This script cleans up various classes of stealth whitespace. In
particular, it cleans up:
- Whitespace (spaces or tabs)before newline;
- DOS line endings (CR before LF);
- Space before tab (spaces are deleted or converted to tabs);
- Empty lines at end of file.

Added the last definition and killed the input.h usage.

drivers/video/logo has references from .text to .init.data
but function is only used during early init.
So reference is OK and we do not want to warn about them =>
whitelist the reference.

Now where we do not pass vmlinux to modpost we started
to see section mismatch warnings from .pci_fixup.
Refactored code a little to include these in the
whitelist again.

In init/main.c we have a reference from rest_init() to .init.text
which is intentional.
Rename the function 'init' to 'kernel_init' to make it a
kernel wide unique symbol and whitelist the reference.

vmlinux does not contain relocation entries which is
used by the section mismatch checks.

Use the individual objects as inputs to overcome
this limitation.
In modpost check the .o files and skip non-ELF files.

o Some functions which are inline (acpi_madt_oem_check) are not inlined by
compiler as these functions are accessed using function pointer. These
functions are put in .text section and they in-turn access __init type
functions hence modpost generates warnings.
o Do not iniline acpi_madt_oem_check, instead make it __init.

Commit 2e3646e51b changed the way the
split config tree is built, but failed to also adjust fixdep accordingly
- if changing a config option from or to m, files referencing the
respective CONFIG_..._MODULE (but not the corresponding CONFIG_...)
didn't get rebuilt.
The problem is that trisate symbol are represent with three different
symbols:
SYMBOL=n => no symbol defined
SYMBOL=y => CONFIG_SYMBOL defined to '1'
SYMBOL=m => CONFIG_SYMBOL_MODULE defined to '1'
But conf_split_config do not distingush between the =y and =m case, so
only the =y case is honoured.
This is fixed in fixdep so when a CONFIG symbol with _MODULE is found we
skip that part and only look for the CONFIG_SYMBOL version.

This patch stops "modpost" from issuing erroneous modpost warnings on ARM
builds, which it's been doing since since maybe last summer. A canonical
example would be driver method table entries:
WARNING: <path> - Section mismatch: reference to .exit.text:<name>_remove
from .data after '$d' (at offset 0x4)
That "$d" symbol is generated by tools conformant with ARM ABI specs; in
this case it's a symbol **in the middle of** a "<name>_driver" struct.
The erroneous warnings appear to be issued because "modpost" whitelists
references from "<name>_driver" data into init and exit sections ... but
doesn't know should also include those "$d" mapping symbols, which are not
otherwise associated with "<name>_driver" symbols.
This patch prevents the modpost symbol lookup code from ever returning
those mapping symbols, so it will return a whitelisted symbol instead.
Then things work as expected.
Now to revert various code-bloating "fixes" that got merged because of this
modpost bug....

Fix a minor bug in mkcompile_h. As one can see, the current locale is used
while getting the version of gcc. This produces problems when a locale
other than C or en_US is used. As an example, my /proc/version contains
Turkish characters in iso-8859-9 encoding.
This patch fixes this issue by making sure that the C locale is used to get
gcc's version.

Check to see if `${CROSS_COMPILE}mkimage` exists and if not, fall back to
the standard `mkimage`
The Blackfin toolchain includes mkimage, but we dont want to namespace
collide with any of the user's system setup, so we prefix it with our
toolchain name.
