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()) + | ^~~~~~~~~~~~~~~~~~ Fixes: fc546faa5595 ("powerpc/kexec_file: Count hot-pluggable memory in FDT estimate") Signed-off-by: Randy Dunlap <rdunlap@infradead.org> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://lore.kernel.org/r/20230204172206.7662-1-rdunlap@infradead.org
