$ git grep -w IBMEBUS
arch/powerpc/platforms/Kconfig:config IBMEBUS
drivers/net/ethernet/ibm/Kconfig:       depends on PPC_PSERIES || PPC_DCR || (IBMEBUS && SPARSEMEM)
drivers/net/ethernet/ibm/Kconfig:       depends on IBMEBUS && SPARSEMEM
drivers/staging/rdma/ehca/Kconfig:      depends on IBMEBUS

Nothing "odd" about this, why the confusion?
