This patchset adds a lockless memory allocator and a lock-less list. v7: - Revise ARCH_HAVE_NMI_SAFE_CMPXCHG definition for some architectures according to architecture maitainers' comments. - Remove spin_trylock_irqsave based fallback for lockless memory allocator, because it does not work for !CONFIG_SMP and is not likely to be used. - Make lockless memory allocator and list does not depend on ARCH_HAVE_NMI_SAFE_CMPXCHG. Instead, require the user to depend on it when needed. And BUG_ON(in_nmi()) is added in necessary place to prevent silent race. v6: - Revise ARCH_HAVE_NMI_SAFE_CMPXCHG definition for some architectures according to architecture maitainers' comments. v5: - Add ARCH_HAVE_NMI_SAFE_CMPXCHG - Add spin_trylock_irqsave based fallback in lockless memory allocator if ARCH_HAVE_NMI_SAFE_CMPXCHG=n - Make lockless list depends on ARCH_HAVE_NMI_SAFE_CMPXCHG v4: - Split from APEI patchset - Update patch description and comments according to ML comments v3: - Rework lockless memory allocator and list according to ML comments [PATCH -v7 1/3] Add Kconfig option ARCH_HAVE_NMI_SAFE_CMPXCHG [PATCH -v7 2/3] lib, Make gen_pool memory allocator lockless [PATCH -v7 3/3] lib, Add lock-less NULL terminated single list -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
