While Module_Vendor_ID in the configuration ROM's root directory is
mandatory, there often aren't vendor IDs in unit directories. This
affects the new firedtv driver which is meant to be auto-loaded and
matched only for vendor-specific devices.
We now always copy ne->vendor_id into ud->vendor_id before we scan a
unit directory (and fill in a possibly present vendor ID from there).
This way, the root directory's vendor ID is used as fallback in the
"uevent" environment for modprobe'ing per module alias when a node was
plugged in, and in the driver match routine when protocol drivers are
bound to unit directories. It will however not be used as sysfs
attribute of a unit directory device.

These will be used by the firedtv driver. Like hpsb_node_write() they
are much better APIs for high-level drivers than hpsb_write() and its
siblings --- easier to use correctly and also terser.
Unlike hspb_node_write(), the two new functions will only be used by
one call site. Hence make them static inline instead of exported
symbols.

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.

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

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.

Impact: Cleanup
Checkin be44d2aabce2d62f72d5751d1871b6212bf7a1c7 eliminates the use of
a 16-bit stack for espfix. However, at least one instruction remained
that only operated on the low 16 bits of %esp.
This is not a bug per se because the kernel stack is always an aligned
4K or 8K block. Therefore it cannot cross 64K boundaries; this code,
in fact, relies strictly on that fact.
However, it's a lot cleaner (and, for that matter, smaller) to operate
on the entire 32-bit register.

Impact: fix early crash on LinuxBIOS systems
Kevin O'Connor reported that Coreboot aka LinuxBIOS tries to put
mptable somewhere very high, well above max_low_pfn (below which
BIOSes generally put the mptable), causing a panic.
The BIOS will probably be changed to be compatible with older
Linus versions, but nevertheless the MP-spec does not forbid
an MP-table in arbitrary system RAM, so make sure it all
works even if the table is in an unexpected place.
Check physptr with max_low_pfn * PAGE_SIZE.

Audiowerk2 driver snd-aw2 is bound to any saa7146 device as it does not
check subsystem ids. Many DVB devices are saa7146 based, so aw2 driver
grabs them as well.
According to http://lkml.org/lkml/2008/10/15/311 aw2 devices have the
subsystem ids set to 0, the saa7146 default.

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.

Impact: remove unused/broken code
The Voyager subarch last built successfully on the v2.6.26 kernel
and has been stale since then and does not build on the v2.6.27,
v2.6.28 and v2.6.29-rc5 kernels.
No actual users beyond the maintainer reported this breakage.
Patches were sent and most of the fixes were accepted but the
discussion around how to do a few remaining issues cleanly
fizzled out with no resolution and the code remained broken.
In the v2.6.30 x86 tree development cycle 32-bit subarch support
has been reworked and removed - and the Voyager code, beyond the
build problems already known, needs serious and significant
changes and probably a rewrite to support it.
CONFIG_X86_VOYAGER has been marked BROKEN then. The maintainer has
been notified but no patches have been sent so far to fix it.
While all other subarchs have been converted to the new scheme,
voyager is still broken. We'd prefer to receive patches which
clean up the current situation in a constructive way, but even in
case of removal there is no obstacle to add that support back
after the issues have been sorted out in a mutually acceptable
fashion.
So remove this inactive code for now.

At some point we (okay, I) managed to break the ability for users to use the
setsockopt() syscall to set IPv4 options when NetLabel was not active on the
socket in question. The problem was noticed by someone trying to use the
"-R" (record route) option of ping:
# ping -R 10.0.0.1
ping: record route: No message of desired type
The solution is relatively simple, we catch the unlabeled socket case and
clear the error code, allowing the operation to succeed. Please note that we
still deny users the ability to override IPv4 options on socket's which have
NetLabel labeling active; this is done to ensure the labeling remains intact.

The kernel-api docbook was much larger than any of the others,
so processing it took longer and needed some docbook extras in
some cases, so split it into kernel-api (infrastructure etc.)
and device drivers/device subsystems. This allows these docbooks
to be generated in parallel. (This reduced the docbook processing
time on my 4-proc system with make -j4 from about 5min:16sec to
about 2min:01sec.)
The chapters that were moved from kernel-api to device-drivers are:
Driver Basics

Right now nobody cares, but the suspend/resume code will eventually want
to suspend device interrupts without suspending the timer, and will
depend on this flag to know.
The modern x86 timer infrastructure uses the local APIC timers and never
shows up as a device interrupt at all, so it isn't affected and doesn't
need any of this.
