The system to allow panel drivers to exists as attached to ctrl drivers
did never work very well. It is not useed, and this patch removes it to
make the driver cleaner.
For now, controller drivers need to include also the panel driver code. In
the future a proper mechanism for this should be developed, perhaps by
creating busses for controllers.

This implements a bit of rework for the PMB code, which permits us to
kill off the legacy PMB mode completely. Rather than trusting the boot
loader to do the right thing, we do a quick verification of the PMB
contents to determine whether to have the kernel setup the initial
mappings or whether it needs to mangle them later on instead.
If we're booting from legacy mappings, the kernel will now take control
of them and make them match the kernel's initial mapping configuration.
This is accomplished by breaking the initialization phase out in to
multiple steps: synchronization, merging, and resizing. With the recent
rework, the synchronization code establishes page links for compound
mappings already, so we build on top of this for promoting mappings and
reclaiming unused slots.
At the same time, the changes introduced for the uncached helpers also
permit us to dynamically resize the uncached mapping without any
particular headaches. The smallest page size is more than sufficient for
mapping all of kernel text, and as we're careful not to jump to any far
off locations in the setup code the mapping can safely be resized
regardless of whether we are executing from it or not.

We broke "acpi=ht" in 2.6.32 by disabling MADT parsing
for acpi=disabled. e5b8fc6ac1
This also broke systems which invoked acpi=ht via DMI blacklist.
acpi=ht is a really ugly hack,
but restore it for those that still use it.

The PMB code is an example of something that spends an absurd amount of
time running uncached when only a couple of operations really need to be.
This switches over to the shiny new uncached helpers, permitting us to
spend far more time running cached.
Additionally, MMUCR twiddling is perfectly safe from cached space given
that it's paired with a control register barrier, so fix that up, too.

There are lots of registers that can only be updated from the uncached
mapping, so we add some helpers for those cases in order to make it
easier to ensure that we only make the jump when it's absolutely
necessary.

When we restore the screen content after a mode change, we return the
cursor to its former position. However, we need to also update
boot_params.screen_info accordingly, so that the decompression code
knows where on the screen the cursor is. Just in case the video BIOS
does something extra screwy, read the cursor position back from the
BIOS instead of relying on it doing the right thing.
While we're at it, make sure we cap the cursor position to the new
screen coordinates.

Add nr_cpus= to set nr_cpu_ids. so we can simulate cpus <=8 are installed on

This is a fix for bug #14845 (bugzilla.kernel.org). The update_checksum()
function in mm/kmemleak.c calls kmemcheck_is_obj_initialised() before scanning
an object. When KMEMCHECK_PARTIAL_OK is enabled, this function returns true.
However, the crc32_le() reads smaller intervals (32-bit) for which
kmemleak_is_obj_initialised() may be false leading to a kmemcheck warning.
Note that kmemcheck_is_obj_initialized() is currently only used by
kmemleak before scanning a memory location.

The check for a valid mux name should be performed regardless of whether

Unable to handle kernel NULL pointer dereference at virtual address 00000000
pgd = c0004000
[00000000] *pgd=00000000
Internal error: Oops: 5 [#1]
last sysfs file:

PC is at strcmp+0x18/0x40

This fixes the issue currently seen with boards not booting up
if DEBUG_FS is not enabled in defconfig.
Note that the earlier ifndef + ifdef now becomes simpler ifdef else:
If CONFIG_OMAP_MUX is selected, we use pin names. If it's not selected,
