There's no need for the GFX workaround now we have 'iommu=pt' for the
cases where people really care about performance. There's no need to
have a special case for just one type of device.
This also speeds up the iommu=pt path and reduces memory usage by
setting up the si_domain _once_ and then using it for all devices,
rather than giving each device its own private page tables.

While testing the driver on PPC, we ran into a crash with LRO, Jumbo frames.
With CONFIG_PPC_64K_PAGES configured (a default in PPC), MAX_SKB_FRAGS drops to 3 and we were crossing the array limits on skb_shinfo(skb)->frags[].
Now we coalesce the frags from the same physical page into one slot in
skb_shinfo(skb)->frags[] and go to the next index when the frag is from
different physical page.

Use BLOCK_NIL consistently rather than sometimes 0xffff and sometimes

The semantic patch that finds this issue is below
(http://www.emn.fr/x-info/coccinelle/). On the other hand, the changes
were made by hand, in part because drivers/mtd/inftlcore.c contains dead
code that causes spatch to ignore a relevant function. Specifically, the
function INFTL_findwriteunit contains a do-while loop, but always takes a
return that leaves the loop on the first iteration.

There are some devices in the wild that clear the DRQ bit during the
last word of a packet command and therefore could use a "second chance"
for that last word of data to be xferred instead of simply failing the

In addition, the ATA_ERR bit has to be cleared for we cannot be sure the

Alright, I've reworked this now so that if we get one of these cases
where there's a bsr that's > 4k and < 64k on a 64k kernel we'll only
advertise that it is a 4k BSR to userspace. I think this is the best
solution since user programs are only supposed to look at sysfs to
determine how much can be mapped, and libbsr does this as well.

looking for for supported devices. When we find an appropriate

then walk back down the PCI bus, assuming that every device

The eee contains a logically (but not physically) hotpluggable PCIe slot.
Currently this is handled by adding or removing the PCI device in response
to rfkill events, but if a user has forced pciehp to bind to it (with the
force=1 argument) then both drivers will try to handle the event and
hilarity (in the form of oopses) will ensue. This can be avoided by having
eee-laptop register the slot as a hotplug slot. Only one of pciehp and
eee-laptop will successfully register this, avoiding the problem.

the goto failed straight into ncr_detach() which oopses.
The fix is just to return -ENODEV in this case.

to free memory based on its stale value, and will free one too many
times. The result is that memory is freed back to the kernel while
its packet is still in the transmit buffer. If the memory is
overwritten before it is transmitted, the hardware will put a valid
checksum on it and send it out (just like it does with good packets).
If by chance the TCP flags are clobbered but not the addresses or
ports, the result can be a broken TCP stream.
The fix is to track the number of freed packets in a single location
(a Fetch-and-Add Unit register). That way it can never get out of sync
with itself.
We try to free up to MAX_SKB_TO_FREE (currently 10) buffers at a time.
If fewer are available we adjust the free count with the difference.
The action of claiming buffers to free is atomic so two threads cannot
claim the same buffers.

Identity mapping for IOMMU defines a single domain to 1:1 map all PCI
devices to all usable memory.
This reduces map/unmap overhead in DMA API's and improve IOMMU
performance. On 10Gb network cards, Netperf shows no performance
degradation compared to non-IOMMU performance.
This method may lose some of DMA remapping benefits like isolation.
The patch sets up identity mapping for all PCI devices to all usable
memory. In the DMA API, there is no overhead to maintain page tables,
invalidate iotlb, flush cache etc.
32 bit DMA devices don't use identity mapping domain, in order to access
memory beyond 4GiB.
When kernel option iommu=pt, pass through is first tried. If pass
through succeeds, IOMMU goes to pass through. If pass through is not
supported in hw or fail for whatever reason, IOMMU goes to identity
mapping.

There already is a "default-on" trigger but there are problems with it.
For one, it's a inefficient way to do it and requires led trigger support
to be compiled in.
But the real reason is that is produces a glitch on the LED. The GPIO is
allocate with the LED *off*, then *later* when the trigger runs it is
turned back on. If the LED was already on via the GPIO's reset default or
action of the firmware, this produces a glitch where the LED goes from on
to off to on. While normally this is fast enough that it wouldn't be
noticeable to a human observer, there are still serious problems.
One is that there may be something else on the GPIO line, like a hardware
alarm or watchdog, that is fast enough to notice the glitch.
Another is that the kernel may panic before the LED is turned back on, thus
hanging with the LED in the wrong state. This is not just speculation, but
actually happened to me with an embedded system that has an LED which
should turn off when the kernel finishes booting, which was left in the
incorrect state due to a bug in the OF LED binding code.
We also let GPIO LEDs get their initial value from whatever the current
state of the GPIO line is. On some systems the LEDs are put into some
state by the firmware or hardware before Linux boots, and it is desired to
have them keep this state which is otherwise unknown to Linux.
This requires that the underlying GPIO driver support reading the value of
output GPIOs. Some drivers support this and some do not.
The platform device binding gains a field in the platform data
"default_state" that controls this. There are three constants defined to
select from on, off, or keeping the current state. The OpenFirmware
binding uses a property named "default-state" that can be set to "on",
"off", or "keep". The default if the property isn't present is off.

- period: from 0s to 1.6s
- duty cycle: percentage of the period the led is on, from 0 to 100

In the TRY_FMT handler the function get_scale() is called to find what the
scaler hardware will produce for a requested size.
The problem is that get_scale(struct cx231xx *dev, ..., unsigned int *vscale,
unsigned int *hscale) saves the calculated scale values into both the
pointer arguments and into dev's hscale and vscale fields. TRY_FMT shouldn't
actually change anything in the device state.
The code to in get_scale() that writes to dev->[hv]scale can just be
deleted. In all cases when dev's fields should be modified, get_scale()
was called with get_scale(dev, ..., &dev->hscale, &dev->vscale), so dev was
getting updated anyway.
This didn't actually cause a problem because nothing ever actually made use
of the hscale and vscale fields. I changed cx231xx_resolution_set() to use
those fields rather than re-calculate them with a call to get_scale().
Updating [hv]scale in cx231xx_resolution_set() isn't necessary because
every call of cx231xx_resolution_set() was already preceded by a call to
get_scale() or setting the [hv]scale fields, so they will be always be
up-to-date w.r.t. width and height.
Removing the call to get_scale() from cx231xx_resolution_set() allowed
making get_scale() a static function, which is a good thing for something
with such a short name. There is already another function with the same
name in the em28xx driver, but that one is static.

The v4l function has a better algorithm for aligning image size.
It appears that the em2800 can only scale by 50% or 100%, i.e. the only
heights supported might be 240 and 480. In that case the old code would
set any height other than 240 to 480. Request 240 get 240, but request 239
and then you get 480. Change it to round to the nearest supported value.

Most hardware has limits on minimum and maximum image dimensions and also
requirements about alignment. For example, image width must be even or a
multiple of four. Some hardware has requirements that the total image size
(width * height) be a multiple of some power of two.
v4l_bound_align_image() will enforce min and max width and height, power of
two alignment on width and height, and power of two alignment on total
image size.
It uses an efficient algorithm that will try to find the "closest" image
size that meets the requirements.

The cx25840 module's VBI initialization logic uses the current video
standard as part of its internal algorithm. This therefore means that
we probably need to make sure that the correct video standard has been
set before initializing VBI. (Normally we would not care about VBI,
but as described in an earlier changeset, VBI must be initialized
correctly on the cx25840 in order for the chip's hardware scaler to
operate correctly.)
It's kind of messy to force the video standard to be set before
initializing VBI (mainly because we can't know what the app really
wants that early in the initialization process). So this patch does
the next best thing: VBI is re-initialized after any point where the
video standard has been set.
Signed-off-by: Mike Isely <isely@pobox.com>

The cx25840 module requires that its VBI initialization entry point be
called in order for hardware-scaled video capture to work properly -
even if we don't care about VBI. Making this behavior even more
subtle is that if the capture resolution is set to 720x480 - which is
the default that the pvrusb2 driver sets up - then the cx25840
bypasses the hardware scaler. Therefore this problem does not
manifest itself until some other resolution, e.g. 640x480, is tried.
MythTV typically defaults to 640x480 or 480x480, which means that
things break whenever the driver is used with MythTV.
This all has been known for a while (since at least Nov 2006), but
recent changes in the pvrusb2 driver (specifically in regards to
sub-device support) caused this to break again. VBI initialization
must happen *after* the chip's firmware is loaded, not before. With
this fix, 24xxx devices work correctly again.
A related fix that is part of this changeset is that now we
re-initialize VBI any time after we issue a reset to the cx25840
driver. Issuing a chip reset erases the state that the VBI setup
previously did. Until the HVR-1950 came along this subtlety went
unnoticed, because the pvrusb2 driver previously never issued such a
reset. But with the HVR-1950 we have to do that reset in order to
correctly transition from digital back to analog mode - and since the
HVR-1950 always starts in digital mode (required for the DVB side to
initialize correctly) then this device has never had a chance to work
correctly in analog mode! Analog capture on the HVR-1950 has been
broken this *ENTIRE* time. I had missed it until now because I've
usually been testing at the default 720x480 resolution which does not
require scaling... What fun. By re-initializing VBI after a cx25840
chip reset, correct behavior is restored.

In cases where the board had a default USB ID, we would not indentify the

boards the analog GPIOs were not being set before probing the i2c bus for
devices (the probe would occur with the GPIOs being all high).
Make a call to em28xx_set_mode() so that the GPIOs are set properly before

As reported on the ov51x-jpeg list, and as I can confirm with my own cam
the ov7670 in 320x240 has a number of broken columns of pixels
at the left of the picture. This was not present in the old
driver as it always used 640x480 and did software
downscaling (took me a while to figure that one out).
The fix adds a sensor specific if in so far sensor

The fix for the UV swapping in qcif mode with the ov6630, which I did
to fix this issue on a ov518 cam with an ov66308AF, causes UV swapping in

Implement toleration of dynamic memory operations and 16 GB gigantic
pages, where "toleration" means that the driver can cope with dynamic
memory operations that happen before the driver is loaded. While the
ehca driver is loaded, dynamic memory operations are still prohibited
by returning NOTIFY_BAD from the memory notifier.
On module load the driver walks through available system memory,
checks for available memory ranges and then registers the kernel
internal memory region accordingly. The translation of address ranges
is implemented via a 3-level busmap.

We need to save register state *after* idling GEM, clearing the ring,
and uninstalling the IRQ handler, or we might end up saving bogus
fence regs, for one. Our restore ordering should already be correct,
since we do GEM, ring and IRQ init after restoring the last register
state, which prevents us from clobbering things.

The ppp layer goes around calling the unthrottle method from non sleeping
paths. This isn't safe because the unthrottle methods in the tty layer need
to be able to sleep (consider a USB dongle).
Until now this didn't show up because the ppp layer never actually throttled
a port so the unthrottle was always a no-op. Currently it's a mutex taking
path so warnings are spewed if the unthrottle occurs via certain paths.
Fix this by removing the unneccessary unthrottle calls.

This patch changes postfix to prefix decrements in this and similar

parport_pc_probe_port() creates the own 'parport_pc' device if the
device argument is NULL. Then parport_pc_probe_port() doesn't
initialize the dma_mask and coherent_dma_mask of the device and calls
dma_alloc_coherent with it. dma_alloc_coherent fails because
dma_alloc_coherent() doesn't accept the uninitialized dma_mask:
http://lkml.org/lkml/2009/6/16/150
Long ago, X86_32 and X86_64 had the own dma_alloc_coherent
implementations; X86_32 accepted a device having dma_mask that is not
initialized however X86_64 didn't. When we merged them, we chose to
prohibit a device having dma_mask that is not initialized. I think
that it's good to require drivers to set up dma_mask (and
coherent_dma_mask) properly if the drivers want DMA.

To set a dasd online dasd_change_state is called twice. The first
cycle will schedule initial analysis of the device, set the rc to

The initial analysis will in turn call dasd_change_state to increase
the state to the final DASD_STATE_ONLINE.
If the dasd_change_state on the second thread outruns the other one
both finish with the state set to DASD_STATE_ONLINE and the device
refcount will be decreased by 2.
