Mauro Carvalho Chehab cd238effef docs: kbuild: convert docs to ReST and rename to *.rst
The kbuild documentation clearly shows that the documents
there are written at different times: some use markdown,
some use their own peculiar logic to split sections.

Convert everything to ReST without affecting too much
the author's style and avoiding adding uneeded markups.

The conversion is actually:
  - add blank lines and identation in order to identify paragraphs;
  - fix tables markups;
  - add some lists markups;
  - mark literal blocks;
  - adjust title markups.

At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

This is mostly update of the usual drivers: arcmsr, qla2xxx, lpfc,

 refactored gdth as part of the dma changes.  The major mid-layer
 change this time is the removal of bidi commands and with them the

Finn Thain 83d2aed444 scsi/atari_scsi: Don't select CONFIG_NVRAM
On powerpc, setting CONFIG_NVRAM=n builds a kernel with no NVRAM support.
Setting CONFIG_NVRAM=m enables the /dev/nvram misc device module without
enabling NVRAM support in drivers. Setting CONFIG_NVRAM=y enables the
misc device (built-in) and also enables NVRAM support in drivers.

m68k shares the valkyriefb driver with powerpc, and since that driver uses
NVRAM, it is affected by CONFIG_ATARI_SCSI, because of the use of
"select NVRAM". We can avoid the "select" here, but drivers still have
to interpret the CONFIG_NVRAM symbol consistently regardless of platform.

In this patch and the subsequent fbdev driver patch, the convention is
adopted across all relevant platforms whereby NVRAM functionality gets
enabled in a given device driver when the nvram misc device is built-in
or when both drivers are modules.

Arnd Bergmann a3ecf48248 scsi: myrs: only build on little-endian platforms
Reading throught the new driver, I noticed that this cannot work on
big-endian CPUs, and the old DAC960 had exactly the same behavior.

To document this for the future, add a Kconfig dependency that prevents it
from being included in big-endian kernels.  Since the hardware is really
old and we never had a working driver on it for big-endian platforms,
it's unlikely to make a difference to users.

Michael Schmitz 3109e5ae03 scsi: zorro_esp: New driver for Amiga Zorro NCR53C9x boards
New combined SCSI driver for all ESP based Zorro SCSI boards for m68k Amiga.

Code largely based on board specific parts of the old drivers (blz1230.c,
blz2060.c, cyberstorm.c, cyberstormII.c, fastlane.c which were removed after
the 2.6 kernel series for lack of maintenance) with contributions by Tuomas
Vainikka (TCQ bug tests and workaround) and Finn Thain (TCQ bugfix by use of
PIO in extended message in transfer).

New Kconfig option and Makefile entries for new Amiga Zorro ESP SCSI driver
included in this patch.

Use DMA transfers wherever possible, with board-specific DMA set-up functions
copied from the old driver code. Three byte reselection messages do appear to
cause DMA timeouts. So wire up a PIO transfer routine for these
instead. esp_reselect_with_tag explicitly sets
esp->cmd_block_dma as target address for the message bytes but PIO
requires a virtual address.  Substiute kernel virtual address
esp->cmd_block in PIO transfer call if DMA address is esp->cmd_block_dma
and phase is message in.

PIO code taken from mac_esp.c where the reselection timeout issue was debugged
and fixed first, with minor macro and function rename.

Without CONFIG_BLK_DEV_BSGLIB, we get a link error here:

This modifies the Kconfig 'select' statement accordingly, and matching
what we do for the other two scsi_transport implementations that use
bsglib.

Christoph Hellwig cbe7dfa26e Revert "scsi: default to scsi-mq"
Defaulting to scsi-mq in 4.13-rc has shown various regressions
on setups that we didn't previously consider.  Fixes for them are
in progress, but too invasive to make it in this cycle.  So for
now revert the commit that defaults to blk-mq for SCSI.  For 4.14
we'll plan to try again with these fixes.

This reverts commit 5c279bd9e4.

Arnd Bergmann cd069bb9f9 scsi: lpfc: fix linking against modular NVMe support
When LPFC is built-in but NVMe is a loadable module, we fail to link the
kernel:

drivers/scsi/built-in.o: In function `lpfc_nvme_create_localport':
(.text+0x156a82): undefined reference to `nvme_fc_register_localport'
drivers/scsi/built-in.o: In function `lpfc_nvme_destroy_localport':
(.text+0x156eaa): undefined reference to `nvme_fc_unregister_remoteport'

We can avoid this either by forcing lpfc to be a module, or by disabling
NVMe support in this case. This implements the former.

James Smart 7d7080335f scsi: lpfc: Finalize Kconfig options for nvme
Reviewing the result of what was just added for Kconfig, we made a poor
choice. It worked well for full kernel builds, but not so much for how
it would be deployed on a distro.

Here's the final result:
- lpfc will compile in NVME initiator and/or NVME target support based
  on whether the kernel has the corresponding subsystem support.
  Kconfig is not used to drive this specifically for lpfc.
- There is a module parameter, lpfc_enable_fc4_type, that indicates
  whether the ports will do FCP-only or FCP & NVME (NVME-only not yet
  possible due to dependency on fc transport). As FCP & NVME divvys up
  exchange resources, and given NVME will not be often initially, the
  default is changed to FCP only.
