All warnings (new ones prefixed by >>, old ones prefixed by <<):

>> WARNING: modpost: vmlinux.o(.text+0x3ac2): Section mismatch in reference from the function riscv_ipi_setup() to the function .init.text:sbi_ipi_init()
The function riscv_ipi_setup() references
the function __init sbi_ipi_init().
This is often because riscv_ipi_setup lacks a __init
annotation or the annotation of sbi_ipi_init is wrong.
