      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.

      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.
