If for any reason we haven't installed handler we shouldn't try to
enable IRQ/MSI on the hw so we don't get unhandled IRQ/MSI which
makes the kernel sad.

In some case vblank might not be initialized and we shouldn't
try to use associated function. This patch make sure this is
the case. It also export drm_vblank_cleanup so driver can cleanup
vblank if for any reason IRQ/MSI is not working.

In some case we weren't releasing the AGP device at module unloading.
This leaded to unfunctional AGP at next module load. This patch make
sure we release the AGP bus if we acquire it.

R300 family will hard lockup if host path read cache flush is
done through MMIO to HOST_PATH_CNTL. But scheduling same flush
through ring seems harmless. This patch remove the hdp_flush
callback and add a flush after each fence emission which means
a flush after each IB schedule. Thus we should have same behavior
without the hard lockup.
Tested on R100,R200,R300,R400,R500,R600,R700 family.

Long story short, this fixes sporadic hardlocks with my rv410 during
times of intense 2D acceleration (Flash on Fx3).
V2: Fix indentation and move errata_fini to suspend function so we
don't leak scratch register over suspend/resume cycle.
V3: Move scratch_reg to asic specific structure (aim is to slowly
move stuff to asic specific structure and avoid poluting
radeon_device struct with asic specific variables)

There are a couple of array overruns, and some associated confusion in

The max junction temperature of Atom N450/D410/D510 CPUs is 100 degrees
Celsius. Since these CPUs are always coupled with Intel NM10 chipset in
one package, the best way to verify whether an Atom CPU is N450/D410/D510
is to check the host bridge device.

Expose the raw GGRP/GITM interface via debugfs. The hwmon interface is
reverse engineered and the driver tends to break on newer boards...
Using this interface it's possible to poke directly at the ACPI methods
without the need to recompile, reducing the guesswork and the round trips
needed to support a new revision of the interface.

The behaviour is unmodified, this makes easier to override the heuristic (which

The list macros use LIST_POISON1 and LIST_POISON2 as undereferencable
pointers in order to trap erronous use of freed list_heads. Unfortunately
userspace can arrange for those pointers to actually be dereferencable,
potentially turning an oops to an expolit.
To avoid this allow architectures (currently x86_64 only) to override
the default values for these pointers with truly-undereferencable values.
This is easy on x86_64 as the virtual address space is large and contains
areas that cannot be mapped.
Other 64-bit architectures will likely find similar unmapped ranges.

Dynamically allocate the CPUFreq frequency table on OMAP2xxx chips.
This fixes some compilation problems, since the kernel may not know
what chip it is running on until boot-time. This also reduces the size
of the CPUFreq frequency table.
Problem originally reported by Felipe Balbi <felipe.balbi@nokia.com>.
Thanks also for comments on the patch from Felipe and Kevin.

A subsequent patch adds code on OMAP2xxx to dynamically allocate the
CPUFreq frequency table in clk_init_cpufreq_table(), so for it to
avoid a leak, it will need a corresponding function to free the
memory. This patch adds clk_exit_cpufreq_table() with generic
code to call a chip-specific variant inside the clockfw_lock spinlock via
struct clk_functions.

Commit 52650505fbf3a6ab851c801f54e73e76c55ab8da added an __initdata
decoration to the structure containing the clk_enable and clk_disable
functions. Once init data was freed, these pointers went to null, and
the next enable or disable call caused the kernel to crash. This
change removes this decoration.

This change adds in some missing clocks that were needed as a result
of 526505... (OMAP1 clock: convert mach-omap1/clock.h to
mach-omap1/clock_data.c). Prior to this, it was just assumed that
these clocks existed for all devices, and it was used directly instead
of calling it out with a clock_get call or similar. So, not having
the CK_7XX meant these clocks weren't being used anymore for omap 7xx
devices, which broke things badly.

The only symbols that should be exported are symbols that are to be
called from loadable kernel modules, e.g., device drivers. In the
context of plat-omap/clock.c, these should only be the Linux clock
interface symbols as defined by include/linux/clk.h. Core code
doesn't need these symbols to be exported. Also, clean up an old
comment while here.

CORE_96M_FCLK
The correct parent of the McBSP 2, 3, and 4 functional clocks is
PER_96M_FCLK, not CORE_96M_FCLK. Fix this in the OMAP clock tree.

Commit 10db25fea4c11661070b97832b8cc3d2af495092 causes the following
kernel messages during N800 boot (and presumably all other 2420
boards):

[ 0.000000] BUG: mapping for 0x5a000000 at 0xe2000000 overlaps vmalloc space

Out of the three major OMAP2 chip types, OMAP2420, OMAP2430, and OMAP3430,
we only map the IVA on OMAP2420. The memory mapping is not shared between
OMAP2420 and OMAP2430, so it is inappropriate to label those macros as
'24XX'; this patch changes them to '2420'.

In OMAP2/3 some of the clock-domains which did not have control
facility were being falsely written to and read using the CM_CLKSTCTRL
register though it did not exist for them. One check is added to remove
this flaw.

Keys: 'right arrow', 'up arrow' and 'select' were mapped
wrongly. This patch corrects them.
This patch also adds one missing key present in the board,
currently I added it as 'unknown' key, as I am not able to
find proper description for this key.
One key entry (r: 7, c: 5) is present in the keymap, which
is really not present in the board, removing it.

Commit f62349ee9788b1d94c55eb6c291d74a1f69bdd9e makes it possible to
have some other than first uart port as ttyS0, which breaks the workaround
serial_in_override() function which will try to address the first uart
port (for ttyS0) and not the one that was initialized.

Commit 9905a43b made struct backlight_ops const. Omap was
setting check_fb dynamically, which caused the following
compile error:
drivers/video/backlight/omap1_bl.c: In function 'omapbl_probe':
drivers/video/backlight/omap1_bl.c:142: error: assignment of read-only variable 'omapbl_ops'
Turns out pdata->check_fb is not being used, so just remove
it to fix the compile.
