*	x86, atomic64: In selftest, distinguish x86-64 from 586+	H. Peter Anvin	2010-03-01
\| \| \| \| \| \| \| \| \| \| \|	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. Signed-off-by: H.

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

*	x86: Implement atomic[64]_dec_if_positive()	Luca Barbieri	2010-03-01
\| \| \| \| \| \| \| \| \| \| \|	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.

\| \| \| \| \| \| \| \| \|	Currently atomic64_dec_if_positive() is only supported by PowerPC, MIPS and x86-32. Signed-off-by: Luca Barbieri <luca@luca-barbieri.com> LKML-Reference: <1267183361-20775-1-git-send-email-luca@luca-barbieri.com> Signed-off-by: H. Peter Anvin <hpa@zytor.com>

	This patch adds self-test on boot code for atomic64_t. This has been used to test the later changes in this patchset. Signed-off-by: Luca Barbieri <luca@luca-barbieri.com> LKML-Reference: <1267005265-27958-4-git-send-email-luca@luca-barbieri.com> Signed-off-by: H. Peter Anvin <hpa@zytor.com>
