      initramfs: move gen_initramfs_list.sh from scripts/ to usr/ · f6f57a46
      Masahiro Yamada authored
      scripts/gen_initramfs_list.sh is only invoked from usr/Makefile.
      Move it so that all tools to create initramfs are self-contained
      in the usr/ directory.

      Coccinelle: remove pci_alloc_consistent semantic to detect in zalloc-simple.cocci · 6fbd8569
      zhong jiang authored
      Because pci_alloc_consistent has been deprecated. We prefer to use
      dma_alloc_coherent directly. Therefore, we should remove pci_alloc_consistent
      to increase the confidence.

      kbuild: make sorting initramfs contents independent of locale · f55f2328
      Andrzej Pietrasiewicz authored
      Some LANG values (e.g. pl_PL.UTF-8) cause the sort command to output
      files before their parent directories, which makes them inaccessible for
      the kernel. In other words, when the kernel populates the rootfs, it is
      unable to create files whose parent directories have not been yet created.
      
      This patch makes sorting use the default (LANG=C) locale, which results in
      correctly laid out initramfs images (parent directories before files).

      kconfig: suppress "configuration written to .config" for syncconfig · 9a9ddcf4
      Masahiro Yamada authored
      The top-level Makefile invokes "make syncconfig" when necessary.
      Then, Kconfig displays the following message when .config is updated.
      
        #
        # configuration written to .config
        #
      
      It is distracting because "make syncconfig" happens during the build
      stage, and does nothing important in most cases.

      kconfig: improve the recursive dependency report · f498926c
      Masahiro Yamada authored
      This commit improves the messages of the recursive dependency.
      Currently, sym->dir_dep.expr is not checked.  Hence, any dependency
      in property visibility is regarded as the dependency of the symbol.
      
      [Test Code 1]
      
        config A
                bool "a"
                depends on B
      
        config B
                bool "b"
                depends on A
      
      [Test Code 2]
      
        config A
                bool "a" if B
      
        config B
                bool "b"
                depends on A
      
      For both cases above, the same message is displayed:
      
              symbol B depends on A
              symbol A depends on B
      
      This commit changes the message for the latter, like this:
      
              symbol B depends on A
              symbol A prompt is visible depending on B
      
      Also, 'select' and 'imply' are distinguished.

      kconfig: report recursive dependency involving 'imply' · 5e8c5299
      Masahiro Yamada authored
      Currently, Kconfig does not complain about the recursive dependency
      where 'imply' keywords are involved.
      
      [Test Code]
      
        config A
                bool "a"
      
        config B
                bool "b"
                imply A
                depends on A
      
      In the code above, Kconfig cannot calculate the symbol values correctly
      due to the circular dependency.  For example, allyesconfig followed by
      syncconfig results in an odd behavior because CONFIG_B becomes visible
      in syncconfig.
      
        $ make allyesconfig
        scripts/kconfig/conf  --allyesconfig Kconfig
        #
        # configuration written to .config
        #
        $ cat .config
        #
        # Automatically generated file; DO NOT EDIT.
        # Main menu
        #
        CONFIG_A=y
        $ make syncconfig
        scripts/kconfig/conf  --syncconfig Kconfig
        *
        * Restart config...
        *
        *
        * Main menu
        *
        a (A) [Y/n/?] y
          b (B) [N/y/?] (NEW)
      
      To detect this correctly, sym_check_expr_deps() should recurse to
      not only sym->rev_dep.expr but also sym->implied.expr .
      
      At this moment, sym_check_print_recursive() cannot distinguish
      'select' and 'imply' since it does not know the precise context
      where the recursive dependency has been hit.  This will be solved
      by the next commit.
      
      In fact, even the document and the unit-test are confused.  Using
      'imply' does not solve recursive dependency since 'imply' addresses
      the unmet direct dependency, which 'select' could cause.

      kconfig: error out when seeing recursive dependency · f1575595
      Masahiro Yamada authored
      Originally, recursive dependency was a fatal error for Kconfig
      because Kconfig cannot compute symbol values in such a situation.
      
      Commit d595cea6 ("kconfig: print more info when we see a recursive
      dependency") changed it to a warning, which I guess was not intentional.
      
      Get it back to an error again.
      
      Also, rename the unit test directory "warn_recursive_dep" to
      "err_recursive_dep" so that it matches to the behavior.

      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 .

      Linus Torvalds authored
      Pull i2c updates from Wolfram Sang:
      
       - the core has now a lockless variant of i2c_smbus_xfer. Some open
         coded versions of this got removed in drivers. This also enables
         proper SCCB support in regmap.
      
       - locking got a more precise naming. i2c_{un}lock_adapter() had to go,
         and we know use i2c_lock_bus() consistently with flags like
         I2C_LOCK_ROOT_ADAPTER and I2C_LOCK_SEGMENT to avoid ambiguity.
      
       - the gpio fault injector got a new delicate testcase
      
       - the bus recovery procedure got fixed to handle the new testcase
         correctly
      
       - a new quirk flag for controllers not able to handle zero length
         messages together with driver updates to use it
      
       - new drivers: FSI bus attached I2C masters, GENI I2C controller, Owl
         family S900
      
       - and a good set of driver improvements and bugfixes

       "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"

      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,

      So update the minimum required version of gcc to 4.6.

       - Update Documentation/process/changes.rst
      
       - Remove and consolidate version test blocks in compiler-gcc.h for
         versions lower than 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.
