James Smart 47a8617c7d [SCSI] lpfc 8.1.12 : Add support for async scanning
Add support for async scanning

Notes: This is the async scan patch to our driver from Matthew Wilcox.
  The async scan logic is still subject to errors in insmod/rmmod, as
  the async scan threads don't get shutdown when the module unloads
  underneath them. See http://marc.info/?l=linux-scsi&m=117551999925582&w=2

Brian King e555db930f [SCSI] use sysfs configured timeout for EH Start Unit timeout
Use the sysfs configurable timeout when issuing a START_UNIT
command from the scsi error handler. This is needed for devices which
take longer than thirty seconds to respond to the start
unit. The problem was observed when sending a start unit
to a disk array device in an ipr RAID adapter, which results
in the adapter firmware sending potentially multiple commands
to physical devices as a result of this command, which ended
up timing out sometimes. This patch does not change the default
value used for this command.

Bartlomiej Zolnierkiewicz 0e9b4e535f it821x: PIO mode setup fixes
* limit max PIO mode to PIO4, this driver doesn't support PIO5 and attempt
  to setup PIO5 by it821x_tuneproc() could result in incorrect PIO timings
  + incorrect base clock being set for controller in the passthrough mode

* move code limiting max PIO according to the pair device capabilities from
  config_it821x_chipset_for_pio() to it821x_tuneproc() so the check is also
  applied for mode change requests coming through ->tuneproc and ->speedproc
  interfaces

* set device speed in it821x_tuneproc()

* in it821x_tune_chipset() call it821x_tuneproc() also if the controller is
  in the smart mode (so the check for pair device max PIO is done)

* rename it821x_tuneproc() to it821x_tune_pio(), then add it821x_tuneproc()
  wrapper which does the max PIO mode check;  it worked by the pure luck
  previously, pio[4] and pio_want[4] arrays were used with index == 255
  so random PIO timings and base clock were set for the controller in the
  passthrough mode, thankfully PIO timings and base clock were corrected
  later by config_it821x_chipset_for_pio() call (but it was not called for
  PIO-only devices during resume and for user requested PIO autotuning)

* remove config_it821x_chipset_for_pio() call from config_chipset_for_dma()
  as the driver sets ->autotune to 1 and ->tuneproc does the proper job now

* convert the last user of config_it821x_chipset_for_pio() to use
  it821x_tuneproc(drive, 255) and remove no longer needed function

While at it:

* fix few comments

* bump driver version

of PIO5 to ide_get_best_pio_mode() despite supporting up to PIO4 only.

While at it, also:

- remove the driver's wrong claim about supporting SWDMA modes;

- stop hooking ide_dma_timeout() method as the handler clearly doesn't fit for
  the task...

mere call to it.
Start using faster versions of the ide_dma_end() and ide_dma_test_irq() methods
for the PCI0646U and newer chips that have the duplicate interrupt status bits
in the I/O mapped MRDMODE register, determing what methods to use at the driver
load time. Do some cleanup/renaming in the "old" ide_dma_test_irq() method too.

Sergei Shtylyov 5826b318aa cmd64x: procfs code fixes/cleanups (take 2)
Fix several issues with the driver's procfs output:

- when testing if channel is enabled, the code looks at the "simplex" bits, not
  at the real enable bits -- add #define for the primary channel enable bit;

- UltraDMA modes 0, 1, 3 for slave drive reported incorrectly due to using the
  master drive's clock cycle resolution bit.

While at it, also perform the following cleanups:

- don't print extra newline before the first controller's dump;

- correct the chipset names (from CMDxxx to PCI-xxx)

- don't read from the registers which aren't used for dump;

- better align the table column sizes;

- rework UltraDMA mode dump code;

- remove PIO mode dump code that has never been finished;

- remove the duplicate interrupt status (the MRDMODE register bits mirror those
  those in the CFR and ARTTIM23 registers) and fold the dump into single line;

- correct the style of the ?: operators...

Sergei Shtylyov 7accbffdb8 cmd64x: add/fix enablebits (take 2)
The IDE core looks at the wrong bit when checking if the secondary channel is
enabled on PCI0646 -- CNTRL register bit 7 is read-ahead disable, bit 3 is the
correct one.
Starting with PCI0646U chip, the primary channel can also be enabled/disabled --
so, add 'enablebits' initializers to each 'ide_pci_device_t' structure, handling
the original PCI0646 via adding the init_setup() method and clearing the 'reg'
field there if necessary...

Sergei Shtylyov e51e2528d5 cmd64x: interrupt status fixes (take 2)
The driver's ide_dma_test_irq() method was reading the MRDMODE register even on
PCI0643/6 where it was write-only -- fix this by always reading the "backward-
compatible" interrupt bits, renaming dma_alt_stat to irq_stat as the interrupt
status bits are not coupled to DMA.
In addition, wrong interrupt bit was tested/cleared for the primary channel --
it's bit 2 in all the chip specs and the driver used bit 1... :-/

Sergei Shtylyov 60e7a82f1a cmd64x: fix multiword and remove single-word DMA support
Fix the multiword DMA and drop the single-word DMA support (which nobody will
miss, I think).  In order to do it, a number of changes was necessary:

- rename program_drive_counts() to program_cycle_times(), pass to it cycle's
  total/active times instead of the clock counts, and convert them into the
  active/recovery clocks there instead of cmd64x_tune_pio() -- this causes
  quantize_timing() to also move;

- contrarywise, move all the code handling the address setup timing into
  cmd64x_tune_pio(), so that setting MWDMA mode wouldn't change address setup;

- remove from the speedproc() method the  bogus code pretending to set the DMA
  timings by twiddling bits in the BMIDE status register, handle setting MWDMA
  by just calling program_cycle_times(); while at it, improve the style of that
  whole switch statement;

- stop fiddling with the DMA capable bits in the speedproc() method -- they do
  not enable DMA, and are properly dealt with by the dma_host_{on,off} methods;

- don't set hwif->swdma_mask in the init_hwif() method anymore.

In addition to those changes, do the following:

- in cmd64x_tune_pio(), when writing to ARTTIM23 register preserve the interrupt
  status bit, eliminate local_irq_{save|restore}() around this code as there's
  *no* actual race with the interrupt handler, and move cmdprintk() to a more
  fitting place -- after ide_get_best_pio_mode() call;

- make {arttim|drwtim}_regs arrays single-dimensional, indexed with drive->dn;

- rename {setup|recovery}_counts[] into more fitting {setup|recovery}_values[];

- in  the speedproc() method, get rid of the duplicate reads/writes from/to the
  UDIDETCRx registers and of the extra variable used to store the transfer mode
  value after filtering,  use another method of determining master/slave drive,
  and cleanup useless parens;

- beautify cmdprintk() output here and there.

While at it, remove meaningless comment about the driver being used only on
UltraSPARC and long non-relevant RCS tag. :-)

Sergei Shtylyov 688a87d145 sl82c105: DMA support code cleanup (take 4)
Fold the now equivalent code in the ide_dma_check() method into a mere call to
ide_use_dma().  Make config_for_dma() return non-zero if DMA mode has been set
and call it from the ide_dma_check() method instead of ide_dma_on().
Defer writing the DMA timings to the chip registers until DMA is really turned
on (and do not enable IORDY for DMA).
Remove unneeded code from the init_hwif() method, improve its overall looks.
Rename the dma_start(), ide_dma_check(), and ide_dma_lostirq() methods, and
also use more proper hwif->dma_command, fix printk() and comment in the latter
one as well.  While at it, cleanup style in several places.

Sergei Shtylyov e93df705af sl82c105: rework PIO support (take 2)
Get rid of the 'pio_speed' member of 'ide_drive_t' that was only used by this
driver by storing the PIO mode timings in the 'drive_data' instead -- this
allows us to greatly  simplify the process of "reloading" of the chip's timing
register and do it right in sl82c150_dma_off_quietly() and to get rid of two
extra arguments to config_for_pio() -- which got renamed to sl82c105_tune_pio()
and now returns a PIO mode selected, with ide_config_drive_speed() call moved
into the tuneproc() method, now called sl82c105_tune_drive() with the code to
set drive's 'io_32bit' and 'unmask' flags in its turn moved to its proper place
in the init_hwif() method.
Also, while at it, rename get_timing_sl82c105() into get_pio_timings() and get
rid of the code in it clamping cycle counts to 32 which was both incorrect and
never executed anyway...

This patch removes the use of the TG3_FLAG_5701_REG_WRITE_BUG flag.
It's logic is only used to set a function pointer and thus the
logic can be collapsed and the flag removed.

Michael Chan 986e0aeb9a [TG3]: Remove reset during MAC address changes.
The reset was added a while back so that ASF could re-init whatever
MAC address it wanted to use after the MAC address was changed.
Instead of resetting, we can just keep MAC address 1 unchanged during
MAC address changes if MAC address 1 is different from MAC address 0.

This fixes 2 problems:

1. Bonding calls set_mac_address in contexts that cannot sleep.
It no longer sleeps with the chip reset removed.

2. When ASF shares the same MAC address as the NIC, it needs to
always do that even when the MAC address is changed.
