v5 release changes. Generally a rebase from v4.

* Modified OF changes to move the ugly code into the cmdline.h

* Minor compliation update in arm64. Added ifndef __ASSEMBLY__ in
  a few places.

* Worked around arm64 kaslr_early.c.

	This code needs some additional review and consideration. 
	It appears this code is missing the opposite option to nokaslr
	which is kaslr.disabled=1/0 which would allow kaslr to be turn
	back on later in the command line. For example,

	console=ttyS0 nokaslr root=/dev/ram0 nosmp kaslr.disabled=0 loglevel=7
	
	On arm64 in arch/arm64/kernel/idreg-override.c this is parsed correctly
	to turn on kaslr, but the kaslr_early.c is missing this logic.
	Doing this results in kaslr getting disabled with the following message,

	KASLR disabled due to lack of seed

	Even when there is a seed in the device tree.	

	So change to the generic command line would leave built in command
	lines with nokaslr with no option to re-enable kaslr in in the bootloader
	arguments.

This updates the mips code to use the CONFIG_GENERIC_CMDLINE
option.

This deletes the option for MIPS_CMDLINE_BUILTIN_EXTEND
and replaces the functionality with generic code.

Of note, the pic32 has some strange handling of the current built
in command line. It was converted to use the static variant which
can't be updated after compilation. It should eventually be updated
to use to append and prepend symbols.

This includes a scripted mass convert of the config files to use
the new generic cmdline. There is a bit of a trim effect here.
It would seems that some of the config haven't been trimmed in
a while.

The script used is as follows,

if [[ -z "$1" || -z "$2" ]]; then
        echo "Two arguments are needed."
        exit 1
fi
mkdir $1
cp $2 $1/.config
sed -i 's/CONFIG_CMDLINE=/CONFIG_CMDLINE_BOOL=y\nCONFIG_CMDLINE_PREPEND=/g' $1/.config
make ARCH=$1 O=$1 olddefconfig
make ARCH=$1 O=$1 savedefconfig
cp $1/defconfig $2
rm -Rf $1

This updates the mips code to use the CONFIG_GENERIC_CMDLINE
option.

This deletes the option for MIPS_CMDLINE_BUILTIN_EXTEND
and replaces the functionality with generic code.

Of note, the pic32 has some strange handling of the current built
in command line. It was converted to use the static variant which
can't be updated after compilation. It should eventually be updated
to use to append and prepend symbols.

This includes a scripted mass convert of the config files to use
the new generic cmdline. There is a bit of a trim effect here.
It would seems that some of the config haven't been trimmed in
a while.

The script used is as follows,

if [[ -z "$1" || -z "$2" ]]; then
        echo "Two arguments are needed."
        exit 1
fi
mkdir $1
cp $2 $1/.config
sed -i 's/CONFIG_CMDLINE=/CONFIG_CMDLINE_BOOL=y\nCONFIG_CMDLINE_PREPEND=/g' $1/.config
make ARCH=$1 O=$1 olddefconfig
make ARCH=$1 O=$1 savedefconfig
cp $1/defconfig $2
rm -Rf $1

This updates the mips code to use the CONFIG_GENERIC_CMDLINE
option.

This deletes the option for MIPS_CMDLINE_BUILTIN_EXTEND
and replaces the functionality with generic code.

Of note, the pic32 has some strange handling of the current built
in command line. It was converted to use the static variant which
can't be updated after compilation. It should eventually be updated
to use to append and prepend symbols.

This includes a scripted mass convert of the config files to use
the new generic cmdline. There is a bit of a trim effect here.
It would seems that some of the config haven't been trimmed in
a while.

The script used is as follows,

if [[ -z "$1" || -z "$2" ]]; then
        echo "Two arguments are needed."
        exit 1
fi
mkdir $1
cp $2 $1/.config
sed -i 's/CONFIG_CMDLINE=/CONFIG_CMDLINE_BOOL=y\nCONFIG_CMDLINE_PREPEND=/g' $1/.config
make ARCH=$1 O=$1 olddefconfig
make ARCH=$1 O=$1 savedefconfig
cp $1/defconfig $2
rm -Rf $1
