Start of a big DVB update. The reasons for revamping the DVB frontend architecture: Just as analog TV cards, DVB cards need some sort of tuner to tune to the desired frequency of the digital transponder. Tuning alone doesn't give you a digital DVB datastream, however, you need a demodulator as well. The combination of tuner and demodulator is called frontend in the DVB world. Tuner and demodulator are both accessed via the serial i2c bus on all DVB cards out there. So, technically a frontend consists of two i2c helper chipsets. In former times when there was only a handful of different DVB cards, the frontend was encapsulated in one tin box. Some people had the idea that there should be one "frontend driver" instead of dedicated tuner and demodulator drivers. A bad idea. As time went on, different manufacturers used the same tuner and demodulator combination, but used a different wiring for the tuner or did other technical changes. The only possibility to support different cards with one combined frontend driver was to add hardware dependent tuner code inside the generic i2c frontend drivers. Yuck. So there was a need for communication between the i2c frontend driver and the hardware depenedent driver, for example to exchange initialization code for the tuner. Unfortunately, the i2c infrastructure is one way, from the i2c client to the i2c adapter using a non-typesafe ioctl() like interface, which is ugly by itself. Greg K-H and others refused the idea to add an iotctl() like interface from the i2c adapter to the i2c client and instead proposed to use a typesafe interface instead. We all agreed with that. The existing i2c infrastructure heavily depends on the probing facility, ie. clients probe for their existence on i2c busses. This is dumb for most i2c busses out there that sit on dedicated hardware. A DVB card is uniquely identified with pci or usb subvendor and subsystem ids, so on that particular bus we exactly *know* which kinds of i2c helper chipsets sit on there. Up to now this wasn't a problem, because we could fix all conflicts manually until half a year ago. By that date, we found two different DVB designs which used different demodulators that unfortunately use the same i2c address and which cannot be distinguished by hardware tricks (ie. different number of registers, some fixed hw dependent register,...) Getting a usable DVB card depended on the load order of the modules, because the i2c core probed the demodulator drivers one after another and the first one won the race. Compiling all drivers statically into the kernel resulted in non-working cards. Our solution is as follows: we agreed to keep the basic underlying kernel i2c infrastructure, but we decided not to register our bussed and chipsets to the kernel i2c "probing" infrastructure. Instead, we killed the tuner parts of the frontend drivers and put them into the dedicated hardware drivers (this is were they technically belong, they are highly hardware dependent) and we changed the frontend drivers to pure demodulator drivers (which are hardware independend). There is now a type-safe functional dependency between the drivers and the demodulator drivers, the drivers explicitely ask the demodulator drivers to attach to their i2c bus. The only negative aspect of that approach is that for some hardware there are now more dependencies to demodulator drivers than needed, ie. a small amount of memory is wasted.

In 2.6.8 the code for the BLKRRPART ioctl was changed to return EIO when no partitions were found, such as on an empty disk. This breaks some partitioning programs and is also confusing: "Input/Output error" while in fact nothing was wrong with this brand new all blank disk. This restores old behaviour.

We recently found a problem that was causing memory corruption during boot on IBM POWER5 machines. The problem was that the if you have a USB keyboard and it is set to the input device for the firmware, it will still be active when the kernel is started. That means that the OHCI controller has pointers to various memory areas that it polls for transfers to do. When we start using that same memory in the kernel, bad things can happen. (This isn't a problem on powermacs because the Apple OF implements a "quiesce" call which turns off all the devices it is using.) This patch fixes the problem by calling the Open Firmware "close" method for the input device. Stephen Rothwell and I have verified that doing this fixes the problem on the POWER5 machine where we observed it. I verified that this patch doesn't cause any problems on powermacs. I think this patch should go into 2.6.10 since it fixes a nasty memory corruption bug that can cause rather subtle and hard-to-diagnose problems during boot. (The symptom on the POWER5 machine with the particular kernel that we were using was that reading /proc/net/tcp would oops, due to one of the pointers in tcp_ehash being corrupted.)

There's a chance that the receive buffers are being consumed at the same rate as they are being replenished in ibmveth_replenish_task()... Meanwhile, the calls to schedule_replenishing() from ibmveth_poll() won't schedule another replenishing cycle (because the not_replenishing flag is zero), starving the buffers and making the adapter unable to receive packets unless the module is reloaded... Here's a small patch that will fix it by scheduling another replenishing task after toggling the not_replenishing flag.

Patch from Marc Singer Add support for the LPD7a40x implementation of the SMC91x ethernet controller. This patch exists to work around a mismatch between the way the LH7a40x CPUs handle chip selects and what the ethernet controller expects. This patch has been revised to eliminate masking of interrupts. The concessions are that a) the ISR must perform an IOBARRIER before the first access to the chip, just in case the interrupt occurred while the driver was writing to the chip b) other drivers that use the same chip select region as the SMC chip must perform a similar IOBARRIER at the top of their ISRs.

Some time ago, a patch was merged that removed pci_save_state() and pci_restore_state() from various ALSA drivers. That patch also added pci_restore_state() to sound/core/init.c but didn't add pci_save_state() anywhere. This is needed since the core pci handling doesn't do this for us anymore. My laptop doesn't resume (gets what I assume is an ACPI timeout and hangs solid) without this small obvious patch.

We have to load the bigkernel second TLB entry on secondary processors before we move over the use the kernel trap table. Otherwise we can take a TLB miss somewhere in the post-4MB area and the TLB handler is not prepared to service that. The case that usually occurs is the prom_set_trap_table call made by trampoline.S, since p1275buf usually sits very near the end of the kernel image. It worked by luck most of the time as long as p1275buf sits within a single page since earlier code running in trampoline.S forced that TLB entry to be loaded by the OBP TLB miss handler. This was not fun to figure out. Signed-off-by: David S. Miller <davem@davemloft.net>
