This patch modifies scsi_host_template->change_queue_depth so that
it takes an argument indicating why it is being called. This will be
used so that if a LLD needs to do some extra processing when
handling queue fulls or later ramp ups, it can do so.
This is a simple port of the drivers setting a change_queue_depth
callback. In the patch I just have these LLDs adjust the queue depth
if the user was requesting it.

[Vasu.Dev: v2
Also converted pmcraid_change_queue_depth and then verified
all modules compile using "make allmodconfig" for any new build
warnings on X86_64.
Updated original description after combing two original
patches from Mike to make this patch git bisectable.]

adding/removing the devices from FW
Driver will update the OS devices after adding and deleting the device
from FW. When driver receive add or delete AEN from FW, driver will
send the DCMD cmd to get the System PD list from FW. Then driver will
check if this device already in the OS: If add event and OS don't have
the device (but it is in the list), driver add the device to OS,
otherwise driver will not add. If remove event, driver will check the
list, if is not in the list, but OS have the device, driver will
remove the device.

As it is, all instances of ->release() for files that have ->fasync()
need to remember to evict file from fasync lists; forgetting that
creates a hole and we actually have a bunch that *does* forget.
So let's keep our lives simple - let __fput() check FASYNC in
file->f_flags and call ->fasync() there if it's been set. And lose that
crap in ->release() instances - leaving it there is still valid, but we
don't have to bother anymore.

Right now SCSI and others do their own command timeout handling.
Move those bits to the block layer.
Instead of having a timer per command, we try to be a bit more clever
and simply have one per-queue. This avoids the overhead of having to
tear down and setup a timer for each command, so it will result in a lot
less timer fiddling.

/sys/bus/pci/drivers/megaraid_sas/dbg_lvl defaults to being
world-writable, which seems bad (letting any user affect kernel driver
behavior and logging level).
This turns off group and user write permissions, so that on typical
production systems only root can write to it.

Newer Dell CERC firmware (>= 6.62) implement a random deletion handling
compatible with the legacy megaraid driver. The legacy handling shifted
the target ID by 0x80 only for I/O commands (READ/WRITE/etc), whereas
megaraid_mbox shifts the target ID always if random deletion is supported.
The resulted in megaraid_mbox sending an INQUIRY to the wrong channel, and
not finding any devices, obviously.
So we disable the random deletion support if the offending firmware is
found.

The MegaRAID driver's common management module (megaraid_mm.c) creates a
char device used by the management tool "megarc" from LSI Logic (and
possibly other management tools).
In 2.6 with udev, this device doesn't get created because it is not
registered in sysfs.
I first fixed this by registering a class "megaraid_mm", but realized that
this should probably be moved to misc devices, instead of taking up a char
major. This is because only 1 device is used, even if there are multiple
adapters - the minor is never used (the adapter info is in the ioctl block
sent to the driver, not detected based on the minor number as one might
think). So it is a complete waste to have an entire major taken by this.
So it now uses a misc device which I named "megadev0" (the name that megarc
expects), and has a dynamic minor (previoulsy a dynamic major was used).
I have tested this on my own system with the megarc tool, and it works just
as fine as before (only now the device gets created correctly by udev).

With the sg table code, every SCSI driver is now either chain capable
or broken (or has sg_tablesize set so chaining is never activated), so
there's no need to have a check in the host template.
Also tidy up the code by moving the scatterlist size defines into the
SCSI includes and permit the last entry of the scatterlist pools not
to be a power of two.

Added module parameter "poll_mode_io" to support for "polling"
(reduced interrupt operation). In this mode, IO completion interrupts
are delayed. At the end of initiating IOs, the driver schedules for
cmd completion if there are pending cmds. A timer-based interrupt has
also been added to prevent IO completion from being delayed
indefinitely in the case that no new IOs are initiated. Some
formatting issues in resume, suspend comment block also corrected
