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.

This is only half the story I'm afraid. It doesn't take account of the
fact that the command line can be passed from the boot loader via the
ATAG structures, which are only parsed after the machine specific
fixup has happened (which can also modify the ATAGs).
You're also not guaranteed to have an ATAG list before setup_arch() is
called - it might be a param_struct, and we convert that to an ATAG list
before ATAG parsing.
So there's quite a bit which needs to be done to get at the command line.
Basically, what's required is:
- convert param struct to tag list
- if no tag list, use default tag list
- run machine specific fixups which may set memory layout
- if memory layout has been set, kill off any memory atags to prevent it
being overwritten
- parse all atags which includes setting the command line if such a tag
is found
Then, and only then can you be sure that you have the right command line.

Thanks for the clue donation. I've read the code harder now. Tricky.
OK, I think this is close. I'll grab a cross-compiler and build test at
least, and do a followup patch to switch those __early_param() to core_param
which will simplify this a little. I'll revert the cmdline() separation now
too, since it's unnecessary, but I have to go run errands for the rest of the
day :(
A couple of #if 0 around code I don't think can happen (even in the orignal
place I moved it from?)
Thanks!
Rusty.

I think avr32 might need something similar as it also gets the command
line from a tag list. But we never really do anything tricky with those
tags, so I think it should work to simply move the call to parse_tags()
from setup_arch() into arch_get_boot_command_line().

This prevents 'init_tags' from ever being used, which wil happen if
convert_to_tag_list() doesn't find a param_struct to convert.

This may happen if the memory pointed to by 'tags' gets overwritten for
some reason by a machine specific fixup, but that'll probably never
happen.

Ah, I missed this test in convert_to_tag_list:
if (params->u1.s.page_size != PAGE_SIZE) {
printk(KERN_WARNING "Warning: bad configuration page, "
"trying to continue\n");
return;
}
Here's the new arm version, followed by an __early_param conversion.
Compile-tested only.

arm: use generic early_param
early_param() was inspired by arm's __early_param: now it's called earlier
in generic code, it can be used by arm as well.
This also allows us to get rid of default_command_line.
A possible cleanup would be to have fortunet_fixup do the strlcpy into
boot_command_line itself, and remove the &cmdline arg to ->fixup.

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

Thanks Greg,
There are some minor mods, so I'll repost. You can ack that :)
I'll also create a git tree for archs to actually boot test. No doubt
there'll be more arch-specific fixes needed.
Thanks!
Rusty.

(All patches can be found in the git tree. Please test your arch before I break it in linux-next ;) git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux-2.6-boot-params.git )
This allows us to get the command line before setup_arch(): right atthe beginning of start_kernel(). It also cleans up chaoticcommandline handling.
This means most setup_arch boutique early cmdline handling can beturned into core_params or early_setup. This saves some bytes, andcore_param also gets them that optional sysfs presence.
I used fixme's to suggest further arch-specific cleanups.

Your patch is broken here:
missing header for unified diff at line 140 of patch
can't find file to patch at input line 140
Perhaps you used the wrong -p or --strip option?
The text leading up to this was:

File to patch: ^C
Has your email client wrapped a line?

Yes, and not the first time I forgot either :( I filed a wishlist bug
http://bugs.kde.org/show_bug.cgi?id=176833
Here it is again, hopefully fixed:
param: arch_get_boot_command_line()
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 or early_setup. This saves some bytes, and
core_param also gets them that optional sysfs presence.
I used fixme's to suggest further arch-specific cleanups.

I pulled your git tree. All my test configs build cleanly
for ia64 ... but sadly the first kernel I tested (generic_defconfig)
doesn't boot (no console output at all).
I'll see if I can figure out what is going on.

Aha. You are now calling machvec_init_from_cmdline() too early (before
efi_init() and io_port_init()) ... so we croak accessing things
that have not been set up. Naive fix is to just move them from
setup_arch() to arch_get_boot_command_line(). I can't see how to
handle this more cleanly given that you do the rest of the
command line parsing before calling setup_arch().

This exacerbates a long standing `problem' that linux_banner

gets moved down even further to the sixth line:

OK, both appended to git tree.

If noone else complains, I'll fold the fix and ask Stephen to take the tree
for linux-next.

I'm wondering whether the ia64 bits are now green, yellow or maybe they're
taking some terminal exercise by jumping off the cliff like lemmings.

Yeah, it's a fix commit. Git fits with arch maintainers' workflow most
easily so I use it here, but it leads to expectations about "append only".
I'll fold into a sane series before shovelling through linux-next; this
week I expect, since noone actually said "this is a stupid waste of time".
