      mm: add missing __PAGETABLE_{PUD,PMD}_FOLDED defines · c07af4f1
      Kirill A. Shutemov authored
      Core mm expects __PAGETABLE_{PUD,PMD}_FOLDED to be defined if these page
      table levels folded.  Usually, these defines are provided by
      <asm-generic/pgtable-nopmd.h> and <asm-generic/pgtable-nopud.h>.
      
      But some architectures fold page table levels in a custom way.  They
      need to define these macros themself.  This patch adds missing defines.
      
      The patch fixes mm->nr_pmds underflow and eliminates dead __pmd_alloc()
      and __pud_alloc() on architectures without these page table levels.

      mm: page_alloc: revert inadvertent !__GFP_FS retry behavior change · cc873177
      Johannes Weiner authored
      Historically, !__GFP_FS allocations were not allowed to invoke the OOM
      killer once reclaim had failed, but nevertheless kept looping in the
      allocator.
      
      Commit 9879de73 ("mm: page_alloc: embed OOM killing naturally into
      allocation slowpath"), which should have been a simple cleanup patch,
      accidentally changed the behavior to aborting the allocation at that
      point.  This creates problems with filesystem callers (?) that currently
      rely on the allocator waiting for other tasks to intervene.
      
      Revert the behavior as it shouldn't have been changed as part of a
      cleanup patch.

      mm: memcontrol: use "max" instead of "infinity" in control knobs · d2973697
      Johannes Weiner authored
      The memcg control knobs indicate the highest possible value using the
      symbolic name "infinity", which is long and awkward to type.
      
      Switch to the string "max", which is just as descriptive but shorter and
      sweeter.
      
      This changes a user interface, so do it before the release and before
      the development flag is dropped from the default hierarchy.

      max_used_pages is defined as atomic_long_t so we need to use unsigned

      nilfs2: fix potential memory overrun on inode · 957ed60b
      Ryusuke Konishi authored
      Each inode of nilfs2 stores a root node of a b-tree, and it turned out to
      have a memory overrun issue:
      
      Each b-tree node of nilfs2 stores a set of key-value pairs and the number
      of them (in "bn_nchildren" member of nilfs_btree_node struct), as well as
      a few other "bn_*" members.
      
      Since the value of "bn_nchildren" is used for operations on the key-values
      within the b-tree node, it can cause memory access overrun if a large
      number is incorrectly set to "bn_nchildren".
      
      For instance, nilfs_btree_node_lookup() function determines the range of
      binary search with it, and too large "bn_nchildren" leads
      nilfs_btree_node_get_key() in that function to overrun.
      
      As for intermediate b-tree nodes, this is prevented by a sanity check
      performed when each node is read from a drive, however, no sanity check
      has been done for root nodes stored in inodes.
      
      This patch fixes the issue by adding missing sanity check against b-tree
      root nodes so that it's called when on-memory inodes are read from ifile,
      inode metadata file.

      Arnd Bergmann authored
      The newly added ds1685 driver causes a build error when enabled without

        drivers/rtc/rtc-ds1685.c:919:22: error: 'ds1685_rtc_alarm_irq_enable' undeclared here (not in a function)
          .alarm_irq_enable = ds1685_rtc_alarm_irq_enable,
      
      Apparently the driver was incorrectly changed to reflect the interface
      change from 16380c15 ("RTC: Convert rtc drivers to use the
      alarm_irq_enable method"), which removed the respective #ifdef from all
      other rtc drivers.
      
      This does the same change that was merged for the other drivers before and
      removes the #ifdef, allowing the interrupts to be enabled through the
      in-kernel rtc interface independent of the existence of /dev/rtc.

      memcg: fix low limit calculation · 4e54dede
      Michal Hocko authored
      A memcg is considered low limited even when the current usage is equal to
      the low limit.  This leads to interesting side effects e.g.
      groups/hierarchies with no memory accounted are considered protected and
      so the reclaim will emit MEMCG_LOW event when encountering them.
      
      Another and much bigger issue was reported by Joonsoo Kim.  He has hit a
      NULL ptr dereference with the legacy cgroup API which even doesn't have
      low limit exposed.  The limit is 0 by default but the initial check fails
      for memcg with 0 consumption and parent_mem_cgroup() would return NULL if
      use_hierarchy is 0 and so page_counter_read would try to dereference NULL.
      
      I suppose that the current implementation is just an overlook because the
      documentation in Documentation/cgroups/unified-hierarchy.txt says:
      
        "The memory.low boundary on the other hand is a top-down allocated
        reserve.  A cgroup enjoys reclaim protection when it and all its
        ancestors are below their low boundaries"
      
      Fix the usage and the low limit comparision in mem_cgroup_low accordingly.

        Unable to allocate RAM for process text/data, errno 12 SEGV
      
      This problem happens because we allocate ordered page through
      __get_free_pages() in do_mmap_private() in some cases and we try to free
      individual pages rather than ordered page in free_page_series().  In
      this case, freeing pages whose refcount is not 0 won't be freed to the
      page allocator so memory leak happens.
      
      To fix the problem, this patch changes __get_free_pages() to
      alloc_pages_exact() since alloc_pages_exact() returns
      physically-contiguous pages but each pages are refcounted.
      
      Fixes: dbc8358c ("mm/nommu: use alloc_pages_exact() rather than its own implementation").

      ocfs2: update web page + git tree in documentation · 01945fa2
      Mark Fasheh authored
      We (the Ocfs2 project) recently moved the location of our ocfs2-tools
      git tree and project web page.  The pertinent discussion can be seen
      here:
      
        https://oss.oracle.com/pipermail/ocfs2-devel/2015-February/010579.html
      
      The following patch updates the Ocfs2 documentation in MAINTAINERS,
      ocfs2.txt, and dlmfs.txt.  I added our new official web page, changed
      the location of our tools git tree and removed the link to Joel's
      ancient kernel git tree - Andrew has handled our patches for a while
      now.

      x86: Init per-cpu shadow copy of CR4 on 32-bit CPUs too · 5b2bdbc8
      Steven Rostedt authored
      Commit:
      
         1e02ce4c ("x86: Store a per-cpu shadow copy of CR4")
      
      added a shadow CR4 such that reads and writes that do not
      modify the CR4 execute much faster than always reading the
      register itself.
      
      The change modified cpu_init() in common.c, so that the
      shadow CR4 gets initialized before anything uses it.
      
      Unfortunately, there's two cpu_init()s in common.c. There's
      one for 64-bit and one for 32-bit. The commit only added
      the shadow init to the 64-bit path, but the 32-bit path
      needs the init too.
