pte alloc routines must wait for split_huge_page if the pmd is not present
and not null (i.e.  pmd_trans_splitting).  The additional branches are
optimized away at compile time by pmd_trans_splitting if the config option
is off.  However we must pass the vma down in order to know the anon_vma
lock to wait for.

Four architectures (arm, mips, sparc, x86) use __vmalloc_area() for
module_init().  Much of the code is duplicated and can be generalized in a
globally accessible function, __vmalloc_node_range().

__vmalloc_node() now calls into __vmalloc_node_range() with a range of
[VMALLOC_START, VMALLOC_END) for functionally equivalent behavior.

Each architecture may then use __vmalloc_node_range() directly to remove
the duplication of code.

Commit 6aa85a5a (omap4: 4430sdp:
enable the ehci port on 4430SDP) added code to enable EHCI
support on 4430sdp board.

Looks like the ULPI pin does not seem to be muxed properly on ES1.0
SDP and this causes the system to reboot when the ULPI PHY is
enabled.

Fix this by muxing the pin, this is the same setting for
both ES1.0 and ES2.0. Also add checking for gpio_request.

TFP410 DVI chip is used to provide display out.
This chip is controlled by 2 lines:
LDO which supplies the power is controlled over gpio + 2
and the enable of the chip itself is done over gpio + 1
NOTE: the LDO is necessary for LED, serial blocks as well.

gpio + 1 was used to sense USB overcurrent in vanilla beagle.

Without this fix, the display would not function as the LDO
remains shut down.

The second MMC channel (used by the WLAN/BT module) is not linked to
power regulator. This causes the WLAN/BT module to fail being detected if
CONFIG_REGULATOR_DUMMY is not set.

This patch adds the two regulators that actually feed the WLAN/BT module
(1v8 from the TWL4030 VIO LDO, and a fixed 3v3). With that patch, the
second channel is properly detected.

The SMSC 3320 USB PHY on the OMAP4 Pandaboard needs a 19.2 MHz
reference clock. This clock is provided from the OMAP4's fref_clk3
pad.

Recent changes to clock44xx_data.c made the clock framework aware
of the existence of these fref_clk[i] lines. If the option
CONFIG_OMAP_RESET_CLOCKS is enabled in the kernel, then the
clock framework will turn these clocks off during bootup.

Explicitly request and keep this clock enabled at init for the
Pandaboard, so that the PHY receives this clock at all times.

A panel connects to one of the overlay managers of DSS through some interface block.
On OMAP4, specifying the type of the display is not sufficient to conclude which manager
the panel should be connected to.
Hence, a new member 'channel' is introduced in omap_dss_device structure to determine
which manager the panel uses. The dss_recheck_connections() called in dss_driver_probe()
uses this channel parameter to set the correct manager to the corresponding omap_dss_device.

The channel parameter is used only once to ensure the correct managers are set for each
panel. The parameter dssdev->manager->id will take care of ensuring that the panel and
then the interface driver configures the correct DISPC channel.

Also, add a new Overlay Manager in manager.c, make other changes needed for LCD2 channel.

On OMAP4, we have a new DISPC channel for Overlay Manager LCD2. There is a set
of regsiters for LCD2 channel similar to the existing LCD channel, like
DISPC_CONTROL2, DISPC_DIVISOR2, DISPC_CONFIG2 and so on.

Introduce new enum members for LCD2 Channel and corresponding Overlay Manager
in display.h.

Represent the following DISPC register defines with channel as a parameter
to differentiate between LCD and LCD2 registers (and also DIGIT in some cases):

DISPC_DEFAULT_COLOR, DISPC_TRANS_COLOR, DISPC_TIMING_H, DISPC_TIMING_V,
DISPC_POL_FREQ, DISPC_DIVISOR, DISPC_SIZE_LCD, DISPC_DATA_CYCLEk,
DISPC_CPR_COEF_R, DISPC_CPR_COEF_G and DISPC_CPR_COEF_B

This parametrization helps in reducing the number of register defines for DISPC.
Replace the existing reads/writes to these registers in this new way.
Also, Introduce defines for registers DISPC_CONTROL2 and DISPC_CONFIG2 which
are used exclusively for LCD2 channel.
