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. Signed-off-by:

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. Signed-off-by:Al Viro <viro@zeniv.linux.org.uk> Signed-off-by:

buf[i] can be up to 0xfd, so doubling it and assigning the result to an unsigned char truncates the value. Just use an unsigned int instead; it's only a temporary. Signed-off-by:

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.

Change PortAddr to be an unsigned int instead of an unsigned short (IO Port address are 24 bit on parisc). Fix a couple of printk argument warnings. Remove the Kconfig marking as 'BROKEN'. I haven't removed the #warning yet because virt_to_bus/bus_to_virt are only eliminated for narrow boards. Wide boards need more work. Signed-off-by:

Convert the call to virt_to_bus() into a call to dma_map_single(). Some architectures may require different DMA addresses for different devices, so allocate one overrun buffer per host rather than one for all cards. Signed-off-by:

Replace ASC_VADDR_TO_U32 and ASC_U32_TO_VADDR with an auto-expanding array that maps pointers to 32-bit IDs and back. One of the uses of ASC_VADDR_TO_U32 was in error; it should have been using ADV_VADDR_TO_U32. Also replace the use of virt_to_bus when setting the sense_address with a call to dma_map_single() followed by dma_cache_sync. This part cribbed from the 53c700 driver. Signed-off-by:

board->carrp is a duplicate of asc_dvc->carrier_buf, so cut out the middle-man and assign directly to carrier_buf. Move orig_reqp to adv_dvc too, since it's wide-board specific. Also eliminate an unnecessary BUG_ON (we'll never get there with a NULL carrier_buf, and will crash if we do). The bulk of this patch is rearranging structures so everything's declared in the right order. Signed-off-by:

Replace ASC_DBG{,1,2,3,4,5} with a single variadic macro ASC_DBG. As suggested by Jeff Garzik, include DRV_NAME and __FUNCTION__ in the output. Change all callers to no longer include the function name in the string. Enabling ADVANSYS_DEBUG to test this feature shows a lot of other problems that need to be fixed: - Reorder asc_prt_* functions now that their prototypes have been removed. - There is no longer a struct device in ASC_DVC_CFG/ADV_DVC_CFG, and it wasn't necessarily a PCI device to begin with. Print the bus_id from asc_board->dev instead. - isr_callback no longer exists. - ASC_DBG_PRT_SCSI_CMND isn't being used, so delete asc_prt_scsi_cmnd too. - A missing semicolon Signed-off-by: -

There were two blocks of ASC_IERR definitions; one for narrow and one for wide boards. Some of the same names were used (with the same values), and some of the same values were used with different names. This could only lead to confusion, so I unified them in one block of definitions with no overlapping values. Signed-off-by:

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. Signed-off-by:

The narrow board used two global structures to set up a command; unfortunately they weren't locked, so with two boards in the machine, one call to queuecommand could corrupt the data being used by the other call to queuecommand. Fix this by allocating asc_scsi_q on the stack (64 bytes) and using kmalloc for the asc_sg_head (2k) Signed-off-by:

- Replace ASC_ASSERT() with BUG_ON(). In a few places, get rid of the assertion altogether -- the ensuing crash will tell us all we need to know. Use BUG() where it fits better than BUG_ON(). Also fix a fencepost error in advansys_proc_info(). - Replace DvcSleepMilliSecond with mdelay. Despite its name using 'sleep', the implementation was a delay. I've marked some places with XXX where we should probably be using msleep instead. They need to be audited to be sure we can sleep in that context. - Replace DvcDelayMicroSecond with udelay. - Replace DvcDelayNanoSecond with udelay too. All callers were multiples of 1000. - Remove DvcEnterCritical and DvcLeaveCritical. These functions are no-ops, and as the comments said, the spinlock protects the critical sections. Signed-off-by:

AscExeScsiQueue() has one caller, and it passes the address of a variable; this cannot ever be NULL. This is the only place that ever sets ASCQ_ERR_SCSIQ_NULL_PTR, so delete that error code too, as well as several other unused ASCQ_ERR codes. Signed-off-by:

The SCSI midlayer won't send commands greater than ->max_cmd_len. So the checks on length in asc_build_req and adv_build_req are obsolete and can be deleted, but also we have to set the max_cmd_len in advansys_board_found().

The `active' list was used in the reset handler -- but the midlayer guarantees that list is empty by the time the reset handler is invoked. It was also checked in the interrupt routines to be sure that this command belonged to this board, but we don't need to check that either. We can then delete the asc_prt_target_stats() function as it will never print anything, along with asc_enqueue(), asc_dequeue_list(), asc_rmqueue(), asc_scsi_done_list(), struct asc_queue, ASC_QUEUE_EMPTY, ASC_TID_ALL, ASC_FRONT, ASC_BACK, and all the REQ* macros. Also remove this item from the todo list. Signed-off-by:

- Move the guts of asc_scsi_done_list() into a new function, asc_scsi_done. - Call asc_scsi_done() in asc_isr_callback() and adv_isr_callback(). The comment was wrong; scsi_done cannot enable interrupts. - All other places which queued an scp on the done list are error paths for queuecommand, and so we can just call asc_scsi_done() in queuecommand if we receive an error. - We no longer need to keep a list of done requests in advansys_interrupt Signed-off-by:
