order in which they are defined in the header. this makes is easier

* Remove in-source changelog. It's archived permanently in git and
various kernel archives, and changelogs should exist purely in git.
* Remove 2.4.x kernel support. It is an active obstacle to
modernizing this driver, at this point. This includes killing
gdth_kcompat.h which is 100% redundant in modern kernels.

Rather than having internal commands abuse scsi_done to call
gdth_scsi_done, have all the places that use to call scsi_done directly
call gdth_scsi_done, which now checks whether the command was internal,
and calls scsi_done if not.

REQUEST_SENSE
- Drivers/transports that want to send a synchronous REQUEST_SENSE command
as part of their .queuecommand sequence, have 2 new API's that facilitate
in doing so and abstract them from scsi-ml internals.
void scsi_eh_prep_cmnd(struct scsi_cmnd *scmd,
struct scsi_eh_save *sesci, unsigned char *cmnd,
int cmnd_size, int sense_bytes)
Will hijack a command and prepare it for request sense if needed.
And will save any later needed info into a scsi_eh_save structure.
void scsi_eh_restore_cmnd(struct scsi_cmnd* scmd,
struct scsi_eh_save *sesci);
Will undo any changes done to a command by above function. Making
it ready for completion.
- Re-factor scsi_send_eh_cmnd() to use above APIs

Fix section mismatch in the Adaptec DPT SCSI Raid driver.
WARNING: vmlinux.o(.init.text+0x1fcd2): Section mismatch:
reference to .exit.text:adpt_exit (between 'adpt_init' and 'ahc_linux_init')
This warning is due to adaptec device detection calling the exit routine on
failure to properly register the adaptec device.
The exit routine + call was added on July 30 by
Commit: 55d9fcf57ba5ec427544fca7abc335cf3da78160
Author: Matthew Wilcox
Subject: [SCSI] dpt_i2o: convert to SCSI hotplug model.
Mathew: isn't a module exit routine a little too strong to be calling on the
failure of a single device? Module exit implies that other, non-failing
adaptec raid devices will also get shut down.

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.

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

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.

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.

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.

for the asc_sg_head (2k)

The ULD ->done callback moves into the scsi_driver. By moving the call
to scsi_io_completion() from scsi_blk_pc_done() to scsi_finish_command(),
we can eliminate the latter entirely. By returning 'good_bytes' from
the ->done callback (rather than invoking scsi_io_completion()), we can
stop exporting scsi_io_completion().
Also move the prototypes from sd.h to sd.c as they're all internal anyway.
Rename sd_rw_intr to sd_done and rw_intr to sr_done.

Because scsi_print_sense_hdr prefixes with KERN_INFO, the output from
scsi_io_completion looks like:
sd 0:0:0:0: [sdb] Device not ready: <6>: Sense Key : 0x2 [current]
: ASC=0x4 ASCQ=0x3
By using scsi_show_sense_hdr, we can get the much more appealing output:
sd 0:0:0:0: [sdb] Device not ready: Sense Key : 0x2 [current]
sd 0:0:0:0: [sdb] Device not ready: ASC=0x4 ASCQ=0x3
