#     powerpc/kexec_file: fix implicit decl error
#     
#     kexec (PPC64) code calls memory_hotplug_max(). Add the header
#     declaration for it from <asm/mmzone.h>. Using <linux/mmzone.h> does not
#     work since the #include for <asm/mmzone.h> depends on CONFIG_NUMA=y,
#     which is not always set.
#     
#     Fixes this build error/warning:
#     
#       arch/powerpc/kexec/file_load_64.c: In function 'kexec_extra_fdt_size_ppc64':
#       arch/powerpc/kexec/file_load_64.c:993:33: error: implicit declaration of function 'memory_hotplug_max'
#       993 |                 usm_entries = ((memory_hotplug_max() / drmem_lmb_size()) +
#           |                                 ^~~~~~~~~~~~~~~~~~
