Subject: [PATCH 1/1]     Loongson: Fix section mismatch warning

    init_numa_memory() is annotated __init and not used by any module,
    thus don't export it.

    Remove not needed EXPORT_SYMBOL for init_numa_memory() to fix the
    following section mismatch warning:

  CHK     include/generated/compile.h
  UPD     include/generated/compile.h
  CC      init/version.o
  AR      init/built-in.a
  LD      vmlinux.o
  MODPOST vmlinux.symvers
WARNING: modpost: vmlinux.o(___ksymtab+prom_init_numa_memory+0x0): Section mismatch in reference from the variable __ksymtab_prom_init_numa_memory to the function .init.text:prom_init_numa_memory()
The symbol prom_init_numa_memory is exported and annotated __init
Fix this by removing the __init annotation of prom_init_numa_memory or drop the export.

  MODINFO modules.builtin.modinfo
  GEN     modules.builtin

    This is build on Linux 5.19-rc5.
