These interfaces:
pcibios_resource_to_bus(struct pci_dev *dev, *bus_region, *resource)
pcibios_bus_to_resource(struct pci_dev *dev, *resource, *bus_region)
took a pci_dev, but they really depend only on the pci_bus. And we want to
use them in resource allocation paths where we have the bus but not a
device, so this patch converts them to take the pci_bus instead of the
pci_dev:
pcibios_resource_to_bus(struct pci_bus *bus, *bus_region, *resource)
pcibios_bus_to_resource(struct pci_bus *bus, *resource, *bus_region)
In fact, with standard PCI-PCI bridges, they only depend on the host
bridge, because that's the only place address translation occurs, but
we aren't going that far yet.

This patch removes a bug in enlarge_buffer() that can make a
read or write fail under special conditions.
After changing TRY_DIRECT_IO to 0 and ST_MAX_SG to 32 in
st_options.h, a program that writes a first block of 128k and
than a second bigger block (e.g. 256k) fails. The second write
returns errno EOVERFLOW, as enlarge_buffer() checks the sg list
and detects that it already is full.
As enlarge_buffer uses different page allocation orders
depending on the size of the buffer needed, the check does not
make sense.

This patch includes change to enable firmware patch simplication
feature. This feature is targeted to address the requirement to have
independent patch release for firmware. Prior to 3.2.3, releasing a
patch fix for firmware requires changes to bfa, to use new firmware
images. But with these changes, if the new firmware is flashed on to the
HBA with brocade adapter management utilites, driver uses the new
firmware after checking the patch release byte in the firmware version.

The former minimum valid value of 'eh_deadline' is 1s, which means
the earliest occasion to shorten EH is 1 second later since a
command is failed or timed out. But if we want to skip EH steps
ASAP, we have to wait until the first EH step is finished. If the
duration of the first EH step is long, this waiting time is
excruciating. So, it is necessary to accept 0 as the minimum valid
value for 'eh_deadline'.
According to my test, with Hannes' patchset 'New EH command timeout
handler' as well, the minimum IO time is improved from 73s
(eh_deadline = 1) to 43s(eh_deadline = 0) when commands are timed
out by disabling RSCN and target port.

When a command runs into a timeout we need to send an 'ABORT TASK'
TMF. This is typically done by the 'eh_abort_handler' LLDD callback.
Conceptually, however, this function is a normal SCSI command, so
there is no need to enter the error handler.
This patch implements a new scsi_abort_command() function which
invokes an asynchronous function scsi_eh_abort_handler() to
abort the commands via the usual 'eh_abort_handler'.
If abort succeeds the command is either retried or terminated,
depending on the number of allowed retries. However, 'eh_eflags'
records the abort, so if the retry would fail again the
command is pushed onto the error handler without trying to
abort it (again); it'll be cleared up from SCSI EH.

Commit 18a4d0a22e
(Handle disk devices which can not process medium access commands)
was introduced to offline any device which cannot process medium
access commands.
However, commit 3eef6257de
(Reduce error recovery time by reducing use of TURs) reduced
the number of TURs by sending it only on the first failing
command, which might or might not be a medium access command.
So in combination this results in an erratic device offlining
during EH; if the command where the TUR was sent upon happens
to be a medium access command the device will be set offline,
if not everything proceeds as normal.
This patch moves the check to the final test, eliminating
this problem.

After getting warnings in an allyesconfig build[1] from this
driver, I decided to remind myself just how old it was, and
whether it warranted fixing. In the Kconfig help text, I found:
"This driver will eventually be phased out entirely"
Going back to the history archive, I see the line was added[2]
in Feb 2002, when we moved from v2.4.2.1 ---> v2.4.2.2
So, with over a decade of notification, and multiple major releases
since then, I think we can justify removing this. Currently we have
people wasting time building it during routine testing, and then
wasting more time re-researching the known reported warnings, only to
find that nobody really is willing to integrate the fixes[3] for it.
A quick search didn't seem to indicate any active user base for it.
If someone happens to have a quirky _old_ card that the eleven year
old "new" driver doesn't work with, then it is entirely reasonable
that they stick with a kernel version that predates this removal.
