      Pull new zonefs file system from Damien Le Moal:
       "Zonefs is a very simple file system exposing each zone of a zoned
        block device as a file.
      
        Unlike a regular file system with native zoned block device support
        (e.g. f2fs or the on-going btrfs effort), zonefs does not hide the
        sequential write constraint of zoned block devices to the user. As a
        result, zonefs is not a POSIX compliant file system. Its goal is to
        simplify the implementation of zoned block devices support in
        applications by replacing raw block device file accesses with a richer
        file based API, avoiding relying on direct block device file ioctls
        which may be more obscure to developers.
      
        One example of this approach is the implementation of LSM
        (log-structured merge) tree structures (such as used in RocksDB and
        LevelDB) on zoned block devices by allowing SSTables to be stored in a
        zone file similarly to a regular file system rather than as a range of
        sectors of a zoned device. The introduction of the higher level
        construct "one file is one zone" can help reducing the amount of
        changes needed in the application while at the same time allowing the
        use of zoned block devices with various programming languages other
        than C.
      
        Zonefs IO management implementation uses the new iomap generic code.
        Zonefs has been successfully tested using a functional test suite
        (available with zonefs userland format tool on github) and a prototype
        implementation of LevelDB on top of zonefs"

      irqchip/gic-v4.1: Avoid 64bit division for the sake of 32bit ARM · 490d332e
      Marc Zyngier authored
      In order to allow the GICv4 code to link properly on 32bit ARM,
      make sure we don't use 64bit divisions when it isn't strictly
      necessary.

      Linus Torvalds authored
      Pull x86 fixes from Thomas Gleixner:
       "A set of fixes for X86:
      
         - Ensure that the PIT is set up when the local APIC is disable or
           configured in legacy mode. This is caused by an ordering issue
           introduced in the recent changes which skip PIT initialization when
           the TSC and APIC frequencies are already known.
      
         - Handle malformed SRAT tables during early ACPI parsing which caused
           an infinite loop anda boot hang.
      
         - Fix a long standing race in the affinity setting code which affects
           PCI devices with non-maskable MSI interrupts. The problem is caused
           by the non-atomic writes of the MSI address (destination APIC id)
           and data (vector) fields which the device uses to construct the MSI
           message. The non-atomic writes are mandated by PCI.
      
           If both fields change and the device raises an interrupt after
           writing address and before writing data, then the MSI block
           constructs a inconsistent message which causes interrupts to be
           lost and subsequent malfunction of the device.
      
           The fix is to redirect the interrupt to the new vector on the
           current CPU first and then switch it over to the new target CPU.
           This allows to observe an eventually raised interrupt in the
           transitional stage (old CPU, new vector) to be observed in the APIC
           IRR and retriggered on the new target CPU and the new vector.
      
           The potential spurious interrupts caused by this are harmless and
           can in the worst case expose a buggy driver (all handlers have to
           be able to deal with spurious interrupts as they can and do happen
           for various reasons).
      
         - Add the missing suspend/resume mechanism for the HYPERV hypercall
           page which prevents resume hibernation on HYPERV guests. This
           change got lost before the merge window.
      
         - Mask the IOAPIC before disabling the local APIC to prevent
           potentially stale IOAPIC remote IRR bits which cause stale
           interrupt lines after resume"
