Most of the irq_req_t typedef'd struct can be re-worked quite
easily:
(1) IRQInfo2 was unused in any case, so drop it.
(2) IRQInfo1 was used write-only, so drop it.
(3) Instance (private data to be passed to the IRQ handler):
Most PCMCIA drivers using pcmcia_request_irq() to actually
register an IRQ handler set the "dev_id" to the same pointer
as the "priv" pointer in struct pcmcia_device. Modify the two
exceptions (ipwireless, ibmtr_cs) to also work this waym and
set the IRQ handler's "dev_id" to p_dev->priv unconditionally.
(4) Handler is to be of type irq_handler_t.
(5) Handler != NULL already tells whether an IRQ handler is present.
Therefore, we do not need the IRQ_HANDLER_PRESENT flag in
irq_req_t.Attributes.

__scsi_remove_device() in scsi_forget_host() is executed out of scan_mutex
and races with scsi_destroy_sdev() <- scsi_sysfs_add_devices() <-
scsi_finish_async_scan(). The result is use after free and/or double
free, oops.
The fix is simple, move scsi_forget_host() under scan_mutex.
scsi_forget_host() is just sequence of __scsi_remove_device(). All
another calls of __scsi_remove_device() are made under scan_mutex. So
that it is safe.

Async scanning introduced a very wide window where the SCSI device is
up and running but has not yet been added to sysfs. We delay the
adding until all scans have completed to retain the same ordering as
sync scanning.
This delay in visibility causes an oops if a device is removed before
we make it visible because the SCSI removal routines have an inbuilt
assumption that if a device is in SDEV_RUNNING state, it must be
visible (which is not necessarily true in the async scanning case).
Fix this by introducing an additional is_visible flag which we can use
to condition the tear down so we do the right thing for running but
not yet made visible.

Convert PCMCIA drivers to use the dynamic debug infrastructure, instead of
requiring manual settings of PCMCIA_DEBUG.
Also, remove all usages of the CS_CHECK macro and replace them with proper
Linux style calling and return value checking. The extra error reporting may
be dropped, as the PCMCIA core already complains about any (non-driver-author)
errors.

The root cause of the problem is the fact that dev_set_name() now
allocates storage instead of using the original array within the kobj.
That means that the SCSI assumption that if you haven't made the
containing object or any sub objects visible, you can just destroy it
(and its component devices) lock stock and barrel becomes false.
Fix this by doing the get of sdev_dev at parent time and thus do an
extra put of it in scsi_destroy_sdev() (and all other destruction
without add paths).

Current code attempts to clean up resources when queue create fails and there it
invokes queue free call with a (NULL) pointer to the queue which could not be

A memory use after free bug can manifest if the MTSETBLK or SET_DENS_AND_BLK
ioctl features are used to set the tape's blocksize from 0 to non-zero.
After the driver sets the new block size, in this one case it calls
normalize_buffer() to free the device's internal data buffers. However, the
ioctl code assumes there is always a buffer and does not check or allocate
a buffer if there isn't one. So any following ioctl calls can corrupt
a part of memory by writing data to memory that the st driver had freed.
This patch removes the normalize_buffer() call and the specialness of
changing from a 0 to non-zero blocksize to fix the possible use of
memory after it has been freed by the st driver.

firmware to ACK.
Following a diag_reset, a request to send an ioc_init is timing out. The
timeout occurred within the HANDSHAKE logic while waiting on firmware to
acknowledge that the driver had wrote to the doorbell register. This was
root caused to a logic timeout in the firmware code. The proposed solution
is for the driver to call the udelay instead of msleep API in function where
its looping reading the interrupt status. In addition to this change, there
were two additional cases where we deleted the clearing interrupt status
outside handshake context.

(1) Added three new functions to handle sending target resest and OP_REMOVE
from interrupt time, they are _scsih_tm_tr_send, _scsih_tm_tr_complete, and
_scsih_sas_control_complete. This code will create a link list of pending
target resets if there is no more available request in the hipriority
request queue. The list is stored in ioc->delayed_tr_list.
(2) All callback handler return type is changed from void to u8.
Now _base_interrupt will check for return type of callback handlers to
take decision of message frame is already freed or not.
In genral,
Return 1 meaning mf should be freed from _base_interrupt
0 means the mf is freed from function.

support multiple TM
1) create a pool of high priority message frames in the region of memory
between message frames and chains. The modifications are in
_base_allocate_memory_pools. Also create a seperate pool of memory for
internal commands located near the same region of memory. The pool of high
priority message frames is restriced by the facts->HighPriorityCredit.
2) Create additional API for accessing request message frames. New function
mpt2sas_base_get_smid_hpr is for highpriority request. New function
mpt2sas_base_get_smid_scsiio for SCSI_IO, passing in the scsi command
pointer. The mpt2sas_base_get_smid function is for requesting internal
commands.
3) Added new function _base_get_cb_idx to obtain the callback
index from one of the three pools of request message frames.
4) Removed wrapper functions _scsih_scsi_lookup_set and
_scsih_scsi_lookup_getclear. These were removed because this handling was
moved into mpt2sas_base_get_smid_scsiio and mpt2sas_base_free_smid.
5) The function mpt2sas_base_free_smid is modified so the request message
frames are put back on one of the three pools of request message frames.

Disks formatted with DIF Type 2 reject READ/WRITE 6/10/12/16 commands
when protection is enabled. Only the 32-byte variants are supported.
Implement support for issusing 32-byte READ/WRITE and enable Type 2
drives in the protection type detection logic.

We would leak a scsi_data_buffer if the free_list command was of the
protected variety.

So far we have only issued DIF commands if CONFIG_BLK_DEV_INTEGRITY is
enabled. However, communication between initiator and target should be
independent of protection information DMA. There are DIF-only host
adapters coming out that will be able to take advantage of this.
Move the relevant DIF bits to sd.c.

The checksum format is orthogonal to whether the protection information
is being passed on beyond the HBA or not. It is perfectly valid to use
a non-T10 CRC with WRITE_STRIP and READ_INSERT.
Consequently it no longer makes sense to explicitly refer to the
conversion in the protection operation. Update sd_dif and lpfc
accordingly.

A target reset when I/O is ongoing might result
an eventual device offline, as scsi_eh_completed_normally()
might return ADD_TO_MLQUEUE in addition to the
advertised SUCCESS, FAILED, and NEEDS_RETRY.
Which is unfortunate as scsi_send_eh_cmnd() will
therefore map ADD_TO_MLQUEUE to FAILED instead of
the more appropriate NEEDS_RETRY.

Running sg_luns on s390x with CONFIG_DEBUG_PAGEALLOC enabled fails
with EFAULT from the SG_IO ioctl. The EFAULT is the result from
copy_to_user failing in this call chain:
sg_ioctl
sg_new_read
sg_finish_rem_req
blk_rq_unmap_user
__blk_rq_unmap_user
bio_uncopy_user
__bio_copy_iov
copy_to_user
The sg driver calls sg_remove_scat to free the memory pages before
calling blk_rq_unmap_user that tries to copy the data back to
userspace. Change the order to first call blk_rq_unmap_user before
freeing the pages in sg_remove_scat.

On certain cases, UDF disc doesn't report capacity correctly via
READ_CAPACITY but TOC or trackinfo contains valid information which
can be obtained using cdrom_get_last_written(). ide-cd considers both
values and uses the larger one. Do the same in sr. This fixes
bko#9668.

5706/5708/5709 devices allow driver/user to set page size. By default it is
set to 4096. Current drivers do not program this register based on
architecture type (e.g. x86 = 4K, IA64 = 16K) and by choice lets device use
the defaults. So while mapping connection context memory (doorebll registers),
driver has to match page size used by the device. Included change fixes the
issue we uncovered during IA64 testing

Most code changes were made to support RR44xx adapters.
- add more PCI device ID.
- using PCI BAR[2] to access RR44xx IOP.
- using PCI BAR[0] to check and clear RR44xx IRQ.

The function mode_select_handle_sense returns SCSI_DH_OK even when there is a sense code which is incorrect. Removing it so that it returns SCSI_DH_IO when there is sense that is not handled by this function.
