atomic64_test: simplify the #ifdef for atomic64_dec_if_positive() test

2012-07-31T00:25:16Z

Introduce CONFIG_ARCH_HAS_ATOMIC64_DEC_IF_POSITIVE and use this instead of the multitude of #if defined() checks in atomic64_test.c Signed-off-by: Catalin Marinas Cc: Russell King Cc: Ralf Baechle Cc: Benjamin Herrenschmidt Cc: Paul Mackerras Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

bug.h: add include of it to various implicit C users

2012-02-29T22:15:08Z

With bug.h currently living right in linux/kernel.h there are files that use BUG_ON and friends but are not including the header explicitly. Fix them up so we can remove the presence in kernel.h file. Signed-off-by: Paul Gortmaker

ARM: 6213/1: atomic64_test: add ARM as supported architecture

2010-07-27T09:43:46Z

ARM has support for the atomic64_dec_if_positive operation so ensure that it is tested by the atomic64_test routine. Acked-by: Nicolas Pitre Signed-off-by: Will Deacon Signed-off-by: Russell King

lib: add s390 to atomic64_dec_if_positive archs

2010-06-04T22:21:45Z

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 Signed-off-by: Heiko Carstens Cc: Luca Barbieri Cc: "H.

lib/atomic64_test: fix missing include of linux/kernel.h

2010-05-24T20:33:32Z

Fix a build-failure (http://kisskb.ellerman.id.au/kisskb/buildresult/2601239/) by adding the missing include file (linux/kernel.h) for printk and KERN_INFO.

x86, atomic64: In selftest, distinguish x86-64 from 586+

2010-03-01T19:51:56Z

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.

lib: Fix atomic64_inc_not_zero test

atomic64_inc_not_zero must return 1 if it perfomed the add and 0 otherwise. The test assumed the opposite convention. Signed-off-by: Luca Barbieri LKML-Reference: <1267469749-11878-5-git-send-email-luca@luca-barbieri.com> Signed-off-by: H. Peter Anvin

x86: Implement atomic[64]_dec_if_positive()

2010-03-01T19:38:42Z

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.
