      IB/core: added support to use rdma cgroup controller · 43579b5f
      Parav Pandit authored
      Added support APIs for IB core to register/unregister every IB/RDMA
      device with rdma cgroup for tracking rdma resources.
      IB core registers with rdma cgroup controller.
      Added support APIs for uverbs layer to make use of rdma controller.
      Added uverbs layer to perform resource charge/uncharge functionality.
      Added support during query_device uverb operation to ensure it
      returns resource limits by honoring rdma cgroup configured limits.

      rdmacg: Added rdma cgroup controller · 39d3e758
      Parav Pandit authored
      Added rdma cgroup controller that does accounting, limit enforcement
      on rdma/IB resources.
      
      Added rdma cgroup header file which defines its APIs to perform
      charging/uncharging functionality. It also defined APIs for RDMA/IB
      stack for device registration. Devices which are registered will
      participate in controller functions of accounting and limit
      enforcements. It define rdmacg_device structure to bind IB stack
      and RDMA cgroup controller.
      
      RDMA resources are tracked using resource pool. Resource pool is per
      device, per cgroup entity which allows setting up accounting limits
      on per device basis.
      
      Currently resources are defined by the RDMA cgroup.
      
      Resource pool is created/destroyed dynamically whenever
      charging/uncharging occurs respectively and whenever user
      configuration is done. Its a tradeoff of memory vs little more code
      space that creates resource pool object whenever necessary, instead of
      creating them during cgroup creation and device registration time.

      powerpc: Fix build warning on 32-bit PPC · 8ae679c4
      Larry Finger authored
      I am getting the following warning when I build kernel 4.9-git on my
      PowerBook G4 with a 32-bit PPC processor:
      
          AS      arch/powerpc/kernel/misc_32.o
        arch/powerpc/kernel/misc_32.S:299:7: warning: "CONFIG_FSL_BOOKE" is not defined [-Wundef]
      
      This problem is evident after commit 989cea5c ("kbuild: prevent
      lib-ksyms.o rebuilds"); however, this change in kbuild only exposes an
      error that has been in the code since 2005 when this source file was
      created.  That was with commit 9994a338 ("powerpc: Introduce
      entry_{32,64}.S, misc_{32,64}.S, systbl.S").
      
      The offending line does not make a lot of sense.  This error does not
      seem to cause any errors in the executable, thus I am not recommending
      that it be applied to any stable versions.
      
      Thanks to Nicholas Piggin for suggesting this solution.
      
      Fixes: 9994a338 ("powerpc: Introduce entry_{32,64}.S, misc_{32,64}.S, systbl.S")
