The offset field of the scatterlist entry *after* the last valid scatterlist
entry was used instead of the first scatterlist entry (as was the intention
of this code).
This worked fine until the kzalloc of the sglist was replaced with kmalloc
and sg_init_table only zeroed the exact needed length. Apparently kzalloc
zeroes a bit more than is strictly necessary so the offset field was
always 0 in the past.
But now the offset field was suddenly random and this led to broken captures.

with this config:
http://redhat.com/~mingo/misc/config-Tue_May_20_18_11_34_CEST_2008.bad
the reason is another kconfig tool bug that has to be worked around in
the driver's Kconfig file: if FW_LOADER is selected in a second
dependency, that is not properly propagated up the dependencies.
in this case, FW_LOADER is selected from MEDIA_TUNER_XC2028:
config MEDIA_TUNER_XC2028
tristate "XCeive xc2028/xc3028 tuners"
depends on VIDEO_MEDIA && I2C
depends on HOTPLUG
select FW_LOADER
which got selected by MEDIA_TUNER:
config MEDIA_TUNER
tristate
default VIDEO_MEDIA && I2C
depends on VIDEO_MEDIA && I2C
select FW_LOADER if !MEDIA_TUNER_CUSTOMIZE && HOTPLUG
but the kconfig tool did not pick up this second-order dependency and
allowed CONFIG_FW_LOADER=m to be selected - in which case the build
fails.
the workaround i found was to move the select of FW_LOADER one level up,
so that the buggy kconfig tool can notice it and can act appropriately.
This problem can probably be worked around in other ways as well, i went
for the minimal fix.
Obviously, the kconfig tool should be fixed, it is not reasonable to
expect driver authors to do manual dependency resolution (that kconfig
itself already does) and uglify the Kconfig files. The kconfig tool did
nothing to warn about this situation and did not prevent this faulty
.config from being constructed.

The current code passes a context pointer in the xc5000_config struct.
This context pointer is used in the tuner_callback function, used to
reset the device after firmware download.
The xc5000_config struct is a static structure, whose .priv member was
being assigned before calling xc5000_attach(). If there are more than
one of the same device type installed on a single system, the last one
to assign xc5000_config.priv will "win", and all others will cease to
function properly.
This patch passes the context pointer in xc5000_attach() rather that
storing it within the static struct xc5000_config.

Since:
1) FW_LOADER is defined as:
config FW_LOADER
tristate "Userspace firmware loading support"
depends on HOTPLUG
2) several V4L/DVB driver just selects it;
3) select is not smart enough to auto-select HOTPLUG, if select FW_LOADER.
So, All drivers that select FW_LOADER should also depend on HOTPLUG.
An easier solution (for the end-user perspective) would be to "select HOTPLUG".
However, live is not simple. This would cause recursive dependency issues like
this one:

As pointed by Adrian Bunk, with I2C=m and VIDEO_DEV=y, videodev brokes.
This patch moves the functions that videodev needs from v4l2-common. It also
fixes some Kconfig changes.
After this patch, I2C=m / VIDEO_DEV=y will make v4l2 core statically linked
into kernel. v4l2-common will be m, and all V4L drivers will also be m.
This approach is very conservative, since it is possible to have V4L drivers
that don't need I2C or v4l2-common. The better is to map what drivers really
need v4l2-common, making them to select v4l2-common, and allowing the others to
be 'y', 'm' and 'n'.

The ttpci Kconfig file has bugs that cause it to fail in certain Kconfig
situations. The basic problem is that it selects certain drivers, but does
not depend on the dependencies of those drivers.
See http://article.gmane.org/gmane.comp.video.video4linux/35072
Using the Kconfig file also has some annoyances. For instance one can't turn
off AV7110 support unless you go down several options and first turn off
budget-patch support. Normally user selectable drivers are not forced on like
this.
The "AV7110 cards with Budget Patch" option is disabled if "Budget cards"
isn't on. Normally a driver appears nested under a driver it depends on, but
since drivers that don't depend on "Budget cards" are between the two options,
the config programs can't display the tree correctly.
The Makefile has an issue too. Some modules, ttpci-eeprom and budget-core,
appear in the Makefile under several different config symbols. If more than
one of these symbols is on, they will get added the to list of objects
multiple times. The normal convention is to have a config symbol just the
common object(s) and have the users of the that object either depend on or
select that config symbol.
This patch fixes all these issues. ttpci-eepom is under a new config symbol,
and so is the budget-core module. The four different budget card types appear
as sub-drivers under a main "SAA7146 DVB cards" option. Turning on
budget-patch doesn't force AV7110. Drivers using SAA7146_VV have the
necessary VIDEO_DEV dependency, so that it isn't possible to select SAA7146_VV
without V4L being on.

Given that the author used an ß at all in a source file
indicates that the real name has in fact a 'ß' and not an 'ss',

PCI-dependent videobuf_foo methods were renamed as videobuf_pci_foo.
Also, videobuf_dmabuf is now part of videobuf-dma-sg private struct.
So, to access it, a subroutine call is needed.
This patch renames all occurences of those function calls to be
consistent with the video-buf split.

I added saa7146_vmalloc_destroy_pgtable() which frees the resources
allocated by saa7146_vmalloc_build_pgtable() and updated the callers in
budget-core.c and av7110.c. I have also been through the updated
functions and updated the error paths to ensure they free all allocated
resources on error.
I also realised that there are other callers to saa7146_pgtable_free()
which did not have any sg DMA mapped so it seems wrong to add the
pci_unmap_sg() into that function. Instead I created
saa7146_vmalloc_destroy_pgtable() to do this.
Also included in this patch are the previous fixes for pci_unmap_sg()
and syncing the PCI streamed data to work with a SWIOTLB and match the
requirements documented in DMA-API.txt.

This converts the budget-ci driver so that it uses ir-common for some of its
IR processing. In particular, the keymap for the Nova-T (sub 13c2:1011) is
switched to the Hauppauge grey/black keymap, of which the keys on the
supplied R808 remote control form a subset.
The old budget-ci keymap is moved to ir-keymaps.c and is used for other
remotes.
The debounce logic for buggy remotes (i.e. Zenith) is made conditional the
new debounce parameter and defaults to off (so that repeat keypresses aren't
ignored for all working remotes).
Some parts are based on Darren Salt's dvb-ir patchset.

Maintain a per-CPU global "struct pt_regs *" variable which can be used instead
of passing regs around manually through all ~1800 interrupt handlers in the
Linux kernel.
The regs pointer is used in few places, but it potentially costs both stack
space and code to pass it around. On the FRV arch, removing the regs parameter
from all the genirq function results in a 20% speed up of the IRQ exit path
(ie: from leaving timer_interrupt() to leaving do_IRQ()).
Where appropriate, an arch may override the generic storage facility and do
something different with the variable. On FRV, for instance, the address is
maintained in GR28 at all times inside the kernel as part of general exception
handling.
Having looked over the code, it appears that the parameter may be handed down
through up to twenty or so layers of functions. Consider a USB character
device attached to a USB hub, attached to a USB controller that posts its
interrupts through a cascaded auxiliary interrupt controller. A character
device driver may want to pass regs to the sysrq handler through the input
layer which adds another few layers of parameter passing.
I've build this code with allyesconfig for x86_64 and i386. I've runtested the
main part of the code on FRV and i386, though I can't test most of the drivers.
I've also done partial conversion for powerpc and MIPS - these at least compile
with minimal configurations.
This will affect all archs. Mostly the changes should be relatively easy.
Take do_IRQ(), store the regs pointer at the beginning, saving the old one:
struct pt_regs *old_regs = set_irq_regs(regs);
And put the old one back at the end:
set_irq_regs(old_regs);
Don't pass regs through to generic_handle_irq() or __do_IRQ().
In timer_interrupt(), this sort of change will be necessary:
- update_process_times(user_mode(regs));
- profile_tick(CPU_PROFILING, regs);
+ update_process_times(user_mode(get_irq_regs()));
+ profile_tick(CPU_PROFILING);
I'd like to move update_process_times()'s use of get_irq_regs() into itself,
except that i386, alone of the archs, uses something other than user_mode().
Some notes on the interrupt handling in the drivers:
(*) input_dev() is now gone entirely. The regs pointer is no longer stored in
the input_dev struct.
(*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does
something different depending on whether it's been supplied with a regs
pointer or not.
(*) Various IRQ handler function pointers have been moved to type
irq_handler_t.
