      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"

      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 ("ACPI/IORT: Support address size limit for root complexes")

      i2c: dev: prevent adapter retries and timeout being set as minus value · 6ebec961
      Yi Zeng authored
      If adapter->retries is set to a minus value from user space via ioctl,
      it will make __i2c_transfer and __i2c_smbus_xfer skip the calling to
      adapter->algo->master_xfer and adapter->algo->smbus_xfer that is
      registered by the underlying bus drivers, and return value 0 to all the
      callers. The bus driver will never be accessed anymore by all users,
      besides, the users may still get successful return value without any
      error or information log print out.
      
      If adapter->timeout is set to minus value from user space via ioctl,
      it will make the retrying loop in __i2c_transfer and __i2c_smbus_xfer
      always break after the the first try, due to the time_after always
      returns true.

         - 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.

      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
