After turning on DEBUG_SG I hit a fail:
kernel BUG at include/linux/scatterlist.h:50!
sg_build_indirect
sg_build_reserve
sg_open
chrdev_open
__dentry_open
do_filp_open
do_sys_open
We should initialise the sg list when we allocate it in sg_build_sgat.

Most drivers need to set length and offset as well, so may as well fold
those three lines into one.
Add sg_assign_page() for those two locations that only needed to set
the page, where the offset/length is set outside of the function context.

The original serial-number calculations based on WWPN no longer
apply to newer ISPs (ISP24xx and ISP25xx). These newer board's
serial number reside in the VPD.

For recent ISPs, software during CS_UNDERRUN handling must
determine if the two residuals, firmware-calculated and FCP_RSP,
are different to recognize if a frame has been dropped. Update
the driver to catch this condition, and clear the
SS_RESIDUAL_UNDER and lscsi_status bits. This logic is
consistent with what earlier firmwares did by explicitly
cracking open the FCP_RSP statuses and clearing
SS_RESIDUAL_UNDER.

Recent ISPs need only the single MMIO BAR to manipulate HW
registers. Unfortunately, ISP21xx, ISP22xx, ISP23xx, and ISP63xx
type cards still require the I/O mapped region to manipulate the
FLASH via the two HW flash-registers (flash_address and
flash_data).

Since both NVRAM and VPD regions of the flash reside on unaligned
sector boundaries, during update, the driver must perform a
read-modify-write operation to the composite NVRAM/VPD region.
This affects ISP25xx type boards only.

This structure is accessed by the device; the fewer Linux things in it,
the better. Using the pci_dev pointer from the hostdata requires a lot
of changes:
- Pass Scsi_Host to a lot of routines which currently take a sym_hcb.
- Set the Scsi_Host as the pci drvdata (instead of the sym_hcb)

By introducing the use_dac(), set_dac() and DMA_DAC_MASK macros, we can
eliminate a lot of ifdefs from the code. We now rely on the compiler to
optimise away a few things that we'd formerly relied on the preprocessor
to do. This makes sym_setup_bus_dma_mask() small enough to inline into
its only caller.

Instead of telling the reset routine that the command completed from
sym_eh_done, do it from sym_xpt_done. The 'to_do' element of the ucmd
is redundant -- it serves only to tell whether eh_done is valid or not,
and we can tell this by checking to see if it's NULL.

Before all commands used sg, data_mapping and data_mapped were used to
distinguish whether the command had used map_single or map_sg. Now all
commands are sg, so we can delete data_mapping, data_mapped and the

and map_scsi_sg_data.

i think there is wasted space in allocated pages for request and
response rings. The allocations are made with REQUEST_ENTRY_CNT + 1
and RESPONSE_ENTRY_CNT + 1, but they are set with 256 and 16.
So we got more pages, which we dont use very much so eliminate them.

The task_struct->pid member is going to be deprecated, so start
using the helpers (task_pid_nr/task_pid_vnr/task_pid_nr_ns) in
the kernel.
The first thing to start with is the pid, printed to dmesg - in
this case we may safely use task_pid_nr(). Besides, printks produce
more (much more) than a half of all the explicit pid usage.
