[ Upstream commit b899981750dcb958ceffa4462d903963ee494aa2 ]
As reported by the kernel test robot, the following error occurs:
arch/parisc/kernel/pdt.c:65:6: warning: no previous prototype for 'arch_report_meminfo' [-Wmissing-prototypes] 65 | void arch_report_meminfo(struct seq_file *m) | ^~~~~~~~~~~~~~~~~~~
arch_report_meminfo() is declared in include/linux/proc_fs.h and only defined when CONFIG_PROC_FS is enabled. Wrap its definition in #ifdef CONFIG_PROC_FS to fix the -Wmissing-prototypes warning.
