A compiler barrier (explicit on the read side, implicit on the write
side) is not quite enough for what has to be accomplished here. Use
hardware memory barriers on systems which need them.
(Of course a full fix of generation handling would require much more
than this. The ieee1394 core's bus generation counter had to be tied to
the controller's bus generation counter; cf. Kristian's stack. It's
just that I have other current business with the code around these
barrier()s, so why not do at least this small fix.)

Combination of the following changes:
Tue, 26 Aug 2008 00:17:30 +0200 (CEST)
firedtv: fix remote control input
and update the scancode-to-keycode mapping to a current model. Per
default, various media key keycodes are emitted which closely match what
is printed on the remote. Userland can modify the mapping by means of
evdev ioctls. (Not tested.)
The old scancode-to-keycode mapping is left in the driver but cannot be
modified by ioctls. This preserves status quo for old remotes.

firedtv: replace tasklet by workqueue job
Non-atomic context is a lot nicer to work with.
Sun, 24 Aug 2008 23:30:00 +0200 (CEST)
firedtv: move some code back to ieee1394 core
Partially reverts "ieee1394: remove unused code" of Linux 2.6.25.
Sun, 24 Aug 2008 23:29:30 +0200 (CEST)
firedtv: replace semaphore by mutex
firesat->avc_sem and ->demux_sem have been used exactly like a mutex.
The only exception is the schedule_remotecontrol tasklet which did a
down_trylock in atomic context. This is not possible with
mutex_trylock; however the whole remote control related code is
non-functional anyway at the moment. This should be fixed eventually,
probably by turning the tasklet into a worqueue job.
Convert everything else from semaphore to mutex.
Also rewrite a few of the affected functions to unlock the mutex at a
single exit point, instead of in several branches.
Sun, 24 Aug 2008 23:28:45 +0200 (CEST)
firedtv: some header cleanups
Unify #ifndef/#define/#endif guards against multiple inclusion.
Drop extern keyword from function declarations.
Remove #include's into header files where struct declarations suffice.
Remove unused ohci1394 interface and related unused ieee1394 interfaces.
Add a few missing #include's and remove a few apparently obsolete ones.
Sort them alphabetically.

firedtv: nicer registration message and some initialization fixes
Print the correct name in dvb_register_adapter().
While we are at it, replace two switch cascades by one for loop, remove
a superfluous member of struct firesat and of two unused arguments of
AVCIdentifySubunit(), and fix bogus kfree's in firesat_dvbdev_init().
Tue, 26 Aug 2008 14:24:17 +0200 (CEST)
firesat: rename to firedtv
Suggested by Andreas Monitzer. Besides DVB-S/-S2 receivers, the driver
also supports DVB-C and DVB-T receivers, hence the previous project name
is too narrow now.
Not yet done: Rename source directory, files, types, variables...

I have finally managed to get the CI support for the card working. The
implementation is a bare minimum to get encrypted channels to work in
kaffeine. It works fine with my T/CI card. Now and then I get an AVC
timeout and have to retune a channel in order to get it to work. Once
the CAM seemed to hang so I needed to remove and insert it again. I.e.
there are a number of glitches.
The latest version contains the following changes:
- Implemented the new hpsb iso interface so that data can be received
from the card
- Reduced some timers for demux setup which caused scanning to timeout
- Added possibility to unload driver
- Added support for getting C/N ratio
- Added two debug parameters to the driver; ca_debug and
avc_comm_debug.
- Added CI support that works for me in kaffeine
- Started working on CI MMI support. It now supports:
o Enter menu
o Receiving MMI objects
- Added support for 64-bit platforms
- Corrected DVB-C modulations problems

This only makes sure that a DVB-S2 device is really recognized as a S2,
nothing else is added yet. It's using the string containing the model
that is stored in the configuration ROM, the older version was using
some hardware revision dependent part of the ROM.

net: amend the fix for SO_BSDCOMPAT gsopt infoleak
netns: build fix for net_alloc_generic
de_get is called before every proc_get_inode, but corresponding de_put is
called only when dropping last reference to an inode. This might cause
something like
remove_proc_entry: /proc/stats busy, count=14496
to be printed to the syslog.
The fix is to call de_put in case of an already initialized inode in
proc_get_inode.

The fix for CVE-2009-0676 (upstream commit df0bca04) is incomplete. Note
that the same problem of leaking kernel memory will reappear if someone
on some architecture uses struct timeval with some internal padding (for
example tv_sec 64-bit and tv_usec 32-bit) --- then, you are going to
leak the padded bytes to userspace.

The problem was that object_set_to_gpu_domain would set the new write_domains
that are getting set by this batchbuffer, then the accumulated flushes required
for all the objects in preparation for this batchbuffer were posted, and the
brand new write domain would get cleared by the flush being posted. Instead,
hang on to the new (or old if we're not changing it) value and set it after
the flush is queued.
Results from this noticably included conformance test failures from reads
shortly after writes (where the new write domain had been lost and thus not
flushed and waited on), but is a suspected cause of hangs in some apps when
a write domain is lost on a buffer that gets reused for instruction or
commmand state.
