Subject: [PATCH 0/8] generic command line v4


v4 release changes

* Updated insert-sys-cert tool to change command line symbols after
  compilation.

	This tool is used to release binary kernels internally to companies
	and then later insert certificates for each product by consumers of
	the binary kernel. Cisco uses this tool for this purpose.

	Cisco has a similar need for the command line to be modified on a
	binary released kernels similar to how certificates are setup.

* Added global symbols to hold append and prepend values.

	These changes follow the system certificate code to allow the
	insert-sys-cert tool to be used.

* Added a test case to confirm functionality.

	Seemed sensible to add this to make sure everything is working.

* Dropped powerpc changes

	Christophe Leroy has reservations about the features for powerpc. I
	don't think his reservations are founded, and these changes should
	fully work on powerpc. However, I dropped these changes so Christophe
	can have more time to get comfortable with the changes.


Enjoy!
