For the declaration above...

And this one... __initdata should come just before the '=', not at the
start, not in the middle and not before the variable.

The reasoning is that with how you have it above, the attributes are
applied to the structure.  You want to apply the attributes to the
declaration instead, so it should come after the variable name.

So, for example:

	struct foo *foo __attribute__((section(".foo"))) = (void *)1;

will place the "foo" variable into a section called ".foo", but:

	struct __attribute__((section(".foo"))) foo *foo = (void *)1;

will place "foo" into the normal .data section.

So, the rule with variable declarations is that the __ specifiers we
have as macros in the kernel always come after the variable name being
declared and nowhere else.  We consider anywhere else buggy.
