c1db53b366 V4L/DVB: dvb: l64781.ko broken with gcc 4.5
I'm trying to fix it on the GCC side (PR43007), but the module is
quite stupid in using ULL constants to operate on u32 values:

static int apply_frontend_param (struct dvb_frontend* fe, struct
dvb_frontend_parameters *param)
{
...
 static const u32 ppm = 8000;
 u32 spi_bias;
...

 spi_bias *= 1000ULL;
 spi_bias /= 1000ULL + ppm/1000;

which causes current GCC 4.5 to emit calls to __udivdi3 for i?86 again.

This patch fixes this issue.

084e24acc9 V4L/DVB (12440): Use kzalloc for frontend states to have struct dvb_frontend properly
This patch changes most frontend drivers to allocate their state structure via
kzalloc and not kmalloc. This is done to properly initialize the
embedded "struct dvb_frontend frontend" field, that they all have.

The visible effect of this struct being uninitalized is, that the member "id"
that is used to set the name of kernel thread is totally random.

Some board drivers (for example cx88-dvb) set this "id" via
videobuf_dvb_alloc_frontend but most do not.

So I at least get random id values for saa7134, flexcop and ttpci based cards.
It looks like this in dmesg:
DVB: registering adapter 1 frontend -10551321 (ST STV0299 DVB-S)

The related kernel thread then also gets a strange name
like "kdvb-ad-1-fe--1".

dea74869f3 V4L/DVB (4028): Change dvb_frontend_ops to be a real field instead of a pointer field inside dvb_frontend
The dvb_frontend_ops is a pointer inside dvb_frontend. That's why every demod-driver
is having a field of dvb_frontend_ops in its private-state-struct and
using the reference for filling the pointer-field in dvb_frontend.
- It saves at least two lines of code per demod-driver,
- reduces object size (one less dereference per frontend_ops-access),
- be coherent with dvb_tuner_ops,
- makes it a little bit easier for newbies to understand how it works and
- avoids stupid mistakes because you would have to copy the dvb_frontend_ops
  always, before you could assign the static pointer directly, which was
  dangerous.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
