This patch adds a set of macros that can be used to declare
kernel parameters to be parsed _before_ initcalls at a chosen
level are executed. Such parameters are marked using existing
"flags" field of the "kernel_param" structure.

Linker macro collating init calls had to be modified in order
to add additional symbols between levels that are later used
by the init code to split the calls into blocks.

This patch wasn't quite what I was thinking, but I've realized that
we can't put the params in the .init section, your approach is probably
the best one.

Note that I've just created a series which gets rid of that silly ISBOOL
thing, so you can use the whole field for "level".  Then I set the level
to -1 for the normal calls; I want to use -2 for the early calls, but
that's not done yet...

I'll rework and rebase your patch like that now.

Thanks!
Rusty.
