Because lib/test_printf.c wants to use no_hash_pointers for testing purpose, and lib/test_printf.c might be built as a loadable kernel module. That is, no_hash_pointers is not meant for general use.
config TEST_PRINTF tristate "Test printf() family of functions at runtime"
obj-$(CONFIG_TEST_PRINTF) += test_printf.o
