The SCSI PRE-FETCH (10 or 16) command is present both on hard disks
and some SSDs. It is useful when the address of the next block(s) to
be read is known but it is not following the LBA of the current READ
(so read-ahead won't help). It returns two "good" SCSI Status values.
If the requested blocks have fitted (or will most likely fit (when
the IMMED bit is set)) into the disk's cache, it returns CONDITION
MET. If it didn't (or will not) fit then it returns GOOD status.
The goal of this patch is to stop the SCSI subsystem treating the
CONDITION MET SCSI status as an error. The current state makes the
PRE-FETCH command effectively unusable via pass-throughs.

The driver is very sloppy about the WQE structure passed between routines.
The base struct type is a 64byte wqe. But in many routines they typecast and
access 128byte wqes. There were a couple of cases in the past (corrected
already) where the typecasts were incorrectly done and the 64byte buffer was
accessed as a 128 byte buffer.
Clean this up by properly declaring wqe's as 128byte wqe's and removing the
typecasts. 64byte wqes are considered a subset of the 128byte wqes.

Commit 1351e69fc6 ("scsi: lpfc: Add push-to-adapter support to sli4")
fails compilation on some 32-bit systems as writeq() is not supported on
all architectures. Additionally, it was pointed out that as writeX()
does byteswapping if necessary for pci vs the cpu endianness, the code
was broken on BE PPC.
After discussions with Arnd Bergmann, we've resolved the issue
to the following:
Instead of writeX(), use __raw_writeX() - which writes to io
space while preserving byte order. To use this, the code
was changed to use a different buffer that lpfc prepped
via sli_pcimem_bcopy() that was set to the bytestream to
be written.
On platforms with __raw_writeq support, use the routine, otherwise
use __raw_writel()

Both dma_addr_t and phys_addr_t may be wider than a pointer, so we must
avoid the conversion to pointer types. This also helps readability.
A second problem is treating MMIO addresses from a 'struct resource'
as addresses that can be used for DMA on that device. In almost all
cases, those are the same, but on some of the more obscure architectures,
PCI memory address 0 is mapped into the CPU address space at a nonzero
offset. I don't have a good fix for that, so I'm adding a comment here,
plus a WARN_ON() that triggers whenever the phys_addr_t number is
outside of the low 32-bit address space and causes a straight overflow
when assigned to the 32-bit sgel->Address.
