      scripts/dtc: Remove redundant YYLOC global declaration · e33a814e
      Dirk Mueller authored
      gcc 10 will default to -fno-common, which causes this error at link
        (.text+0x0): multiple definition of `yylloc'; dtc-lexer.lex.o (symbol from plugin):(.text+0x0): first defined here
      This is because both dtc-lexer as well as dtc-parser define the same
      global symbol yyloc. Before with -fcommon those were merged into one
      defintion. The proper solution would be to to mark this as "extern",
      however that leads to:
        dtc-lexer.l:26:16: error: redundant redeclaration of 'yylloc' [-Werror=redundant-decls]

      Linus Torvalds authored
      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"

      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"

      Apparently this didn't get any build testing anywhere.  Not perhaps all
      that surprising: it's restricted to 64-bit MIPS only, and only with the
      new SGI_MFD_IOC3 support enabled.
      I only noticed because the ioremap conflicts in the ARM SoC driver
      update made me check there weren't any others hiding, and I found this

       "This is some material that we picked up into our tree late, or that
        had more complex dependencies on more than one topic branch that makes
        sense to keep separately.
         - TI support for secure accelerators and hwrng on OMAP4/5
         - TI camera changes for dra7 and am437x and SGX improvement due to
           better reset control support on am335x, am437x and dra7
         - Davinci moves to proper clocksource on DM365, and regulator/audio
           improvements for DM365 and DM644x eval boards"

       "We keep this in a separate branch to avoid cross-branch conflicts, but
        most of the material here is fairly boring -- some new drivers turned
        on for hardware since they were merged, and some refreshed files due
        to time having moved a lot of entries around"
