V4L/DVB: vivi: fix depends again

My previous patch to depend on FONTS was not sufficient since
FONTS is boolean.  VIDEO_VIVI needs to depend on a tristate so that
it won't be enabled as =y when framebuffer is built as modular, so
modify it to depend on the same symbols that FONTS depends on, which
are FRAMEBUFFER_CONSOLE || STI_CONSOLE.

Fixes this build error when VIDEO_VIVI=y and FRAMEBUFFER_CONSOLE=m:
vivi.c:(.init.text+0x7205): undefined reference to `find_font'

V4L/DVB: ir-core: move decoding state to ir_raw_event_ctrl

This patch moves the state from each raw decoder into the
ir_raw_event_ctrl struct.

This allows the removal of code like this:

        spin_lock(&decoder_lock);
        list_for_each_entry(data, &decoder_list, list) {
                if (data->ir_dev == ir_dev)
                        break;
        }
        spin_unlock(&decoder_lock);
        return data;

which is currently run for each decoder on each event in order
to get the client-specific decoding state data.

In addition, ir decoding modules and ir driver module load
order is now independent. Centralizing the data also allows
for a nice code reduction of about 30% per raw decoder as
client lists and client registration callbacks are no longer
necessary (but still kept around for the benefit of the lirc
decoder).

Out-of-tree modules can still use a similar trick to what
the raw decoders did before this patch until they are merged.

V4L/DVB: ir-core: centralize sysfs raw decoder enabling/disabling

With the current logic, each raw decoder needs to add a copy of the exact
same sysfs code. This is both unnecessary and also means that (re)loading
an IR driver after raw decoder modules have been loaded won't work as
expected.

This patch moves that logic into ir-raw-event and adds a single sysfs
file per device.

Reading that file returns something like:

"rc5 [rc6] nec jvc [sony]"

(with enabled protocols in [] brackets)

Writing either "+protocol" or "-protocol" to that file will
enable or disable the according protocol decoder.

An additional benefit is that the disabling of a decoder will be
remembered across module removal/insertion so a previously
disabled decoder won't suddenly be activated again. The default
setting is to enable all decoders.

This is also necessary for the next patch which moves even more decoder
state into the central raw decoding structs.

V4L/DVB: Fix case where fields were not at the correct start location

This patch address an arithmetic error for the case where the only remaining
content in the USB packet was the "225Axxxx" start of active video.  In cases
where that happened to be at the end of the frame, we would inject it into the
videobuf (which is incorrect).  This caused fields to be intermittently
rendered off by two pixels.

Thanks to Eugeniy Meshcheryakov for bringing this issue to my attention

V4L/DVB: ivtv: Add firmare monitoring and debug mode to ignore firmware problems

>From Ian's e-mail:
When a device is opened the firmware state will be checked. If it isn't
responding then the open will fail with -EIO.  Due to the nature of the
hardware, a single failed check will block everything since we don't know
exactly what has failed. A side effect of this is the blocking of debug
access, so an additional debug level has been created which allows the block
to be bypassed.

Andy Walls' modifications:
I modified Ian's patch to add a separate fw_debug module parameter to change
the driver's behavior, as opposed to using the normal debug module parameter.
The fw_debug module parameter is only available when CONFIG_VIDEO_ADV_DEBUG
is set.
I also made some minor whitespace adjustments and changed some warning
messages to be a bit more specific.  s/happy/glad/g

Jarod Wilson [Sun, 7 Mar 2010 20:20:03 +0000 (17:20 -0300)]
V4L/DVB: dvb: add lgdt3304 support to lgdt3305 driver

There's a currently-unused lgdt3304 demod driver, which leaves a lot to
be desired as far as functionality. The 3304 is unsurprisingly quite
similar to the 3305, and empirical testing yeilds far better results
and more complete functionality by merging 3304 support into the 3305
driver. (For example, the current lgdt3304 driver lacks support for
signal strength, snr, ucblocks, etc., which we get w/the lgdt3305).

For the moment, not dropping the lgdt3304 driver, and its still up to
a given device's config setup to choose which demod driver to use, but
I'd suggest dropping the 3304 driver entirely.

As a follow-up to this patch, I've got another patch that adds support
for the KWorld PlusTV 340U (ATSC) em2870-based tuner stick, driving
its lgdt3304 demod via this lgdt3305 driver, which is what I used to
successfully test this patch with both VSB_8 and QAM_256 signals.

A few pieces are still a touch crude, but I think its a solid start,
as well as much cleaner and more feature-complete than the existing
lgdt3304 driver.

Self-NAK. The only place we actually *care* about the retval from a
RUN_DECODER() call is in __ir_input_register(), and currently, its
looking for retval < 0, which is currently never possible. When we're
running the decoders, either they fail and return -EINVAL or they
succeed and return 0, and in the register case, we get either a
negative error (ex: -ENOMEM from rc6) or 0, so with the above, _sumrc
will *always* be 0 in the two cases I'm looking at. The third place
where RUN_DECODER gets called (decoder unregister) doesn't care about
the retval either. New patch below, including updated comments about
the macro.

mm: fix ia64 crash when gcore reads gate area

Debian's ia64 autobuilders have been seeing kernel freeze or reboot
when running the gdb testsuite (Debian bug 588574): dannf bisected to
2.6.32 62eede62dafb4a6633eae7ffbeb34c60dba5e7b1 "mm: ZERO_PAGE without
PTE_SPECIAL"; and reproduced it with gdb's gcore on a simple target.

I'd missed updating the gate_vma handling in __get_user_pages(): that
happens to use vm_normal_page() (nowadays failing on the zero page),
yet reported success even when it failed to get a page - boom when
access_process_vm() tried to copy that to its intermediate buffer.

Fix this, resisting cleanups: in particular, leave it for now reporting
success when not asked to get any pages - very probably safe to change,
but let's not risk it without testing exposure.

Why did ia64 crash with 16kB pages, but succeed with 64kB pages?
Because setup_gate() pads each 64kB of its gate area with zero pages.
