I run out of module space because I have several big driver modules.
I know I can strip the modules to decrease size but I need debug info now.

The default size of module is 16MB and the size is statically defined in the
header file. 
But a description for the module space size tells that it can be
configurable at most 32MB.

I have changed the module space size to 18MB and tested my platform.
It has been looking good.

I am not sure my patch is proper solution.
Anyway, could I configure the module space size?

Or could I place the modules into vmalloc area?
Aside from the good comments that Russell made, I would remark that the
fact that you need multiple megabytes worth of modules indicates that you
are doing something wrong. Can you point to a git tree containing those
modules?
