drivers/message/i2o/i2o_block.c: In function 'i2o_block_transfer':
drivers/message/i2o/i2o_block.c:837: warning: integer overflow in expression
msg->u.head[1] = cpu_to_le32(I2O_CMD_PRIVATE << 24 | HOST_TID << 12 | tid);
and I2O_CMD_PRIVATE is defined as 0xFF. This gets "0xFF0100 | tid" and fits
into 32-bit unsigned but not into 32-bit signed integer properly. Target
value is defined as u32 so the claculation does not fit during computation.
Change local variable tid to u32 so the whole expression is of u32 type and
fits well into u32 result.

This rips out support for the dtor pointer from kmem_cache_create()

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.
