Re: [RFC 5/8] param: arch_get_boot_command_line()

From: Greg Ungerer
Date: Tue Dec 02 2008 - 20:00:44 EST

Hi Rusty,

Rusty Russell wrote:
This allows us to get the command line before setup_arch(): right at
the beginning of start_kernel(). It also cleans up chaotic
commandline handling.

This means most setup_arch boutique early cmdline handling can be
turned into core_params. This saves some bytes, but also gets them
the optional sysfs presence.

I used fixme's to suggest further arch-specific cleanups.

Signed-off-by: Rusty Russell <rusty@xxxxxxxxxxxxxxx>

I don't see any problems with the m68knommu bits.
Are you looking for an acked-by?

Regards
Greg
