[PATCH 00/26] Dynamic kernel command-line

Current implementation stores a static command-line
buffer allocated to COMMAND_LINE_SIZE size. Most
architectures stores two copies of this buffer, one
for future reference and one for parameter parsing.

In order to allow a greater command-line size, these
buffers should be dynamically allocated or marked
as init disposable buffers, so unused memory can be
released.

This patch renames the static saved_command_line
variable into boot_command_line adding __initdata
attribute, so that it can be disposed after
initialization. This rename is required so applications
that use saved_command_line will not be affected
by this change.

It reintroduces saved_command_line as dynamically
allocated buffer to match the data in boot_command_line.

It also mark secondary command-line buffer as __initdata,
and copies it to dynamically allocated static_command_line
buffer components may hold reference to it after
initialization.

This patch is for linux-2.6.18-rc5-mm1 and is divided to
target each architecture. I could not check this in any
architecture so please forgive me if I got it wrong.
