[PATCH] x86/mm/32: Fix -Wmissing prototypes warnings in init.c

[Benjamin Thiel]

Fix:

  arch/x86/mm/init.c:503:21:
  warning: no previous prototype for âinit_memory_mappingâ [-Wmissing-prototypes]
  unsigned long __ref init_memory_mapping(unsigned long start,

  arch/x86/mm/init.c:745:13:
  warning: no previous prototype for âpoking_initâ [-Wmissing-prototypes]
  void __init poking_init(void)

Lift init_memory_mapping() and poking_init() out of the ifdef CONFIG_X86_64 to
make the functions visible on 32-bit too.
