Merge branch 'akpm-incoming-2'
* akpm-incoming-2: (139 commits) epoll: make epoll_wait() use the hrtimer range feature select: rename estimate_accuracy() to select_estimate_accuracy() Remove duplicate includes from many files ramoops: use the platform data structure instead of module params kernel/resource.c: handle reinsertion of an already-inserted resource kfifo: fix kfifo_alloc() to return a signed int value w1: don't allow arbitrary users to remove w1 devices alpha: remove dma64_addr_t usage mips: remove dma64_addr_t usage sparc: remove dma64_addr_t usage fuse: use release_pages() taskstats: use real microsecond granularity for CPU times taskstats: split fill_pid function taskstats: separate taskstats commands delayacct: align to 8 byte boundary on 64-bit systems delay-accounting: reimplement -c for getdelays.c to report information on a target command namespaces Kconfig: move namespace menu location after the cgroup namespaces Kconfig: remove the cgroup device whitelist experimental tag namespaces Kconfig: remove pointless cgroup dependency namespaces Kconfig: make namespace a submenu ...
