ARM has support for the atomic64_dec_if_positive operation
so ensure that it is tested by the atomic64_test routine.

Add s390 to list of architectures that have atomic64_dec_if_positive
implemented so we get rid of this warning:
lib/atomic64_test.c:129:2: warning: #warning Please implement
atomic64_dec_if_positive for your architecture, and add it to the IF above

missing include file (linux/kernel.h) for printk and KERN_INFO.

The x86-64 implementation of the atomics is totally different from the
i586+ implementation, which makes it quite confusing to call it
"586+". Also fix indentation, and add "i" for "i386" and "i586" as
used elsewhere in the kernel.

atomic64_inc_not_zero must return 1 if it perfomed the add and 0 otherwise.
The test assumed the opposite convention.

Add support for atomic_dec_if_positive(), and
atomic64_dec_if_positive() for x86-64.
atomic64_dec_if_positive() for x86-32 was already implemented in a previous patch.

This patch adds self-test on boot code for atomic64_t.
This has been used to test the later changes in this patchset.
