From: H. Peter Anvin on 23 Feb 2010 17:50 Hi Luca, I wonder if I could ask you to recreate your patchset on top of the x86/asm branch in the -tip tree. There are some nontrivial changes to the alternatives mechanism, plus a restructuring of the atomic headers which both conflict with this patchset. The -tip tree is available from: git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip.git -- H. Peter Anvin, Intel Open Source Technology Center I work for Intel.

That function is implemented in the generic atomic64 implementation and my x86-32 version, but not in the x86-64 implementation. There is a similar problem with the 32-bt atomic_dec_if_positive, that is implemented by ppc, mips, microblaze and avr32 but not in x86-32 and asm-generic. Currently the 64-bit version seems unused, while the 32-bit one seems to be only used by ppc-only drivers (IBM pSeries virtual SCSI and PlayStation3 drivers). I'll send a couple of patches to fix this shortly. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

Sent patches, both to conditionally perform the test and implement the functions for x86 and x86-64. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ |
