Add support for 32-byte READ/WRITE as well as DIF Type 2 protection.

enabled.

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.

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

The definition of the irq_ipi structure has two initializations of the
flags field.  This combines them.

[Ralf: The issue was originally introduced by commit
be4894196d79455f420dd7bb78be7dc73bec115c (linux-mips.org) rsp.
033890b0 (kernel.org).  The original
intention of the code was to initialize .flags with both flags ored together.
The broken C code as actually implemented will be compiled by an equally
broken gcc to use only the last initialization, that is IRQF_PERCPU
which means this turned into an SMTC bug for 2.6.23 and newer.]

The semantic match that finds this problem is as follows:
