Kexec command line length

Hey all-
	Regarding this bug:
	http://bugzilla.kernel.org/show_bug.cgi?id=9641
	I'd like to look into putting together a patch for it, and wanted to
solicit comments for the best way to go about doing it.  Currently I've got it
fixed up in the Red Hat tree by bumping COMMAND_LINE_SIZE to 2048 and
eliminating the reserved buffer of the x86_linux_faked_param_header, which works
well, but isn't backwards compatible as Bernhard pointed out.  Given that extra
constraint, I thought it woudl e best to unify the command line and reserved
buffers in x86_linux_faked_param_header to one contiguour 2048 byte block and
maintain a separate variable that defines the command line length based on a
parsing of the UTS_VERSION.  Does that sound reasonable to everyone, or is there
a better way that someone has in mind?

Regards
Neil
