logging support
This patch contains changes in mptfc.c, mptlan.c, mptsas.c and mptspi.c to
support logging in MPT fusion drivers.
The changes are majorly in debug printks, the existing debugprintk are
modified accroding to new debug macros defined in the file mptbdebug.h

addition of mptdebug.h
This patch adds a new file mptdebug.h in the fusion source directory,
which contains different debug macros. The existing debug macros and
flags are removed from the mptbase.h and Makefile In Kconfig a new
configuration parameter FUSION_LOGGING is added to enable/disable the
logging support during compile time.

Some of the code has been gradually transitioned to using the proper
struct request_queue, but there's lots left. So do a full sweet of
the kernel and get rid of this typedef and replace its uses with
the proper type.

Slab destructors were no longer supported after Christoph's
c59def9f222d44bb7e2f0a559f2906191a0862d7 change. They've been
BUGs for both slab and slub, and slob never supported them
either.
This rips out support for the dtor pointer from kmem_cache_create()
completely and fixes up every single callsite in the kernel (there were
about 224, not including the slab allocator definitions themselves,
or the documentation references).

This patch fixes access to memory that has not been allocated:
i2o_msg_get_wait() can returns errors different from I2O_QUEUE_EMPTY. But the
result is checked only against this code. If it is not I2O_QUEUE_EMPTY then
we dereference the error code as the pointer later.

This patch fixes a number of issues in i2o_cfg_passthru{,32}:
- i2o_msg_get_wait() return vaile is not checked;
- i2o_message memory leaks on error paths;
- infinite loop to sg_list_cleanup in passthru32
It's important issue because of i2o_cfg_passthru is used by raidutils for
monitorig controllers state, and in case of memory shortage it leads to the
node crash or disk IO stall.

If there is IO going to the volume while a hidden disk is being torn down,
there is a case where we would return a DID_NO_CONNECT for IO sent to the
volume. The end result is the volume goes read-only. This problem is due to the
fact the firmware mapped target ids saved in per device object is phys_disk_num
for hidden raid components, and target_id for the volume. There is a single
case when both phys_disk_num and target_id are equal, so enters this issue. We
fix this issue by checking the tflags when the device is torned down,
insuring the IO being completed is meant for hidden raid component, not the
volume. In addition to this fix, there are a couple other cases to address
hidden raid components. For instance task_abort and device reset are not
supported by mpt fw for hidden raid components, a bus reset would be required
or target reset to volume.

After host reset, the device are programmed to default asyn narrow nego.
We need to reprogram the parameter back to previous values. If the host
reset is called as a result of spi_dv_device() commands timing out, its
possible to get into an infinite loop of dv to host reset. This will
prevent that case, as we merely program old values. If host reset is
called outside context of domain validation, then we can call
spi_dv_device.

I2O subsystem has been broken in mainstream several months ago (after
2.6.18). Commit 4aff5e2333c9a1609662f2091f55c3f6fffdad36 from Jens
Axboe split struct request ->flags into two parts: cmd_type and
cmd_flags.
In i2o layer this patch has replaced flag REQ_SPECIAL by the according
cmd_type. However i2o has used REQ_SPECIAL not as command type but as
driver-specific flag for the debug purposes. As result all i2o requests
have type "special" now, are not processed to the hardware and fail with
I/O error:
i2o/hda:<3>Buffer I/O error on device i2o/hda, logical block 0
Buffer I/O error on device i2o/hda, logical block 0
Buffer I/O error on device i2o/hda, logical block 0
unable to read partition table
block-osm: device added (TID: 207): i2o/hda
The following patch removes the extra debug checks without any drawbacks and
restores the normal driver's work.
