This flag enables gcc to "see" the entire C file before making optimisation
decisions such as inline, which results in gcc making better decisions. One
of the immediate effects of this is that static functions that are used only
once now get inlined.
gcc 3.4 has this flag as well, however gcc 3.x have a problem with inlining
and stacks and as a result, enabling this flag there would cause excessive and

[PATCH] gx1fb: (try to) play nicer with various BIOSes
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
there -- probably best to get some more testers before applying it.

[PATCH] neofb: take existing display configuration as default
On a Dell Latitude CPi-A I noticed a strangeness wrt. the handling of an
external monitor by the neomagic framebuffer driver, namely when the laptop is
docked in a C/Dock II with the lid shut.
A cold boot would result in the BIOS configuring the video chip to use the
"external monitor only" mode, yet neofb would default to "internal LCD only".
An attempt for a quick fix by using the Fn-F8 keystroke to toggle the display
combination modes resulted in a reproductible hard lock, powering down being
the only solution.
The attached patch makes neofb probe the register for the current display
mode, using that value as a default if nothing was specified as kernel/module
parameter.

[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.

[PATCH] cpuset oom lock fix
The problem, reported in:
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

[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.

the goal of shrinking it by 30kb to 40kb

[PATCH] sched: add new SCHED_BATCH policy
Add a new SCHED_BATCH (3) scheduling policy: such tasks are presumed
CPU-intensive, and will acquire a constant +5 priority level penalty. Such
policy is nice for workloads that are non-interactive, but which do not
want to give up their nice levels. The policy is also useful for workloads
that want a deterministic scheduling policy without interactivity causing
extra preemptions (between that workload's tasks).

[PATCH] Altix: ioc3 serial support
Add driver support for a 2 port PCI IOC3-based serial card on Altix boxes:
This is a re-submission. On the original submission I was asked to
organize the code so that the MIPS ioc3 ethernet and serial parts could be
used with this driver. Stanislaw Skowronek was kind enough to provide the
shim layer for this - thanks Stanislaw. This patch includes the shim layer
and the Altix PCI ioc3 serial driver. The MIPS merged ioc3 ethernet and
serial support is forthcoming.

[PATCH] convert /proc/devices to use seq_file interface
A Christoph suggested that the /proc/devices file be converted to use the
seq_file interface. This patch does that.
I've obxerved one or two installation that had sufficiently large sans that
they overran the 4k limit on /proc/devices.
