Arjan van de Ven 25729a7fb8 [SCSI] advansys, arcmsr, ipr, nsp32, qla1280, stex: use pci_ioremap_bar()
Use the newly introduced pci_ioremap_bar() function in drivers/scsi.
pci_ioremap_bar() just takes a pci device and a bar number, with the goal
of making it really hard to get wrong, while also having a central place
to stick sanity checks.

Al Viro 30037818f7 advansys fix on ISA-less configs
The code

        if (shost->dma_channel != NO_ISA_DMA)
                free_dma(shost->dma_channel);

in there is triggerable only if we have CONFIG_ISA (we only set ->dma_channel to
something other than NO_ISA_DMA under #ifdef CONFIG_ISA).  OTOH, free_dma() is
not guaranteed to be there in absense of CONFIG_ISA.  IOW, driver runs into
undefined symbols on PCI-but-not-ISA configs (e.g. on frv) and it's a false
positive.

Fix: put the entire if () under #ifdef CONFIG_ISA; behaviour doesn't change and
dependency on free_dma() disappears for !CONFIG_ISA.

FUJITA Tomonori 7d5d408c77 [SCSI] advansys: fix overrun_buf aligned bug
struct asc_dvc_var needs overrun buffer to be placed on an 8 byte
boundary. advansys defines struct asc_dvc_var:

struct asc_dvc_var {
	...
	uchar overrun_buf[ASC_OVERRUN_BSIZE] __aligned(8);

The problem is that struct asc_dvc_var is placed on
shost->hostdata. So if the hostdata is not on an 8 byte boundary, the
advansys crashes. The hostdata is placed on a sizeof(unsigned long)
boundary so the 8 byte boundary is not garanteed with x86_32.

With 2.6.23 and 2.6.24, the hostdata is on an 8 byte boundary by
chance, but with the current git, it's not.

This patch removes overrun_buf static array and use kzalloc.

 - There is no longer a struct device in ASC_DVC_CFG/ADV_DVC_CFG, and it

Matthew Wilcox d361db4832 [SCSI] advansys: Sort out irq number mess
The interrupt number was being stored in 4-5 different places, each with
its own type, rules and usage.  Fix this by keeping an unsigned int in
the struct asc_board, and filling it in from the bus probe functions
(since it's different for each of the four bus types).  In order to do
this, we have to allocate the Scsi_Host in the bus probe functions too.
Then we can return an error from advansys_board_found, which requires
a little rearranging of code (and removing of the err_code variable).
Move the Wide Board flag setting into the PCI bus probe function.

Split the AscGetChipIRQ function into three functions (one for each bus
type that needs it) and add some commentary to explain what's going on.
Also get rid of the AscSetChipIRQ function as we only ever set the
interrupt number to the same value it already had.

It's just data, so format it to something that looks more visually
appealing (and saves some lines)

Matthew Wilcox b8e5152bf1 [SCSI] advansys: Fix VLB driver name
You can't have two drivers for the same bus type with the same name.
Since ISA and VLB are both isa_drivers, rename the VLB one to advansys_vlb.

Matthew Wilcox 4bd6d7f356 [SCSI] advansys: Move documentation to Documentation/scsi
The 700+-line comment at the top of the advansys driver fits more comfortably
in Documentation/scsi.

Delete the sections on:
 - kernels supported
 - other files modified (obsolete)
 - source comments (obsolete)
 - tests to run
 - release history (that's what a VCS is for)
 - contacting connectcom (the domain has expired and the phone number is
   now in use by another organisation)

Known problems/fix list is moved down to the section where jejb put his FIXME.

Matthew Wilcox d68f432135 [SCSI] advansys: use memcpy instead of open-coded loop
Use memcpy to initialise eep_config instead of a loop.  For
AdvInitFrom38C1600EEP where we need to modify the default EEPROM
configuration, do it after the loop, and do it using the structure
definition, not by finding the right byte.  I think it was wrong for
big-endian machines.

Also delete some non-useful comments and prototypes.

Matthew Wilcox 13ac2d9c79 [SCSI] advansys: Remove pci_slot_info
The driver kept a copy of the PCI config address; refer to the pci_dev
associated with the card instead.
