Here comes a set of 4 patches which build on top of your work by: 1) Killing quicklists on sparc64 2) Using the generic RCU page table liberation code on sparc64 3) Implement pte_special() et al. on sparc64 4) Implement get_user_pages_fast() on sparc64 Please add them to your patch set. If you change the RCU generic code enabler CPP define to be controlled via Kconfig (as we discussed on IRC) it should be easy to propagate that change into patch #2 here. Thanks!
