With various firmware files used by graphics and wireless drivers we are exceeding the current 32 character module name (file path in kldxref) length. In order to overcome this issue bump it to the maximum path length for the next version. To be able to MFC provide backward compat support for another version of the struct as the offsets for the second half change due to the array size increase. MAXMODNAME being defined to MAXPATHLEN needs param.h to be included first. With only 7 modules (or LinuxKPI module.h) not doing that adjust them rather than including param.h in module.h [1].
