navi2G/ATAPI-ATA compatible taskfile
registers (the driver uses the taskfile registers in another location
anyway), so drop their #define's...

f79ca4550c ata: pata_hpt366: check channel enable bits
HighPoint HPT36x chips did turn out to have the channel enable bits --
however, badly implemented. Make use of them, despite that is probably
only going to burden the driver's code -- assuming both channels are
always enabled by the HighPoint BIOS anyway...
