Subject: [PATCH 5.19 0935/1157] MIPS: Loongson64: Fix section mismatch warning

From: Tiezhu Yang <yangtiezhu@...ngson.cn>

[ Upstream commit 08472f6ebdc23334ad11dcd761d2d52c32897793 ]

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

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

  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.

This is build on Linux 5.19-rc4.
