    vsprintf: Fix %ps on non symbols when using kallsyms · 2d168136

    Using %ps in a printk format will sometimes fail silently and
    print the empty string if the address passed in does not match a
    symbol that kallsyms knows about. But using %pS will fall back to
    printing the full address if kallsyms can't find the symbol. Make
    %ps act the same as %pS by falling back to printing the address.
    
    While we're here also make %ps print the module that a symbol
    comes from so that it matches what %pS already does. Take this
    simple function for example (in a module):
    
    	static void test_printk(void)
    	{
    		int test;
    		pr_info("with pS: %pS\n", &test);
    		pr_info("with ps: %ps\n", &test);
    	}

     with pS: 0xdff7df44
     with ps:
    
    After this patch:
    
     with pS: 0xdff7df44
     with ps: 0xdff7df44
