Seems that the CS5530A chip used in Geode GX1 systems has some crazy feature
that causes SMI traps when accessing the PCI configuration space of the video
device.  Various GX1 BIOSes seem to use this 'feature' to hide the real BARs
of the device.  This patch disables these traps (in an early PCI fixup) so
that Linux sees the real, physical BARs and not the virtual ones provided by
the BIOS.

This should allow the GX1 framebuffer driver to work on more systems that have
different BIOSes as the driver no longer guesses at what the virtual BARs
mean.

I'm not entirely sure it the correct solution as I can neither test regular
VGA console nor the X's 'cyrix' video driver so there might be some breakage

[PATCH] dell_rbu: fix Bug 5854

This fixes http://bugzilla.kernel.org/show_bug.cgi?id=5854

Root cause:

The dell_rbu driver creates entries in /sys/class/firmware/dell_rbu/ by
calling request_firmware_nowait (without hotplug ) this function inturn
starts a kernel thread which creates the entries in
/sys/class/firmware/dell_rbu/loading , data and the thread waits on the
user action to return control back to the callback fucntion of dell_rbu.
The thread calls wait_on_completion which puts it in a D state until the
user action happens.  If there is no user action happening the load average
goes up as the thread D state is taken in to account.  Also after
downloading the BIOS image the enrties go away momentarily but they are
recreated from the callback function in dell_rbu.  This causes the thread
to get recreated causing the load average to permenently stay around 1.

Fix:

The dell_rbu also creates the entry
/sys/devices/platform/dell_rbu/image_type at driver load time.  The image
type by default is mono if required the user can echo packet to image_type
to make the BIOS update mechanism using packets.  Also by echoing init in
to image_type the /sys/class/firmware/dell_rbu entries can be created.

The driver code was changed to not create /sys/class/firmware/dell_rbu
entries during load time, and also to not create the above entries from the
callback function.  The entries are only created by echoing init to
/sys/devices/platform/dell_rbu/image_type The user now needs to create the
entries to download the image monolithic or packet.  This fixes the issue
since the kernel thread only is created when ever the user is ready to
download the BIOS image; this minimizes the life span of the kernel thread
and the load average goes back to normal.

  http://bugzilla.kernel.org/show_bug.cgi?id=5859

and by various other email messages and lkml posts is that the cpuset hook
in the oom (out of memory) code can try to take a cpuset semaphore while
holding the tasklist_lock (a spinlock).

One must not sleep while holding a spinlock.

The fix seems easy enough - move the cpuset semaphore region outside the
tasklist_lock region.

This required a few lines of mechanism to implement.  The oom code where
the locking needs to be changed does not have access to the cpuset locks,
which are internal to kernel/cpuset.c only.  So I provided a couple more
cpuset interface routines, available to the rest of the kernel, which
simple take and drop the lock needed here (cpusets callback_sem).

[PATCH] Add tmpfs options for memory placement policies

Anything that writes into a tmpfs filesystem is liable to disproportionately
decrease the available memory on a particular node.  Since there's no telling
what sort of application (e.g.  dd/cp/cat) might be dropping large files
there, this lets the admin choose the appropriate default behavior for their
site's situation.

Introduce a tmpfs mount option which allows specifying a memory policy and
a second option to specify the nodelist for that policy.  With the default
policy, tmpfs will behave as it does today.  This patch adds support for
preferred, bind, and interleave policies.

The default policy will cause pages to be added to tmpfs files on the node
which is doing the writing.  Some jobs expect a single process to create
and manage the tmpfs files.  This results in a node which has a
significantly reduced number of free pages.

With this patch, the administrator can specify the policy and nodes for
that policy where they would prefer allocations.

This patch was originally written by Brent Casavant and Hugh Dickins.  I
added support for the bind and preferred policies and the mpol_nodelist
mount option.

[PATCH] Watchdog: Winsystems EPX-C3 SBC

This is a 2.6 patch that adds support for the watchdog timer built into the
EPX-C3 single board computer manufactured by Winsystems, Inc.

Driver details:

This is for x86 only.  This watchdog is pretty basic and simple.  It is
only configurable via jumpers on the SBC, and it only has either a 1.5s or
200s interval.  The watchdog can either be auto-configured to start as soon
as the machine powers up (bad idea for the 1.5s interval!) or it can be
enabled and disabled by writing to io port 0x1ee.  Petting the watchdog
involves writing any value to io port 0x1ef.

The only unfortunate thing about this watchdog (and it is not at all
uncommmon in watchdogs that linux supports) is that it is not a PCI or
ISA-PNP device and as such it isn't at all probeable.  Either the watchdog
exists as 2 bytes at 0x1ee, or it doesn't.  Thus, using this driver on a
machine that doesn't have that watchdog can potentially hang/crash the
system, etc.  So only use this driver if you in fact are on a Winsystems
EPX-C3 SBC.

Anyway this driver fits into the already-existing watchdog framework quite
nicely and I already tested it on my EPX-C3 and it works like a charm.

Fixed the refcounting on failure exits in sys_mq_open() and

Fix consists of making the rules for do_create() and do_open()
same as for dentry_open() and updating the sys_mq_open() accordingly;

[SCSI] qla2xxx: Correct excessive delay during LOAD-RISC-RAM mailbox command.

Problem report (against 2.4.x driver) from Jeff Layton
<jlayton@redhat.com>:

An OEM noticed that the U6 qla2200 driver would hang for
around 2 minutes at boot time and then proceed normally. I
found that the delay was occurring when loading the new
firmware into the card, and was due to a
schedule_timeout(10) added to the bottom of the polling
loop.

Some testing showed that the load ram operation on the card
was very quick (on the order of a couple of jiffies), but
the sleep in the polling loop was making each operation take
around 25-30.

The attached patch corrects this by making it skip sleeping
during the load ram operation, since I believe we only do
that when the module is plugged in. It also skips sleeping
if the mbox_int flag got set during the current loop.

This corrected the hang on my test setup, and OEM also
confirmed that it corrected the problem for them.

Instead of doing the lib, I just kept everything in scsi_trnapsort_iscsi.c
like the FC and SPI class. This was becuase the driver model and sysfs
class is tied to the session and connection setup so separating did not
buy very much at this time.

use the iscsi class becuase the scsi_host was tied to the interface and
class code. This patch just seperates the session from scsi host so
that LLDs that allocate the host per some resource like pci device
can still use the class.

So this patch adds a user_scan attribute instead, that takes over from
scsi_scan_host_selected if the transport class sets it and thus lets
the transport class control the user-initiated scanning.  As this
plugs the hole about user-initiated scanning the target_parent hook
goes away and we rely on callers of the scanning routines to do
something sensible.

For SAS this meant I had to switch from a spinlock to a mutex to
synchronize the topology linked lists, in FC they were completely
unsynchronized which seems wrong.
