[DECNET]: "addr" module param can't be __initdata
sysfs keeps references to module parameters via /sys/module/*/parameters,
so marking them as __initdata can't work.
Steps to reproduce:
modprobe decnet
cat /sys/module/decnet/parameters/addr
BUG: unable to handle kernel paging request at virtual address f88cd410
printing eip: c043dfd1 *pdpt = 0000000000004001 *pde = 0000000004408067 *pte = 0000000000000000
