      Pull arm64 fixes from Will Deacon:
       "Another handful of arm64 fixes here. Most of the complication comes
        from improving our kpti code to avoid lengthy pauses (30+ seconds)
        during boot when we rewrite the page tables. There are also a couple
        of IORT fixes that came in via Lorenzo.
      
        Summary:
      
         - Don't error in kexec_file_load if kaslr-seed is missing in
           device-tree
      
         - Fix incorrect argument type passed to iort_match_node_callback()
      
         - Fix IORT build failure when CONFIG_IOMMU_API=n
      
         - Fix kpti performance regression with new rodata default option
      
         - Typo fix"

           for arch_set_freq_scale() and make the scale-invariant load
           tracking acutally work with this driver (Quentin Perret).
      
         - Fix freeing of dynamic OPPs in the SCPI and SCMI cpufreq drivers
           broken during the 4.20 defelopment cycle (Viresh Kumar).
      
         - Prevent the cpufreq core from attempting to return the current
           frequency of offline CPUs (Sudeep Holla).
      
         - Add devfreq suspend and resume hooks (missed previously) to the PM
           core to make the recently added system suspend and resume support
           in devfreq actually work (Lukasz Luba).

           references to new/current documentation to them (Rafael Wysocki).

      arm64: kexec_file: return successfully even if kaslr-seed doesn't exist · 27966721
      AKASHI Takahiro authored
      In kexec_file_load, kaslr-seed property of the current dtb will be deleted
      any way before setting a new value if possible. It doesn't matter whether
      it exists in the current dtb.
      
      So "ret" should be reset to 0 here.

      ACPI/IORT: Fix rc_dma_get_range() · c7777236
      Jean-Philippe Brucker authored
      When executed for a PCI_ROOT_COMPLEX type, iort_match_node_callback()
      expects the opaque pointer argument to be a PCI bus device. At the
      moment rc_dma_get_range() passes the PCI endpoint instead of the bus,
      and we've been lucky to have pci_domain_nr(ptr) return 0 instead of
      crashing. Pass the bus device to iort_scan_node().
      
      Fixes: 5ac65e8c

      Pull RISC-V updates from Palmer Dabbelt:
       "This tag contains a handful of updates that slipped through the cracks
        during the merge window due to the holidays. The fixes are mostly
        independent, with the exception of one larger audit-related branch.
      
        Core RISC-V updates:
      
         - The BSS has been moved, which shrinks flat images.
      
         - A fix to test-bpf so it compiles on RV64I-based systems.
      
         - A fix to respect the kernel commandline when there is no device
           tree.
      
         - A fix to prevent CPUs from trying to put themselves to sleep when
           bringing down the system.
      
         - Support for MODULE_SECTIONS on RV32I-based systems.
      
         - [new in v2] The addition of an SBI earlycon driver. This is
           definately a new feature, but I'd like to include it now because I
           dropped this patch when submitting the merge window PR that removed
           our EARLY_PRINTK support.
      
        RISC-V audit updates:
      
         - The addition of NR_syscalls into unistd.h, which is necessary for
           CONFIG_FTRACE_SYSCALLS.
      
         - The definition of CREATE_TRACE_POINTS so __tracepoint_sys_{enter,exit}
           get defined.
      
         - A fix for trace_sys_exit() so we can enable HAVE_SYSCALL_TRACEPOINTS
      
        As usual, I've tested this by booting a Fedora-based image on a recent
        QEMU (this time just whatever I had lying around).

      arm64: kpti: Avoid rewriting early page tables when KASLR is enabled · b89d82ef
      Will Deacon authored
      A side effect of commit c55191e9
      
       ("arm64: mm: apply r/o permissions
      of VM areas to its linear alias as well") is that the linear map is
      created with page granularity, which means that transitioning the early
      page table from global to non-global mappings when enabling kpti can
      take a significant amount of time during boot.
      
      Given that most CPU implementations do not require kpti, this mainly
      impacts KASLR builds where kpti is forcefully enabled. However, in these
      situations we know early on that non-global mappings are required and
      can avoid the use of global mappings from the beginning. The only gotcha
      is Cavium erratum #27456, which we must detect based on the MIDR value
      of the boot CPU.

      mm/mmu_notifier: mm/rmap.c: Fix a mmu_notifier range bug in try_to_unmap_one · ba422731
      Sean Christopherson authored
      
      
      The conversion to use a structure for mmu_notifier_invalidate_range_*()
      unintentionally changed the usage in try_to_unmap_one() to init the
      'struct mmu_notifier_range' with vma->vm_start instead of @address,
      i.e. it invalidates the wrong address range.  Revert to the correct
      address range.
      
      Manifests as KVM use-after-free WARNINGs and subsequent "BUG: Bad page
      state in process X" errors when reclaiming from a KVM guest due to KVM
      removing the wrong pages from its own mappings.

      rbd: don't return 0 on unmap if RBD_DEV_FLAG_REMOVING is set · 85f5a4d6
      Ilya Dryomov authored
      
      
      There is a window between when RBD_DEV_FLAG_REMOVING is set and when
      the device is removed from rbd_dev_list.  During this window, we set
      "already" and return 0.
      
      Returning 0 from write(2) can confuse userspace tools because
      0 indicates that nothing was written.  In particular, "rbd unmap"
      will retry the write multiple times a second:
      
        10:28:05.463299 write(4, "0", 1)        = 0
        10:28:05.463509 write(4, "0", 1)        = 0
        10:28:05.463720 write(4, "0", 1)        = 0
        10:28:05.463942 write(4, "0", 1)        = 0
