Hi Andrew,

The kernel build fails, on powerpc while compiling the kernel with allyesconfig option

drivers/hwmon/w83627hf.c:1631: error: implicit declaration of function ‘acpi_check_resource_conflict’
make[2]: *** [drivers/hwmon/w83627hf.o] Error 1
make[1]: *** [drivers/hwmon] Error 2
make: *** [drivers] Error 2

The patches check-for-acpi-resource-conflicts-in-hwmon-drivers and 
check-for-acpi-resource-conflicts-in-i2c-bus-drivers.patch, causes this build failure.
The declaration of the functions are under ifdef CONFIG_ACPI.
