Hello Jody,
Reducing the kernel size by making it less verbous looks fine, but I
think the option is misnamed and that could lead to confusion. A newbie
like me would understand that option as "reduce the kernel features to
gain space", not the amount of traces. So I would rename it something
like "VERBOSE_LESS" ?
Also, could it be possible to make such changes like this latest one in
another development branch, so that we could have a stable master
branch, as the official Linux, so that we could review, test, validate
and mature the changes on our different platforms before merging them ?
Regards,
Marc-F. Lucca-Daniau

I've added a new kernel configuration option that reduces the size of
the kernel without harmfully changing kernel functionality.
CONFIG_SMALL_KERNEL will turn off some unnecessary informational
driver initialization messages and the code that is used to generate
them. This will be expanded as I find more opportunities in the code
to apply it. For now, if you use the current git snapshot with and
without this option selected, the results will be something like this:
text data bss dec
55840 6984 50884 113708 CONFIG_SMALL_KERNEL=n
55152 6720 50884 112756 CONFIG_SMALL_KERNEL=y
-688 -264 0 -952 Change
I also updated the kernel defconfig to match currently available
options and cleaned out some junk kernel config options that were not
referenced anywhere in the actual code.
