Subject[PATCH -v10 0/4] Lock-less list
Date
v10:

- Rebased on latest Linus' tree.
- Revise ARCH_HAVE_NMI_SAFE_CMPXCHG definition for SPARC32 per arch
maintainer's comments.

v9:

- Split out lock-less allocator, will repost allocator with its user
in another patchset.
- Use lock-less list in irq_work and replace net/rds/xlist.h

v8:

- Rebased on mmotm 2010-12-02

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.

- Revise ARCH_HAVE_NMI_SAFE_CMPXCHG definition for some architectures
according to architecture maitainers' comments.

v5:

- Add ARCH_HAVE_NMI_SAFE_CMPXCHG

if ARCH_HAVE_NMI_SAFE_CMPXCHG=n
- Make lockless list depends on ARCH_HAVE_NMI_SAFE_CMPXCHG

- Split from APEI patchset
- Update patch description and comments according to ML comments
