Subject[PATCH 03/13] c6x: do not use print_symbol()
Date
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.
