      kconfig: add build-only configurator targets · 4bf6a9af
      Randy Dunlap authored
      Add build-only targets for build_menuconfig, build_nconfig,
      build_xconfig, and build_gconfig.
      (targets must end in "config" to qualify in top-level Makefile)
      
      This allows these target to be built without execution (e.g., to
      look for errors or warnings) and/or to be built and checked by sparse.

      scripts/dtc: consolidate include path options in Makefile · e3fd9b53
      Masahiro Yamada authored
      It is tedious to specify extra compiler options for every file.
      HOST_EXTRACFLAGS is useful to add options to all files in a
      directory.
      
      -I$(src)/libfdt is needed for all the files in this directory
      to include libfdt_env.h etc. from scripts/dtc/libfdt/.
      
      On the other hand, -I$(src) is used to include check-in headers
      from generated C files.  Thus, I added it only to dtc-lexer.lex.o
      and dtc-parser.tab.o .

        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"

      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.
