This allows passing arrays of const pointers.  The goal is to make
lots of global variables "const" to allow them to live in the
".rodata" section.

In my opinion this touches way too many subsystems in a single patch.
If someting is wrong with just one of the changes, it will be all but
impossible to revert the whole thing.

Also, I don't know why checkpatch is happy with all the

	const struct attribute_group *const*groups;

instead of

	const struct attribute_group *const *groups;

but I still don't like it.

I wasn't sure whether splitting patches was desired. In the past, I
was often asked to fold multiple patches into one. There are so many
opinions :-) but I'll gladly change to whatever is asked.

No. I'll change the coding style (and maybe take some time to fix checkpatch?)

I found out that checkpatch has no check for this at all; it does
complain about such lines, but only for local variables. But that
warning is actually a bug, because this is a check for unary
operators: it thinks the asterisk is a dereference operator, not a
pointer declaration, and complains that the unary operator must be
preceded by a space. Thus warnings on local variable are only correct
by coincidence, not by design.

Inside structs or parameters (where my coding style violations can be
found), it's a different context and thus checkpatch doesn't apply the
rules for unary operators.

Ok, checkpatch support isn't always required, we can notice that changes
like this obviously are not sane and shouldn't be allowed just by
reading them :)

thanks,

My opinion is that const use in the kernel should almost
always have whitespace before and after it except when
preceded by a open parenthesis or a newline.

I totally agree.
