Cc'ing Kbuild folks. Question is: is there something wrong with writing stuff like this: obj-$(CONFIG_SATA_AHCI) += ahci.o libahci.o obj-$(CONFIG_SATA_AHCI_PLATFORM) += ahci_platform.o libahci.o as in drivers/ata/Makefile? It seem to link fine, .ko's are created. But for some reason initrd doesn't include these modules for Luming...
