on x86, there are some issues with drivers/platform/olpc/olpc-xo175-ec.c:

a. when CONFIG_SPI is not set/enabled:

WARNING: unmet direct dependencies detected for SPI_SLAVE
  Depends on [n]: SPI [=n]
  Selected by [y]:
  - OLPC_XO175_EC [=y] && (ARCH_MMP || COMPILE_TEST [=y])

ld: drivers/platform/olpc/olpc-xo175-ec.o: in function `olpc_xo175_ec_remove':

ld: drivers/platform/olpc/olpc-xo175-ec.o: in function `olpc_xo175_ec_cmd':

olpc-xo175-ec.c:(.init.text+0xa): undefined reference to `__spi_register_driver'

b. when CONFIG_INPUT is not set/enabled:

ERROR: "input_register_device" [drivers/platform/olpc/olpc-xo175-ec.ko] undefined!
ERROR: "input_set_capability" [drivers/platform/olpc/olpc-xo175-ec.ko] undefined!

ERROR: "input_event" [drivers/platform/olpc/olpc-xo175-ec.ko] undefined!

c. when some power mgt. Kconfig symbol is not set/enabled:

ERROR: "power_supply_put" [drivers/platform/olpc/olpc-xo175-ec.ko] undefined!
ERROR: "power_supply_changed" [drivers/platform/olpc/olpc-xo175-ec.ko] undefined!
ERROR: "power_supply_get_by_name" [drivers/platform/olpc/olpc-xo175-ec.ko] undefined!

d. drivers/platform/olpc/Kconfig needs to use "menuconfig" like all of the other
   Kconfig files in drivers/platform/ so that its menu is listed in the correct
   place in *config interfaces.
