[PATCH] Update cyblafb driver
This is a major update to the cyblafb framebuffer driver. Most
of the stuff has been tested in the mm tree.
Main advantages:
============
- vxres > xres support
- ywrap and xpan support
- much faster for almost all modes (e.g. 1280x1024-16bpp
draws more than 41 full screens of text instead of about 25
full screens of text per second on authors Epia 5000)
- module init/exit code fixed
- bugs triggered by console rotation fixed
- lots of minor improvements
- startup modes suitable for high performance scrolling
in all directions
This diff also contains a lot of white space fixes.
No side effects are possible, only one single graphics core is affected.

[PATCH] sata_nv, spurious interrupts at system startup with MAXTOR 6H500F0 drive
This patch works around a problem with spurious interrupts seen at boot time when
a MAXTOR 6H500F0 drive is present. An ATA interrupt condition is mysteriously
present at start of day. If we took too long in issuing the first command,
the kernel would basically get tired of the spurious interrupts and turn the interrupt
off. Issuing the first command essentially causes the interrupt condition to
get acknowledged.
I haven't seen this happen with any other drives.
What I basically do is ack ATA status by reading it regardless of whether we're
expecting to have to handle an interrupt. This clears the start-of-day anomalous
interrupt condition, and keeps the kernel from disabling that interrupt due to
too many spurious interrupts.
Also, I fixed a bug where hotplug interrupts weren't getting acknowledged as handled
in the ISR. This was not the cause of the spurious interrupts, but it's the right
thing to do anyway.

This is the platform function interpreter itself along with the backends
for UniN/U3/U4, mac-io, GPIOs and i2c. It adds the ability to execute
those do-platform-* scripts in the device-tree (at least for most
devices for which a backend is provided). This should replace the clock
spreading hacks properly. It might also have an impact on all sort of
machines since some of the scripts marked "at init" will now be executed
on boot (or some other on sleep/wakeup), those will possibly do things
that the kernel didn't do at all, like setting some values into some i2c
devices (changing thermal sensor calibration or conversion rate) etc...
Thus regression testing is MUCH welcome. Also loook for errors in dmesg.
That's also why I've left rather verbose debugging enabled in this
version of the patch.
(I do expect some Windtunnel G4s to show some errors as they have an i2c
clock chip on the PMU bus that uses some primitives that the i2c backend
doesn't implement yet. I really need users that have one of those
machine to come back to me so we can get that done right, though the

devices. Compatibility with existing drivers should be maintained as the
i2c bus names have been kept identical, except for the SMU bus but in
