After GPU lockup VRAM gart table is unpinned and thus its pointer
becomes unvalid. This patch move the unpin code to a common helper
function and set pointer to NULL so that page update code can check
if it should update GPU page table or not. That way bo still bound
to GART can be unbound (pci_unmap_page for all there page) properly
while there is no need to update the GPU page table.
V2 move the test for null gart out of the loop, small optimization

Polarity needs to be set accordingly to connector status (connected
or disconnected). Set it up in hpd_init() so first hotplug works
reliably no matter what is the initial set of connector. hpd_init()
also covers resume so HPD will work correctly after resume as well.

Allow the user to override whether MSIs are enabled
or not on supported ASICs. MSIs are disabled by default
on IGP chips as they tend not to work. However certain
IGP chips only seem to work with MSIs enabled.
I suspect this is a chipset or bios issue, but I'm not sure
what the proper fix is. This will at least make diagnosing
and working around the problem much easier.

We need to redefine a connector as "connected" if it matches a window
in the host preferred GUI layout.
Otherwise "smart" window managers would turn on Xorg outputs that we don't
want to be on.
This reinstates the update_layout and adds the following information to
the modesetting system.
a) Connection status <-> Equivalent to real hardware connection status
b) Preferred mode <-> Equivalent to real hardware reading EDID
c) Host window position <-> Equivalent to a real hardware scanout address
dynamic register.
It should be noted that there is no assumption here about what should be
displayed and where. Only how to access the host windows.
This also bumps minor to signal availability of the new IOCTL.

Rather than having a quirk list just always check the EDID header
when probing. This is the recommended behavior according to the
display team. This avoids problems with improperly terminated
i2c lines on some boards. This is also what the proprietary

The function didn't work with DP, eDP, or DP bridge
connectors and thus confused users as it lead them to
believe nothing was connected or the EDID was invalid
when in fact is was, just on the aux bus rather an i2c.
It should also speed up module loading as it avoids a
bunch of extra DDC probing.

The vram scratch was originally only used on some 7xx asics
to work around a hw bug. Allocate the scratch page on all 6xx+
radeons and set the MC_VM_SYSTEM_APERTURE_DEFAULT_ADDR to point
to it. We shouldn't ever hit it since we limit the system
aperture to vram or vram and AGP, but better safe than sorry.

hard-coded value 6
radeon_driver_irq_preinstall_kms and radeon_driver_irq_uninstall_kms
hard code the loop to 6 which happens to be the current maximum
number of crtcs and hpd pins; if one day an ASIC with more crtcs
(or hpd pins) comes out, this is a trouble waiting to happen.
introduce constants for maximum CRTC count, maximum HPD pins count
and maximum HDMI blocks count (per FIXME in radeon_irq structure)
and correct the loops in radeon_driver_irq_preinstall_kms and
radeon_driver_irq_uninstall_kms

Since force handling rework of d0d0a225e6ad43314c9aa7ea081f76adc5098ad4
we could end up bouncing connector status btw disconnected and unknown.
When connector status change a call to output_poll_changed happen which
in turn ask again for detect but with force set.
So set the load detect flags whenever we report the connector as
connected or unknown this avoid bouncing btw disconnected and unknown.

Make sure that the reset is successful by issuing a dummy read to R
channel current register and check its default value. On some platforms,
without this dummy read, any further access to {R/G/B}_EXEC will not have

Depending on the implementation of the hardware blinking function in
blink_set(), the led can support hardware blinking for some values of
delay_on and delay_off and fall-back to software blinking for some other
values.
Turning off the blink_timer unconditionally before starting to blink
make sure that a sequence like:
OFF
hardware blinking
software blinking
hardware blinking
does not leave the software blinking timer active.

When calling the hardware blinking function implemented by blink_set(),
the delay_on and delay_off values are not preserved across calls.
Fix that and make the "timer" trigger work as expected when hardware
blinking is available.
BEFORE the fix:
$ cd /sys/class/leds/someled
$ echo timer > trigger
$ cat delay_on delay_off
0

$ echo 100 > delay_on
$ cat delay_on delay_off
0

$ cat delay_on delay_off

$ cd /sys/class/leds/someled

$ echo 100 > delay_on
$ cat delay_on delay_off

My GPIOs are on an I2C port expander, so we must use the *_cansleep()
variant of the GPIO functions. This is was not being done in
create_gpio_led().
We can change gpio_get_value() to gpio_get_value_cansleep() because it is
only called from the platform_driver probe function, which is a context
where we can sleep.
Only tested on my gpio_cansleep() system, but it seems safe for all
systems.

According to the comments in include/linux/init.h:
"Pointers to __devexit functions must use __devexit_p(function_name), the
wrapper will insert either the function_name or NULL, depending on the config

We have __devexit annotation for lm3530_remove(), so add __devexit_p to
