git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu into core/urgent Pull two RCU fixes from Paul E. McKenney: " - Complete the work of commit dd56af42bd82 (rcu: Eliminate deadlock between CPU hotplug and expedited grace periods), which was intended to allow synchronize_sched_expedited() to be safely used when holding locks acquired by CPU-hotplug notifiers. This commit makes the put_online_cpus() avoid the deadlock instead of just handling the get_online_cpus(). - Complete the work of commit 35ce7f29a44a (rcu: Create rcuo kthreads only for onlined CPUs), which was intended to allow RCU to avoid allocating unneeded kthreads on systems where the firmware says that there are more CPUs than are really present. This commit makes rcu_barrier() aware of the mismatch, so that it doesn't hang waiting for non-existent CPUs. " Signed-off-by: Ingo Molnar <mingo@kernel.org>

2014-10-29mm: memcontrol: fix missed end-writeback page accountingJohannes Weiner
Commit 0a31bc97c80c ("mm: memcontrol: rewrite uncharge API") changed page migration to uncharge the old page right away. The page is locked, unmapped, truncated, and off the LRU, but it could race with writeback ending, which then doesn't unaccount the page properly: test_clear_page_writeback() migration wait_on_page_writeback() TestClearPageWriteback() mem_cgroup_migrate() clear PCG_USED mem_cgroup_update_page_stat() if (PageCgroupUsed(pc)) decrease memcg pages under writeback release pc->mem_cgroup->move_lock The per-page statistics interface is heavily optimized to avoid a function call and a lookup_page_cgroup() in the file unmap fast path, which means it doesn't verify whether a page is still charged before clearing PageWriteback() and it has to do it in the stat update later. Rework it so that it looks up the page's memcg once at the beginning of the transaction and then uses it throughout. The charge will be verified before clearing PageWriteback() and migration can't uncharge the page as long as that is still set. The RCU lock will protect the memcg past uncharge. As far as losing the optimization goes, the following test results are from a microbenchmark that maps, faults, and unmaps a 4GB sparse file three times in a nested fashion, so that there are two negative passes that don't account but still go through the new transaction overhead. There is no actual difference: old: 33.195102545 seconds time elapsed ( +- 0.01% ) new: 33.199231369 seconds time elapsed ( +- 0.03% ) The time spent in page_remove_rmap()'s callees still adds up to the same, but the time spent in the function itself seems reduced: # Children Self Command Shared Object Symbol old: 0.12% 0.11% filemapstress [kernel.kallsyms] [k] page_remove_rmap new: 0.12% 0.08% filemapstress [kernel.kallsyms] [k] page_remove_rmap Signed-off-by: Johannes Weiner <hannes@cmpxchg.org> Acked-by: Michal Hocko <mhocko@suse.cz> Cc: Vladimir Davydov <vdavydov@parallels.com> Cc: <stable@vger.kernel.org> [3.17.x] Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2014-10-29mm, thp: fix collapsing of hugepages on madviseDavid Rientjes
If an anonymous mapping is not allowed to fault thp memory and then madvise(MADV_HUGEPAGE) is used after fault, khugepaged will never collapse this memory into thp memory. This occurs because the madvise(2) handler for thp, hugepage_madvise(), clears VM_NOHUGEPAGE on the stack and it isn't stored in vma->vm_flags until the final action of madvise_behavior(). This causes the khugepaged_enter_vma_merge() to be a no-op in hugepage_madvise() when the vma had previously had VM_NOHUGEPAGE set. Fix this by passing the correct vma flags to the khugepaged mm slot handler. There's no chance khugepaged can run on this vma until after madvise_behavior() returns since we hold mm->mmap_sem. It would be possible to clear VM_NOHUGEPAGE directly from vma->vm_flags in hugepage_advise(), but I didn't want to introduce special case behavior into madvise_behavior(). I think it's best to just let it always set vma->vm_flags itself. Signed-off-by: David Rientjes <rientjes@google.com> Reported-by: Suleiman Souhlal <suleiman@google.com> Cc: "Kirill A.

2014-10-29net: ipv6: Add a sysctl to make optimistic addresses useful candidatesErik Kline
Add a sysctl that causes an interface's optimistic addresses to be considered equivalent to other non-deprecated addresses for source address selection purposes. Preferred addresses will still take precedence over optimistic addresses, subject to other ranking in the source address selection algorithm. This is useful where different interfaces are connected to different networks from different ISPs (e.g., a cell network and a home wifi network). The current behaviour complies with RFC 3484/6724, and it makes sense if the host has only one interface, or has multiple interfaces on the same network (same or cooperating administrative domain(s), but not in the multiple distinct networks case. For example, if a mobile device has an IPv6 address on an LTE network and then connects to IPv6-enabled wifi, while the wifi IPv6 address is undergoing DAD, IPv6 connections will try use the wifi default route with the LTE IPv6 address, and will get stuck until they time out. Also, because optimistic nodes can receive frames, issue an RTM_NEWADDR as soon as DAD starts (with the IFA_F_OPTIMSTIC flag appropriately set). A second RTM_NEWADDR is sent if DAD completes (the address flags have changed), otherwise an RTM_DELADDR is sent. Also: add an entry in ip-sysctl.txt for optimistic_dad.

2014-10-29blk-mq: add a 'list' parameter to ->queue_rq()Jens Axboe
Since we have the notion of a 'last' request in a chain, we can use this to have the hardware optimize the issuing of requests. Add a list_head parameter to queue_rq that the driver can use to temporarily store hw commands for issue when 'last' is true. If we are doing a chain of requests, pass in a NULL list for the first request to force issue of that immediately, then batch the remainder for deferred issue until the last request has been sent. Instead of adding yet another argument to the hot ->queue_rq path, encapsulate the passed arguments in a blk_mq_queue_data structure. This is passed as a constant, and has been tested as faster than passing 4 (or even 3) args through ->queue_rq. Update drivers for the new ->queue_rq() prototype. There are no functional changes in this patch for drivers - if they don't use the passed in list, then they will just queue requests individually like before. Signed-off-by: Jens Axboe <axboe@fb.com>

CLOCK_REALTIME ktime_get_real_seconds() is the replacement function for get_seconds() returning the seconds portion of CLOCK_REALTIME in a time64_t. For 64bit the function is equivivalent to get_seconds(), but for 32bit it protects the readout with the timekeeper sequence count. This is required because 32-bit machines cannot access 64-bit tk->xtime_sec variable atomically.

2014-10-29timekeeping: Provide fast accessor to the seconds part of CLOCK_MONOTONICHeena Sirwani
This is the counterpart to get_seconds() based on CLOCK_MONOTONIC. The use case for this interface are kernel internal coarse grained timestamps which do neither require the nanoseconds fraction of current time nor the CLOCK_REALTIME properties. Such timestamps can currently only retrieved by calling ktime_get_ts64() and using the tv_sec field of the returned timespec64. That's inefficient as it involves the read of the clocksource, math operations and must be protected by the timekeeper sequence counter. To avoid the sequence counter protection we restrict the return value to unsigned 32bit on 32bit machines. This covers ~136 years of uptime and therefor an overflow is not expected to hit anytime soon. To avoid math in the function we calculate the current seconds portion of CLOCK_MONOTONIC when the timekeeper gets updated in tk_update_ktime_data() similar to the CLOCK_REALTIME counterpart xtime_sec.

2014-10-28rcu: Provide counterpart to rcu_dereference() for non-RCU situationsPaul E. McKenney
Although rcu_dereference() and friends can be used in situations where object lifetimes are being managed by something other than RCU, the resulting sparse and lockdep-RCU noise can be annoying. This commit therefore supplies a lockless_dereference(), which provides the protection for dereferences without the RCU-related debugging noise.
