Basically your patches are correct, but those structs aren't used
after bootup any longer.
So, they are much better placed in the __initconst or __initdata
sections so that they get dropped before the kernel enters userspace.
Changing it to __initconst includes more changes to those files
than just changing one line.

So, I won't apply your patches.
Instead I've hacked up new versions in my tree which move those to
__init* sections.

Anyway, thanks for your patches!
