and err path fixup from:
ogerlitz@voltaire.com
This patch cleans up that interface by having the lld and class
pass a iscsi_cls_session or iscsi_cls_conn between each other when
the function is used by HW and SW iscsi llds. This way the lld
does not have to remember if it has to send a handle or pointer
and a handle or pointer to connection, session or host.
This also has the class verify the session handle that gets passed from
userspace instead of using the pointer passed into the kernel directly.

Received From Mark Salyzyn.
In order to support user tools accessing the array components (SMART,
Mode Page information, Cache page adjustments, WWN determination,
Firmware updates etc), we take advantage of the no_uld_attach flag and
deprecate the code that filters Inquiries to block the requests to array
components. The quirk prevents the sd layer from attaching to the
components.
We also took the opportunity to balance the queue depths based on the
total adapter queue depth to the array devices to reduce the chances of
starvation.

This patch sets up some device quirks surrounding arrays to inform the
scsi layer that various mode pages are not supported. This reduces the
severity of the complaints that show up in the logs as the array devices
are enumerated.

I just purchased a HighPoint Rocket 1520 SATA controller. There seems to
be no libata driver (yet), but there is an ide driver, hpt366. When the
driver gets loaded, it causes a kernel NULL pointer dereference in
pci_bus_clock_list. It seems to be because the driver is waiting for clock
stabilization in init_hpt37x() which never comes. The driver just
continues on with the pci drvdata set to NULL, instead of a valid clock
entry. The following patch prevents the NULL dereference from happening,
but instead exit with an error.

This patch stops CompactFlash devices being marked as removable. They are
not removable (as defined by Linux) as the media and device are
inseparable. When a card is removed, the whole device is removed from the
system and never sits in a media-less state.
This stops some nasty udev device creation/destruction loops.
Further, once this change is made, there is no need for ide to can be
removed from ide_drive_t.

CONFIG_BLK_DEV_IDECS docu mentions everything and the kitchen sink, yet
fails to list the most important/widespread (IMHO) device: Compact Flash
PCMCIA adapters.
This incomplete description recently caused me to deselect the ide_cs
module, causing great pain soon thereafter when I realized why I had
actually enabled it some years ago.
Updates:
- make sure to mention Compact Flash adapters
- fix some random typos in ide Kconfig

There's no reason MAX_HWIFS needs to be ia64-specific, so set MAX_HWIFS

While looking to the report by Coverity in ipmi, I came across the
following issue:
The IPMI message handler relies on two defines which are the same -one in
include/linux/ipmi.h
#define IPMI_NUM_CHANNELS 0x10
and one in drivers/char/ipmi/ipmi_msghandler.
#define IPMI_MAX_CHANNELS 16
These are used interchangeably in ipmi_msghandler.c, but since the array
addr->channels[] is of size IPMI_MAX_CHANNELS, I have made a patch that
uses IPMI_MAX_CHANNELS for all the checks for the array index.
NOTE: You could probably remove the line that defines IPMI_NUM_CHANNELS
from ipmi.h, or move IPMI_MAX_CHANNELS to ipmi.h

With Eric's "i386: Add a temporary to make put_user more type safe" patch we
get a pile of warnings out of ip2m1in.c:
drivers/char/ip2main.c: In function `ip2_ipl_ioctl':
drivers/char/ip2main.c:2910: warning: assignment makes integer from pointer without a cast
drivers/char/ip2main.c:2911: warning: assignment makes integer from pointer without a cast
drivers/char/ip2main.c:2912: warning: assignment makes integer from pointer without a cast
etc.
This ioctl is copying the kernel virtual address of a large number of
functions out to userspace. Heaven knows why.
Rather than fixing the warnings, I think we'll just nuke that code.
The patch also fixes a couple of `defined but not used' warnings.
