The raid autodetect code really needs to have all devices probed before
it can detect raid arrays; not doing so would give rather messy situations
where arrays would get detected as degraded while they shouldn't be etc.
This is in preparation of removing the "wait for everything to init"
code that makes everyone pay, not just raid users.

David Sanders reported some issues with bootgraph.pl's display
of his sytems bootup; this commit fixes these by scaling the graph
not from 0 - end time but from the first initcall to the end time;
the minimum display size etc also now need to scale with this, as does
the axis display.

When optimizing the kernel boot time, it's very valuable to visualize
what is going on at which time. In addition, with some of the initializing
going asynchronous soon, it's valuable to track/print which worker thread
is executing the initialization.
This patch adds a script to turn a dmesg into a SVG graph (that can be
shown with tools such as InkScape, Gimp or Firefox) and a small change
to the initcall code to print the PID of the thread calling the initcall
(so that the script can work out the parallelism).

Well, one thing you encouraged me to do was re-test some of my cards
which contained the xc3028-zarlink combo.
Which led me to test a Dvico FusionHDTV Pro.
Almost a year ago, Chris Pascoe did a patch for this which can be found
at his ~pascoe/xc-test at Linuxtv.
This worked very well, however that was using his version of firmware.
Alas, someone attempted to use this and patch v4l-dvb, and messed it up.
So I've fixed it.
I enclose the patch against today's tree (containing your latest
tuner-xc2028.c patch).
The card now works very well, well with DVB-T anyway.

The v4l core creates four different video devices (video, vbi, radio, vtx)
and each has its own range of minor numbers. However, modern devices keep
increasing the number of devices that they need so a maximum of 64 video
devices will not be enough in the future. In addition this scheme makes
it very hard to add new device types.
This patch disconnects the kernel number allocation (e.g. video0, video1,
etc.) from the actual minor number (just pick the first free minor).
This allows for much more flexibility in the future. However, it does
require the use of udev. For those who cannot use udev a new CONFIG option
was created that changes the allocation scheme back to the old behavior.
Thanks to Greg KH for suggesting this approach during the 2008 LPC.
In addition, several bugs were fixed in the ivtv and cx18 drivers: these
drivers try to allocate specific kernel numbers but that scheme contained
a bug which caused what should have been e.g. video17 to appear as e.g.
video2.

change implements MMIO retries and the retry_mmio module parameter that is

the mmio_ndelay parameter. mmio_ndelay has insignificant effect with retries
