      That should make user space bugs more obvious.

      amdgpu: fix NULL pointer dereference at tonga_check_states_equal · 827108d0
      Bradley Pankow authored
      The event_data passed from pem_fini was not cleared upon initialization.
      This caused NULL checks to pass and cast_const_phw_tonga_power_state to
      attempt to dereference an invalid pointer. Clear the event_data in
      pem_init and pem_fini before calling pem_handle_event.

        This leak does not happen if blk-mq DM multipath is used.  It only
        occurs if .request_fn DM multipath is stacked ontop of blk-mq paths

      x86: fix SMAP in 32-bit environments · de9e478b
      Linus Torvalds authored
      In commit 11f1a4b9 ("x86: reorganize SMAP handling in user space
      accesses") I changed how the stac/clac instructions were generated
      around the user space accesses, which then made it possible to do
      batched accesses efficiently for user string copies etc.
      
      However, in doing so, I completely spaced out, and didn't even think
      about the 32-bit case.  And nobody really even seemed to notice, because
      SMAP doesn't even exist until modern Skylake processors, and you'd have
      to be crazy to run 32-bit kernels on a modern CPU.
      
      Which brings us to Andy Lutomirski.
      
      He actually tested the 32-bit kernel on new hardware, and noticed that
      it doesn't work.  My bad.  The trivial fix is to add the required
      uaccess begin/end markers around the raw accesses in <asm/uaccess_32.h>.
      
      I feel a bit bad about this patch, just because that header file really
      should be cleaned up to avoid all the duplicated code in it, and this
      commit just expands on the problem.  But this just fixes the bug without
      any bigger cleanup surgery.
