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.

This patch fixes both issues by using be16_to_cpu().

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.

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.

fix an GFP_KERNEL allocation in atomic section: kvm_dev_ioctl_create_vcpu()
called kvm_mmu_init(), which calls alloc_pages(), while holding the vcpu.

The fix is to set up the MMU state in two phases: kvm_mmu_create() and
kvm_mmu_setup().

(NOTE: free_vcpus does an kvm_mmu_destroy() call so there's no need for any
extra teardown branch on allocation/init failure here.)

The latest version of kvm doesn't initialize kvm_arch_ops in kvm_init(), which
causes an error with the following sequence.

1. Load the supported arch's module.
2. Load the unsupported arch's module.$B!!(B(loading error)
3. Unload the unsupported arch's module.

You'll get the following error message after step 3.  "BUG: unable to handle
to handle kernel paging request at virtual address xxxxxxxx"

The problem here is that the unsupported arch's module overwrites kvm_arch_ops
of the supported arch's module at step 2.

This patch initializes kvm_arch_ops upon loading architecture specific kvm
module, and prevents overwriting kvm_arch_ops when kvm_arch_ops is already set
correctly.
