[PATCH] /fs/proc/: 'larger than buffer size' memory accessed by clear_user()

Address a potential 'larger than buffer size' memory access by
clear_user().  Without this patch, this call to clear_user() can attempt to
clear too many (tsz) bytes resulting in a wrong (-EFAULT) return code by
read_kcore().
