From d0729bc6bee797fb4bcca87583af5adbfe79ecfb Mon Sep 17 00:00:00 2001 From: Sergey Senozhatsky Date: Mon, 11 Dec 2017 21:50:25 +0900 Subject: arc: do not use __print_symbol() __print_symbol() uses extra stack space to sprintf() symbol information and then to feed that buffer to printk() char buffer[KSYM_SYMBOL_LEN]; sprint_symbol(buffer, address); printk(fmt, buffer); Replace __print_symbol() with a direct printk("%pS") call.
