Subject: [PATCH] vsprintf: fix gcc warning

The patch

commit bf4bb495e5dc8f1abba98bb6cb08b2d94446a662
Author: Linus Torvalds <>
Date: Sat Jul 5 22:37:13 2008 -0700

printk: add support for '%pS'

introduced a new build warning from GCC (4.1.2):

CC lib/vsprintf.o
lib/vsprintf.c: In function `pointer':
lib/vsprintf.c:560: warning: cast from pointer to integer of different size

Whether the warning is useful or not is a discussion on its own. But
we can at least fix this by casting to 'unsigned long' instead of
'unsigned long long'. 'unsigned long' can hold a pointer and will be
converted implicitly to the right type upon calling the function.
