      Fix kmalloc slab creation sequence · a9730fca
      Christoph Lameter authored
      This patch restores the slab creation sequence that was broken by commit
      4066c33d and also reverts the portions that introduced the
      KMALLOC_LOOP_XXX macros. Those can never really work since the slab creation
      is much more complex than just going from a minimum to a maximum number.
      
      The latest upstream kernel boots cleanly on my machine with a 64 bit x86
      configuration under KVM using either SLAB or SLUB.
      
      Fixes: 4066c33d ("support the slub_debug boot option")

      Merge tag 'libnvdimm-for-4.2' of git://git.kernel.org/pub/scm/linux/kernel/git/djbw/nvdimm · 88793e5c
      Linus Torvalds authored
      Pull libnvdimm subsystem from Dan Williams:
       "The libnvdimm sub-system introduces, in addition to the
        libnvdimm-core, 4 drivers / enabling modules:
      
        NFIT:
          Instantiates an "nvdimm bus" with the core and registers memory
          devices (NVDIMMs) enumerated by the ACPI 6.0 NFIT (NVDIMM Firmware
          Interface table).
      
          After registering NVDIMMs the NFIT driver then registers "region"
          devices.  A libnvdimm-region defines an access mode and the
          boundaries of persistent memory media.  A region may span multiple
          NVDIMMs that are interleaved by the hardware memory controller.  In
          turn, a libnvdimm-region can be carved into a "namespace" device and
          bound to the PMEM or BLK driver which will attach a Linux block
          device (disk) interface to the memory.
      
        PMEM:
          Initially merged in v4.1 this driver for contiguous spans of
          persistent memory address ranges is re-worked to drive
          PMEM-namespaces emitted by the libnvdimm-core.
      
          In this update the PMEM driver, on x86, gains the ability to assert
          that writes to persistent memory have been flushed all the way
          through the caches and buffers in the platform to persistent media.
          See memcpy_to_pmem() and wmb_pmem().
      
        BLK:
          This new driver enables access to persistent memory media through
          "Block Data Windows" as defined by the NFIT.  The primary difference
          of this driver to PMEM is that only a small window of persistent
          memory is mapped into system address space at any given point in
          time.
      
          Per-NVDIMM windows are reprogrammed at run time, per-I/O, to access
          different portions of the media.  BLK-mode, by definition, does not
          support DAX.
      
        BTT:
          This is a library, optionally consumed by either PMEM or BLK, that
          converts a byte-accessible namespace into a disk with atomic sector
          update semantics (prevents sector tearing on crash or power loss).
      
          The sinister aspect of sector tearing is that most applications do
          not know they have a atomic sector dependency.  At least today's
          disk's rarely ever tear sectors and if they do one almost certainly
          gets a CRC error on access.  NVDIMMs will always tear and always
          silently.  Until an application is audited to be robust in the
          presence of sector-tearing the usage of BTT is recommended.

      Pull GFS2 updates from Bob Peterson:
       "Here are the patches we've accumulated for GFS2 for the current
        upstream merge window.  We have a good mixture this time.  Here are
        some of the features:
      
         - Fix a problem with RO mounts writing to the journal.
      
         - Further improvements to quotas on GFS2.
      
         - Added support for rename2 and RENAME_EXCHANGE on GFS2.
      
         - Increase performance by making glock lru_list less of a bottleneck.
      
         - Increase performance by avoiding unnecessary buffer_head releases.
      
         - Increase performance by using average glock round trip time from all CPUs.
      
         - Fixes for some compiler warnings and minor white space issues.
      
         - Other misc bug fixes"

      Pull cgroup updates from Tejun Heo:
      
       - threadgroup_lock got reorganized so that its users can pick the
         actual locking mechanism to use.  Its only user - cgroups - is
         updated to use a percpu_rwsem instead of per-process rwsem.
      
         This makes things a bit lighter on hot paths and allows cgroups to
         perform and fail multi-task (a process) migrations atomically.
         Multi-task migrations are used in several places including the
         unified hierarchy.
      
       - Delegation rule and documentation added to unified hierarchy.  This
         will likely be the last interface update from the cgroup core side
         for unified hierarchy before lifting the devel mask.
      
       - Some groundwork for the pids controller which is scheduled to be
         merged in the coming devel cycle.
      
      * 'for-4.2' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup:
        cgroup: add delegation section to unified hierarchy documentation
        cgroup: require write perm on common ancestor when moving processes on the default hierarchy
        cgroup: separate out cgroup_procs_write_permission() from __cgroup_procs_write()
        kernfs: make kernfs_get_inode() public
        MAINTAINERS: add a cgroup core co-maintainer
        cgroup: fix uninitialised iterator in for_each_subsys_which
        cgroup: replace explicit ss_mask checking with for_each_subsys_which
        cgroup: use bitmask to filter for_each_subsys

        cgroup: simplify threadgroup locking
        sched, cgroup: replace signal_struct->group_rwsem with a global percpu_rwsem
        sched, cgroup: reorganize threadgroup locking
        cgroup: switch to unsigned long for bitmasks
        cgroup: reorganize include/linux/cgroup.h
