If building with -fdata-sections on riscv, LD_ORPHAN_WARN will warn
similar as below:

riscv64-linux-gnu-ld: warning: orphan section `.init.data.efi_loglevel'
from `./drivers/firmware/efi/libstub/printk.stub.o' being placed in
section `.init.data.efi_loglevel'

I believe this is caused by a a typo:
init.data.* should be .init.data.*
