Content for the 8bit device threaded interrupt handlers. Depending on the
interrupt line and chip configuration, either click or wakeup / freefall
handler is called. In case of click, BTN_ event is sent via input device.
In case of wakeup or freefall, input device ABS_ events are updated
immediatelly.
It is still possible to configure interrupt line 1 for fast freefall
detection and use the second line either for click or threshold based
interrupts. Or both lines can be used for click / threshold interrupts.
Polled input device can be set to stopped state and still get coordinate
updates via input device using interrupt based method. Polled mode and
interrupt mode can also be used parallel.
BTN_ events are remapped based on existing axis remapping information.

8 bit device has two wakeup / free fall units. It was not possible to
configure the second unit. This patch introduces configuration entry to
the platform data and also corresponding changes to the 8 bit setup
function.
High pass filters were enabled by default. Patch introduces configuration
option for high pass filter cut off frequency and also possibility to
disable or enable the filter via platform data. Since the control is a
new one and default state was filter enabled, new option is used to
disable the filter. This way old platform data is still compatible with
the change.

This changes the default of the option --git-all-signature-types to be
disabled by default.
The effect being, that only certain (currently Signed-Off-By:, Acked-by:
and Reviewed-By:) tags are used to get adresses of potential maintainers.
Motivated is this change by the desire to not 'spam' people unnecessary: A
Tested-By or a Reported-By is not ment as a hint that those people want
to/are able to review patches to the code in question.
In a quest to find resilient statistics for this i came up with this:
I produced a list of all the tag-signers not already covered with a
signed-off/acked/reviewed tag somewhere in the last year of git history.
Those were 650 addresses of "assumed non-developers".
And to check if those "assumed non-developers" are professional
testers/reporters worth cc'ing, i then counted their total appearences
in the git log:
469 were mentioned only once.
123 were mentioned twice.
38 three times
8 four times
5 six times
5 five times
1 eight times
1 fourteen times
I believe this supports my thesis, that the ''non-maintainer-tags'' are
not actively useful for patch-review. (except probably the guy mentioned
fourteen times...)
But of course one could also find arguments to poke holes in this
statistics, for example does this statistic not include code-locality: A
tested-by on a patch that touches some specific piece of code can be more
worth than a signed-off in another part of the tree.
But... let's play it safe and let's err on the "safe" side meaning to not
spam those people when in doubt. We already have the signed-off's and
Maintainers file. So this should be ok. And if need be, the maintainers
can always forward the patch.

When using --git to determine who to send a patch to, get_maintainers will
currently include all signatures. This can include signers that simply
report an issue or test a patch. Signers that use this tag are not
necessarily good candidates to review new patches.
This patch allows get_maintainers to optionally restrict output to only
signatures that use Signed-off-by:, Acked-by:, or Reviewed-by:.
Signed-off-by: is included because those are people who are responsible
for the code.
Acked-by: is questionable, but as signers that use this tag tend to be
active linux gatekeepers, false positives are tolerable.
Reviewed-by: is included because signers responsible for the code thought
that the review feedback for a changeset by that signer was valuable.
This patch has been modified from Florian's original submission to change
the supported signature types to the canonical forms and use slightly
different spacing. A couple of spacing issues were also corrected in the
original source. The command line argument was also renamed.

This was corrected with linux 2.6.3 when Keith M Wesolowski changed the
implementation to use the parisc approach of having an array of spinlocks
to protect the atomic_t.
These warnings were also removed from the sparc implementation when the
new implementation was merged in BKrev:402e4949VThdc6D3iaosSFUgabMfvw, but
the warning still remained in some other places without any 24-bit-only
atomic_t implementation inside the kernel.
We should remove these warnings to allow users to rely on the full 32-bit
