From: Randy Dunlap <[EMAIL PROTECTED]> NTFS (=m) uses hweight32(), but that function is only linked into the kernel image if it is used inside the kernel image, not in loadable modules. Let modules force HWEIGHT to be built into the kernel image. Otherwise build fails:
Building modules, stage 2. MODPOST 94 modules WARNING: "hweight32" [fs/ntfs/ntfs.ko] undefined! Yes, I'd certainly prefer for this to be more automated rather than forced by each module that needs it.
