Shift the contents of module.h and moduleparam.h so that generic
module content is exclusively in module.h, while parameter-specific
content is in moduleparam.h.
Signed-off-by: Robert P. J. Day <[email protected]>
---
while this patch makes the contents of module.h and moduleparam.h
somewhat more organized, it still has the weird property that each of
those two files includes the other. given the current state of
includes throughout the source tree, there's not much that can be done
about that at the moment.
compile-tested with "make allmodconfig" on x86.
