      x86: remove the kernel code/data/bss resources from /proc/iomem · c4004b02
      Linus Torvalds authored
      Let's see if anybody even notices.  I doubt anybody uses this, and it
      does expose addresses that should be randomized, so let's just remove
      the code.  It's old and traditional, and it used to be cute, but we
      should have removed this long ago.
      If it turns out anybody notices and this breaks something, we'll have to
      revert this, and maybe we'll end up using other approaches instead
      (using %pK or similar).  But removing unnecessary code is always the
      preferred option.

      i40iw: avoid potential uninitialized variable use · 2fe78571
      Arnd Bergmann authored
      gcc finds that the i40iw_make_cm_node() function in the recently added
      i40iw driver uses an uninitilized variable as an index into an array
      if CONFIG_IPV6 is disabled and the driver uses IPv6 mode:
      drivers/infiniband/hw/i40iw/i40iw_cm.c: In function 'i40iw_make_cm_node':
      drivers/infiniband/hw/i40iw/i40iw_cm.c:2206:52: error: 'arpindex' may be used uninitialized in this function [-Werror=maybe-uninitialized]
        ether_addr_copy(cm_node->rem_mac, iwdev->arp_table[arpindex].mac_addr);
      As far as I can tell, this code path can not be used because the ipv4
      variable is always set with CONFIG_IPV6 is disabled, but it's better
      to be sure and prevent the undefined behavior, as well as shut up
      that warning in a proper way.
      This adds an 'else' clause for the case we get the warning about,
      causing the function to return an error in a controlled way.
      To avoid adding extra mess with combined io()/#ifdef clauses,
      I'm also converting the existing #ifdef into a more readable
      if(IS_ENABLED()) check.

      Arnd Bergmann authored
      The previous patch that added a couple of callback functions put
      the declarations inside of an #ifdef CONFIG_INFINIBAND_ON_DEMAND_PAGING,

      rbd: use GFP_NOIO consistently for request allocations · 2224d879
      David Disseldorp authored
      As of 5a60e876
      , RBD object request
      allocations are made via rbd_obj_request_create() with GFP_NOIO.
      However, subsequent OSD request allocations in rbd_osd_req_create*()
      use GFP_ATOMIC.
      With heavy page cache usage (e.g. OSDs running on same host as krbd
      client), rbd_osd_req_create() order-1 GFP_ATOMIC allocations have been
      observed to fail, where direct reclaim would have allowed GFP_NOIO
      allocations to succeed.

      kvm: x86: make lapic hrtimer pinned · 61abdbe0
      Luiz Capitulino authored
      When a vCPU runs on a nohz_full core, the hrtimer used by
      the lapic emulation code can be migrated to another core.
      When this happens, it's possible to observe milisecond
      latency when delivering timer IRQs to KVM guests.
      The huge latency is mainly due to the fact that
      apic_timer_fn() expects to run during a kvm exit. It
      sets KVM_REQ_PENDING_TIMER and let it be handled on kvm
      entry. However, if the timer fires on a different core,
      we have to wait until the next kvm exit for the guest
      to see KVM_REQ_PENDING_TIMER set.
      This problem became visible after commit 9642d18e
      . This
      commit changed the timer migration code to always attempt
      to migrate timers away from nohz_full cores. While it's
      discussable if this is correct/desirable (I don't think
      it is), it's clear that the lapic emulation code has
      a requirement on firing the hrtimer in the same core
      where it was started. This is achieved by making the
      hrtimer pinned.
      Lastly, note that KVM has code to migrate timers when a
      vCPU is scheduled to run in different core. However, this
      forced migration may fail. When this happens, we can have
      the same problem. If we want 100% correctness, we'll have
      to modify apic_timer_fn() to cause a kvm exit when it runs
      on a different core than the vCPU. Not sure if this is
      Here's a reproducer for the issue being fixed:
       1. Set all cores but core0 to be nohz_full cores
       2. Start a guest with a single vCPU
       3. Trace apic_timer_fn() and kvm_inject_apic_timer_irqs()
      You'll see that apic_timer_fn() will run in core0 while
      kvm_inject_apic_timer_irqs() runs in a different core. If
      you get both on core0, try running a program that takes 100%
      of the CPU and pin it to core0 to force the vCPU out.
