      Pull core signal handling updates from Eric Biederman:
       "It was observed that a periodic timer in combination with a
        sufficiently expensive fork could prevent fork from every completing.
        This contains the changes to remove the need for that restart.
      
        This set of changes is split into several parts:
      
         - The first part makes PIDTYPE_TGID a proper pid type instead
           something only for very special cases. The part starts using
           PIDTYPE_TGID enough so that in __send_signal where signals are
           actually delivered we know if the signal is being sent to a a group
           of processes or just a single process.
      
         - With that prep work out of the way the logic in fork is modified so
           that fork logically makes signals received while it is running
           appear to be received after the fork completes"

      microblaze/PCI: Remove stale pcibios_align_resource() comment · c4347b05
      Lorenzo Pieralisi authored
      commit 01cf9d52 ("microblaze/PCI: Support generic Xilinx AXI PCIe Host
      Bridge IP driver")
      
      and
      
      commit ecf677c8 ("PCI: Add a generic weak pcibios_align_resource()")
      
      first patched then removed pcibios_align_resource() from the microblaze
      architecture code but failed to remove the comment that was added to
      it.
      
      Remove it since it has now become stale and it is quite confusing.

      Linus Torvalds authored
      Pull tracing updates from Steven Rostedt:
      
       - Restructure of lockdep and latency tracers
      
         This is the biggest change. Joel Fernandes restructured the hooks
         from irqs and preemption disabling and enabling. He got rid of a lot
         of the preprocessor #ifdef mess that they caused.
      
         He turned both lockdep and the latency tracers to use trace events
         inserted in the preempt/irqs disabling paths. But unfortunately,
         these started to cause issues in corner cases. Thus, parts of the
         code was reverted back to where lockdep and the latency tracers just
         get called directly (without using the trace events). But because the
         original change cleaned up the code very nicely we kept that, as well
         as the trace events for preempt and irqs disabling, but they are
         limited to not being called in NMIs.
      
       - Have trace events use SRCU for "rcu idle" calls. This was required
         for the preempt/irqs off trace events. But it also had to not allow
         them to be called in NMI context. Waiting till Paul makes an NMI safe
         SRCU API.
      
       - New notrace SRCU API to allow trace events to use SRCU.
      
       - Addition of mcount-nop option support
      
       - SPDX headers replacing GPL templates.
      
       - Various other fixes and clean ups.
      
       - Some fixes are marked for stable, but were not fully tested before
         the merge window opened.

      Raise the minimum required gcc version to 4.6 · cafa0010
      Joe Perches authored
      Various architectures fail to build properly with older versions of the
      gcc compiler.
      
      An example from Guenter Roeck in thread [1]:
      >
      >   In file included from ./include/linux/mm.h:17:0,
      >                    from ./include/linux/pid_namespace.h:7,

      > with gcc 4.4 (for unicore32) as well.
      
      So update the minimum required version of gcc to 4.6.

      ia64: Fix kernel BUG at lib/ioremap.c:72! · cc26ebbe
      Tony Luck authored
      Commit 0bbf47ea ("ia64: use asm-generic/io.h") results in a BUG
      while booting ia64.  This is because asm-generic/io.h defines
      PCI_IOBASE, which results in the function acpi_pci_root_remap_iospace()
      doing a lot of unnecessary (and wrong) things.
      
      I'd suggested an #if !CONFIG_IA64 in the functon, but Arnd suggested
      keeping the fix inside the arch/ia64 tree.

      net: sched: always disable bh when taking tcf_lock · 653cd284
      Vlad Buslov authored
      Recently, ops->init() and ops->dump() of all actions were modified to
      always obtain tcf_lock when accessing private action state. Actions that
      don't depend on tcf_lock for synchronization with their data path use
      non-bh locking API. However, tcf_lock is also used to protect rate
      estimator stats in softirq context by timer callback.
      
      Change ops->init() and ops->dump() of all actions to disable bh when using
      tcf_lock to prevent deadlock reported by following lockdep warning:

      Pull RISC-V updates from Palmer Dabbelt:
       "This contains some major improvements to the RISC-V port, including
        the necessary interrupt controller and timer support to actually make
        it to userspace. Support for three devices has been added:
      
         - the ISA-mandated timers on RISC-V systems.
      
         - the ISA-mandated first-level interrupt controller on RISC-V
           systems, which is handled as part of our core arch code because
           it's very small and tightly tied to the ISA.
      
         - SiFive's platform-level interrupt controller, which talks to the
           actual devices.
      
        In addition to these new devices, there are a handful of cleanups all
        over the RISC-V tree:
      
         - build fixes for various configurations:
            * A fix to the vDSO build's makefile so it respects CFLAGS.
            * The addition of __lshrti3, a libgcc derived function necessary
              for some 32-bit configurations.
            * !SMP && PERF_EVENTS
      
         - Cleanups to the arch code to remove the remnants of old versions of
           the drivers that were just properly submitted.
            * Some dead code from the timer driver, most of which wasn't ever
              even compiled.
            * Cleanups of some interrupt #defines, which are now local to the
              interrupt handling code.
      
         - Fixes to ptrace(), which while not being sufficient to fully make
           GDB work are at least sufficient to get simple GDB tasks to work.
      
         - Early printk support via RISC-V's architecturally mandated SBI
           console device.
      
         - A fix to our early debug trap handler to ensure it's always
           aligned.
      
        These patches have all been through a fairly extensive review process,
        but as this enables a whole pile of functionality (ie, userspace) I'm
        confident we'll need to submit a few more patches. The only concrete
        issues I know about are the sys_riscv_flush_icache patches, but as I
        managed to screw those up on Friday I figured it'd be best to let them
        bake another week.
      
        This tag boots a Fedora root filesystem on QEMU's master branch for
        me, and before this morning's rebase (from 4.18-rc8 to 4.18) it booted
        on the HiFive Unleashed.
      
        Thanks to Christoph Hellwig and the other guys at WD for getting the
        new drivers in shape!"
