If userspace (plymouth in this case) asks for a deeper depth,
refuse it as well due to lack of resizing.
This fixes an issue since < 32MB cards went to 8bpp and plymouth
crashes on startup.

With the current DRM code, an output that has been powered off
from userspace will automatically power back on when resuming
from suspend. This patch fixes this behaviour.
Tested only with the Intel i915 driver on an Intel GM45 Express
chipset.

The id_table field of the struct pci_driver is constant in <linux/pci.h>
so it is worth to make pci_device_id also constant.

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 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.

if we enable CPUFREQ we can't build omap2 for two reasons,
one of them is fixed by the patch below.
It's failing because the __must_be_array() check in

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.

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.

Some chips, namely any OMAP1 chips using METHOD_MPUIO,
OMAP15xx and OMAP7xx, cannot be setup to respond to on-chip GPIO
interrupts in both rising and falling edge directions -- they can
only respond to one direction or the other, depending on how the
ICR is configured.
Additionally, current code forces rising edge detection if both
flags are specified:
if (trigger & IRQ_TYPE_EDGE_RISING)
l |= 1 << gpio;
else if (trigger & IRQ_TYPE_EDGE_FALLING)
l &= ~(1 << gpio);
else
goto bad;
This change implements a toggle function that will modify the ICR
to flip the direction of interrupt for IRQs that are requested with
both rising and falling flags. The toggle function is not called
for chips and GPIOs it does not apply to through the use of a flip_mask
that's added on a per-bank basis. The mask is only set for those
GPIOs where a toggle is necessary. Edge detection starts out the
same as above with FALLING mode first.
The toggle happens on EACH interrupt; without it, we have the
following sequence of actions on GPIO transition:
ICR GPIO Result
0x1 0 -> 1 (rising) Interrupt
0x1 1 -> 0 (falling) No interrupt
(set ICR to 0x0 manually)
0x0 0 -> 1 (rising) No interrupt
0x0 1 -> 0 (falling) Interrupt
That is, with the ICR set to 1 for a gpio, only rising edge interrupts
are caught, and with it set to 0, only falling edge interrupts are
caught. If we add in the toggle, we get this:
ICR GPIO Result
0x1 0 -> 1 (rising) Interrupt (ICR set to 0x0)
0x0 1 -> 0 (falling) Interrupt (ICR set to 0x1)
0x1 0 -> 1 ...
so, both rising and falling are caught, per the request for both
(IRQ_TYPE_EDGE_RISING | IRQ_TYPE_EDGE_FALLING).

In its current form, the omap_mcbsp_request() function can return after
irq_request() failure without any cleanups, effectively locking out the port
forever with clocks left running. Fix it.

Access to the ASB2305's PCnet32 NIC doesn't work correctly because when
the NIC attempts to update the ring buffer flags by DMA, the change to RAM
crops up about 17uS after the interrupt line is asserted. This is almost
certainly due to a bug in the PCI bridge FPGA on that board.
We can get around this by making dma_alloc_coherent() put the ring buffer
in the SRAM attached to the PCI bridge rather than in the SDRAM.

Insert PCI root bus resources for the MN10300-based ASB2305 development
kit motherboard. This is required because the CPU's window onto the PCI
bus address space is considerably smaller than the CPU's full address
space and non-PCI devices lie outside of the PCI window that we might want
to access.
Without this patch, the PCI root bus uses the platform-level bus
resources, and these are then confined to the PCI window, thus making
platform_device_add() reject devices outside of this window.
We also add a reservation for the PCI SRAM region.

Use the generic pci_enable_resources() instead of the arch-specific code.
Unlike this arch-specific code, the generic version:
- checks PCI_NUM_RESOURCES (11), not 6, resources
- skips resources that have neither IORESOURCE_IO nor IORESOURCE_MEM set
- skips ROM resources unless IORESOURCE_ROM_ENABLE is set
- checks for resource collisions with "!r->parent"

gcc 4.2.1 for MN10300 is more agressive than the older gcc in
reordering/moving other insns between an insn that sets flags and an insn
that uses those flags. This leads to trouble with asm statements which
are missing an explicit "cc" clobber. This patch adds the explicit "cc"
clobber to asm statements which do indeed clobber the condition flags.

This fixes a signal stack handling problem in the MN10300 arch. When new
threads are cloned with CLONE_VM, they don't inherit the alternate signal
stack. They do share the signal flags, though. When deciding whether to
use an alternate stack, the arch code needs to check to make sure the task
struct contains a valid alternate stack. This patch fixes the MN10300
arch by using the sas_ss_flags() test provided by sched.h rather than the
on_sig_stack() test which is insufficient by itself.
