This new version replaces existing userspace API with new easy-to-use and simple ones so we have already applied the use of these API to real user, Tizen Platform[1], and also makes existing Scaler, FIMC, GScaler and Rotator drivers to use IPP v2 core API.

2018-05-14drm/i915/execlists: Relax CSB force-mmio for VT-dChris Wilson
The original switch to use CSB from the HWSP was plagued by the effect of read ordering on VT-d; we would read the WRITE pointer from the HWSP before it had completed writing the CSB contents. The mystery comes down to the lack of rmb() for correct ordering with respect to the writes from HW, and with that resolved we can remove the VT-d special casing.

2018-05-12Revert "sched/numa: Delay retrying placement for automatic NUMA balance ↵Mel Gorman
after wake_affine()" This reverts commit 7347fc87dfe6b7315e74310ee1243dc222c68086. Srikar Dronamra pointed out that while the commit in question did show a performance improvement on ppc64, it did so at the cost of disabling active CPU migration by automatic NUMA balancing which was not the intent. The issue was that a serious flaw in the logic failed to ever active balance if SD_WAKE_AFFINE was disabled on scheduler domains. Even when it's enabled, the logic is still bizarre and against the original intent. Investigation showed that fixing the patch in either the way he suggested, using the correct comparison for jiffies values or introducing a new numa_migrate_deferred variable in task_struct all perform similarly to a revert with a mix of gains and losses depending on the workload, machine and socket count. The original intent of the commit was to handle a problem whereby wake_affine, idle balancing and automatic NUMA balancing disagree on the appropriate placement for a task. This was particularly true for cases where a single task was a massive waker of tasks but where wake_wide logic did not apply. This was particularly noticeable when a futex (a barrier) woke all worker threads and tried pulling the wakees to the waker nodes. In that specific case, it could be handled by tuning MPI or openMP appropriately, but the behavior is not illogical and was worth attempting to fix. However, the approach was wrong. Given that we're at rc4 and a fix is not obvious, it's better to play safe, revert this commit and retry later.

Since commit c1adf20052d8 ("Introduce rb_replace_node_rcu()") rbtree_augmented.h uses RCU related data structures but does not include the header file. It works as long as it gets somehow included before that and fails otherwise.

2018-05-11ocfs2: take inode cluster lock before moving reflinked inode from orphan dirAshish Samant
While reflinking an inode, we create a new inode in orphan directory, then take EX lock on it, reflink the original inode to orphan inode and release EX lock. Once the lock is released another node could request it in EX mode from ocfs2_recover_orphans() which causes downconvert of the lock, on this node, to NL mode. Later we attempt to initialize security acl for the orphan inode and move it to the reflink destination. However, while doing this we dont take EX lock on the inode. This could potentially cause problems because we could be starting transaction, accessing journal and modifying metadata of the inode while holding NL lock and with another node holding EX lock on the inode. Fix this by taking orphan inode cluster lock in EX mode before initializing security and moving orphan inode to reflink destination. Use the __tracker variant while taking inode lock to avoid recursive locking in the ocfs2_init_security_and_acl() call chain.

2018-05-11mm, oom: fix concurrent munlock and oom reaper unmap, v3David Rientjes
Since exit_mmap() is done without the protection of mm->mmap_sem, it is possible for the oom reaper to concurrently operate on an mm until MMF_OOM_SKIP is set. This allows munlock_vma_pages_all() to concurrently run while the oom reaper is operating on a vma. Since munlock_vma_pages_range() depends on clearing VM_LOCKED from vm_flags before actually doing the munlock to determine if any other vmas are locking the same memory, the check for VM_LOCKED in the oom reaper is racy. This is especially noticeable on architectures such as powerpc where clearing a huge pmd requires serialize_against_pte_lookup(). If the pmd is zapped by the oom reaper during follow_page_mask() after the check for pmd_none() is bypassed, this ends up deferencing a NULL ptl or a kernel oops. Fix this by manually freeing all possible memory from the mm before doing the munlock and then setting MMF_OOM_SKIP. The oom reaper can not run on the mm anymore so the munlock is safe to do in exit_mmap(). It also matches the logic that the oom reaper currently uses for determining when to set MMF_OOM_SKIP itself, so there's no new risk of excessive oom killing. This issue fixes CVE-2018-1000200.
