A repost of a patch forwarded by Mikael Reed from 2006-12-20.

The fibre channel IOC may kill a request for a variety of
reasons, some of which may be recovered by a retry, some of
which are unlikely to be recovered.  Return DID_ERROR
instead of DID_RESET to permit retry of the command,
just not an infinite number of them.

sr_block_ioctl() should proceed to SCSI ioctls if cdrom_ioctl()
returns -ENOSYS.  However it tested for ENOSYS instead of -ENOSYS
rendering all SCSI ioctls other than GET_IDLUN and GET_BUS_NUMBER
inaccessible.  Fix it.

Yanling Qi, noted that when the sense data length of
a check-condition is greater than 0x7f (127), senselen = (data[0] << 8)
| data[1] will become negative. It causes different kinds of panics from
GPF, spin_lock deadlock to spin_lock recursion.

We were also swapping this value on big endien machines.

Apparently no ATAPI CD/DVD actually supports REPORT LUNS (in spite of
claiming scsi-3 compliance, where it's mandatory) and worse, some
crash or flake out on being sent the command.  This may actually be
due to a conflict between SPC and MMC with MMC not listing REPORT LUNS
as mandatory.  The same standards conflict exists for RBC as well.

Fix all of this by reversing the blacklists for CDROM and RBC devices
(i.e. now they have to have the BLIST_REPORTLUNS2 flag set even if the
inquiry data returns scsi-3 compliance).

The code does this:

unsigned char sense[SCSI_SENSE_BUFFERSIZE];
...
scsi_normalize_sense(sense, sizeof(*sense), sshdr)

however the sizeof will return 1 not 96 which means the sense data will
have no valid ASC/ASCQ values.  Fix by putting the correct sense size.
The only affected case for this would have been the DV buffer sanity
check failure, which is fortunately quite rare.

If either scsi_complete_async_scans() is called a second time
before the first call has finished, or a host scan is started while
scsi_complete_async_scans() is still sleeping, it would fail to wake up
the other task, which would sleep forever.

I've changed the kernel-doc to make it clear that
scsi_complete_async_scans() only guarantees that scans which started
before it was called are guaranteed to have finished when it returns.
I considered making it wait until all scans are completed, but it can't
guarantee that no more scans will start before it returns anyway, and it
runs the risk of confusing other callers of scsi_complete_async_scans()
for hosts actually scanning.

Commit 968de4f0 ("i386: Relocatable
kernel support") caused problems for people with old binutils versions
that didn't mark ".text.*" sections automatically allocated.

So we should use .section command to specifically mark .text.head
section as AX (allocatable and executable) to solve the problem.

This should be unnecessary with binutils 2.15 and later, which is
already three years old, but it doesn't hurt supporting older toolchains
where possible.

Two issues:

- The final return 1 should be a return 0, otherwise comparing cfqq is
  a noop.

- bio_sync() only checks the sync flag, while rq_is_sync() checks both
  for READ and sync. The latter is what we want. Expand the bio check
  to include reads, and relax the restriction to allow merging of async
  io into sync requests.

In the future we want to clean up the SYNC logic, right now it means
both sync request (such as READ and O_DIRECT WRITE) and unplug-on-issue.
Leave that for later.

This is a slight variant on the patch I posted December 16th to fix
libata combined mode handling. The only real change is that we now
correctly also reserve BAR1,2,4. That is basically a neatness issue.

Jeff was unhappy about two things

1. That it didn't work in the case of one channel native one channel
legacy.

This is a silly complaint because the SFF layer in libata doesn't handle
this case yet anyway.

2. The case where combined mode is in use and IDE=n.

In this case the libata quirk code reserves the resources in question
correctly already.

Once the combined mode stuff is redone properly (2.6.21) then the entire
mess turns into a single pci_request_regions() for all cases and all the
ugly resource hackery goes away.

I'm sending this now rather than after running full test suites so that
it can get the maximal testing in a short time. I'll be running tests on
this after lunch.
