Let me try to make it a bit easier yet: here are the biuld failures from 
both platforms:

mackerel:

arch/arm/mach-shmobile/built-in.o: In function `mackerel_sdhi0_gpio_cd':
pfc-sh7372.c:(.text+0x1138): undefined reference to `mmc_detect_change'

ag5evm:

arch/arm/mach-shmobile/built-in.o: In function `ag5evm_sdhi0_gpio_cd':
pfc-sh73a0.c:(.text+0x7c0): undefined reference to `mmc_detect_change'

Also attaching to this email the patches with added patch descriptions and 
these error-logs.

Thanks
