      Pull locking updates from Thomas Gleixner:
       "A set of locking fixes and updates:
      
         - Untangle the header spaghetti which causes build failures in
           various situations caused by the lockdep additions to seqcount to
           validate that the write side critical sections are non-preemptible.
      
         - The seqcount associated lock debug addons which were blocked by the
           above fallout.
      
           seqcount writers contrary to seqlock writers must be externally
           serialized, which usually happens via locking - except for strict
           per CPU seqcounts. As the lock is not part of the seqcount, lockdep
           cannot validate that the lock is held.
      
           This new debug mechanism adds the concept of associated locks.
           sequence count has now lock type variants and corresponding
           initializers which take a pointer to the associated lock used for
           writer serialization. If lockdep is enabled the pointer is stored
           and write_seqcount_begin() has a lockdep assertion to validate that
           the lock is held.
      
           Aside of the type and the initializer no other code changes are
           required at the seqcount usage sites. The rest of the seqcount API
           is unchanged and determines the type at compile time with the help
           of _Generic which is possible now that the minimal GCC version has
           been moved up.
      
           Adding this lockdep coverage unearthed a handful of seqcount bugs
           which have been addressed already independent of this.
      
           While generally useful this comes with a Trojan Horse twist: On RT
           kernels the write side critical section can become preemtible if
           the writers are serialized by an associated lock, which leads to
           the well known reader preempts writer livelock. RT prevents this by
           storing the associated lock pointer independent of lockdep in the
           seqcount and changing the reader side to block on the lock when a
           reader detects that a writer is in the write side critical section.
      
         - Conversion of seqcount usage sites to associated types and
           initializers"

      Linus Torvalds authored
      Pull f2fs updates from Jaegeuk Kim:
       "In this round, we've added two small interfaces: (a) GC_URGENT_LOW
        mode for performance and (b) F2FS_IOC_SEC_TRIM_FILE ioctl for
        security.
      
        The new GC mode allows Android to run some lower priority GCs in
        background, while new ioctl discards user information without race
        condition when the account is removed.
      
        In addition, some patches were merged to address latency-related
        issues. We've fixed some compression-related bug fixes as well as edge
        race conditions.
      
        Enhancements:
         - add GC_URGENT_LOW mode in gc_urgent
         - introduce F2FS_IOC_SEC_TRIM_FILE ioctl
         - bypass racy readahead to improve read latencies
         - shrink node_write lock coverage to avoid long latency
      
        Bug fixes:
         - fix missing compression flag control, i_size, and mount option
         - fix deadlock between quota writes and checkpoint
         - remove inode eviction path in synchronous path to avoid deadlock
         - fix to wait GCed compressed page writeback
         - fix a kernel panic in f2fs_is_compressed_page
         - check page dirty status before writeback
         - wait page writeback before update in node page write flow
         - fix a race condition between f2fs_write_end_io and f2fs_del_fsync_node_entry
      
        We've added some minor sanity checks and refactored trivial code
        blocks for better readability and debugging information"

       "This is the bulk of the pin control changes for the v5.9 kernel
        series:
      
        Core changes:
      
         - The GPIO patch "gpiolib: Introduce for_each_requested_gpio_in_range()
           macro" was put in an immutable branch and merged into the pinctrl
           tree as well. We see these changes also here.
      
         - Improved debug output for pins used as GPIO.
      
        New drivers:
      
         - Ocelot Sparx5 SoC driver.
      
         - Intel Emmitsburg SoC subdriver.
      
         - Intel Tiger Lake-H SoC subdriver.
      
         - Qualcomm PM660 SoC subdriver.
      
         - Renesas SH-PFC R8A774E1 subdriver.
      
        Driver improvements:
      
         - Linear improvement and cleanups of the Intel drivers for
           Cherryview, Lynxpoint, Baytrail etc. Improved locking among other
           things.
      
         - Renesas SH-PFC has added support for RPC pins, groups, and
           functions to r8a77970 and r8a77980.
      
         - The newere Freescale (now NXP) i.MX8 pin controllers have been
           modularized. This is driven by the Google Android GKI initiative I
           think.
      
         - Open drain support for pins on the Qualcomm IPQ4019.
      
         - The Ingenic driver can handle both edges IRQ detection.
      
         - A big slew of documentation fixes all over the place.
      
         - A few irqchip template conversions by yours truly.

      kbuild: introduce hostprogs-always-y and userprogs-always-y · faabed29
      Masahiro Yamada authored
      To build host programs, you need to add the program names to 'hostprogs'
      to use the necessary build rule, but it is not enough to build them
      because there is no dependency.
      
      There are two types of host programs: built as the prerequisite of
      another (e.g. gen_crc32table in lib/Makefile), or always built when
      Kbuild visits the Makefile (e.g. genksyms in scripts/genksyms/Makefile).
      
      The latter is typical in Makefiles under scripts/, which contains host
      programs globally used during the kernel build. To build them, you need
      to add them to both 'hostprogs' and 'always-y'.
      
      This commit adds hostprogs-always-y as a shorthand.
      
      The same applies to user programs. net/bpfilter/Makefile builds
      bpfilter_umh on demand, hence always-y is unneeded. In contrast,
      programs under samples/ are added to both 'userprogs' and 'always-y'
      so they are always built when Kbuild visits the Makefiles.
      
      userprogs-always-y works as a shorthand.

      kbuild: sort hostprogs before passing it to ifneq · 85569d19
      Masahiro Yamada authored
      The conditional:
      
        ifneq ($(hostprogs),)
      
      ... is evaluated to true if $(hostprogs) does not contain any word but
      whitespace characters.
      
        ifneq ($(strip $(hostprogs)),)
      
      ... is a safe way to avoid interpreting whitespace as a non-empty value,
      but I'd rather want to use the side-effect of $(sort ...) to do the
      equivalent.
      
      $(sort ...) is used in scripts/Makefile.host in order to drop duplication
      in $(hostprogs). It is also useful to strip excessive spaces.
      
      Move $(sort ...) before evaluating the ifneq.

      kbuild: move host .so build rules to scripts/gcc-plugins/Makefile · 42640b13
      Masahiro Yamada authored
      The host shared library rules are currently implemented in
      scripts/Makefile.host, but actually GCC-plugin is the only user of
      them. (The VDSO .so files are built for the target by different
      build rules) Hence, they do not need to be treewide available.
      
      Move all the relevant build rules to scripts/gcc-plugins/Makefile.
      
      I also optimized the build steps so *.so is directly built from .c
      because every upstream plugin is compiled from a single source file.
      
      I am still keeping the multi-file plugin support, which Kees Cook
      mentioned might be needed by out-of-tree plugins.
      (https://lkml.org/lkml/2019/1/11/1107)
      
      If the plugin, foo.so, is compiled from two files foo.c and foo2.c,
      then you can do like follows:
      
        foo-objs := foo.o foo2.o
      
      Single-file plugins do not need the *-objs notation.

      	  If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
                  If both the HTTP and HTTPS versions
                  return 200 OK and serve the same content:

      kbuild: trace functions in subdirectories of lib/ · b16838c6
      Masahiro Yamada authored
      ccflags-remove-$(CONFIG_FUNCTION_TRACER) += $(CC_FLAGS_FTRACE)
      
      exists here in sub-directories of lib/ to keep the behavior of
      commit 2464a609 ("ftrace: do not trace library functions").
      
      Since that commit, not only the objects in lib/ but also the ones in
      the sub-directories are excluded from ftrace (although the commit
      description did not explicitly mention this).
      
      However, most of library functions in sub-directories are not so hot.
      Re-add them to ftrace.
      
      Going forward, only the objects right under lib/ will be excluded.

      kbuild: introduce ccflags-remove-y and asflags-remove-y · 15d5761a
      Masahiro Yamada authored
      CFLAGS_REMOVE_<file>.o filters out flags when compiling a particular
      object, but there is no convenient way to do that for every object in
      a directory.
      
      Add ccflags-remove-y and asflags-remove-y to make it easily.
      
      Use ccflags-remove-y to clean up some Makefiles.
      
      The add/remove order works as follows:
      
       [1] KBUILD_CFLAGS specifies compiler flags used globally
      
       [2] ccflags-y adds compiler flags for all objects in the
           current Makefile
      
       [3] ccflags-remove-y removes compiler flags for all objects in the
           current Makefile (New feature)
      
       [4] CFLAGS_<file> adds compiler flags per file.
      
       [5] CFLAGS_REMOVE_<file> removes compiler flags per file.
      
      Having [3] before [4] allows us to remove flags from most (but not all)
      objects in the current Makefile.
      
      For example, kernel/trace/Makefile removes $(CC_FLAGS_FTRACE)
      from all objects in the directory, then adds it back to
      trace_selftest_dynamic.o and CFLAGS_trace_kprobe_selftest.o
      
      The same applies to lib/livepatch/Makefile.
      
      Please note ccflags-remove-y has no effect to the sub-directories.
      In contrast, the previous notation got rid of compiler flags also from
      all the sub-directories.
      
      The following are not affected because they have no sub-directories:
      
        arch/arm/boot/compressed/
        arch/powerpc/xmon/
        arch/sh/
        kernel/trace/
      
      However, lib/ has several sub-directories.
      
      To keep the behavior, I added ccflags-remove-y to all Makefiles
      in subdirectories of lib/, except the following:
      
        lib/vdso/Makefile        - Kbuild does not descend into this Makefile
        lib/raid/test/Makefile   - This is not used for the kernel build
      
      I think commit 2464a609 ("ftrace: do not trace library functions")
      excluded too much. In the next commit, I will remove ccflags-remove-y
      from the sub-directories of lib/.

      kbuild: do not export LDFLAGS_vmlinux · 3ec8a5b3
      Masahiro Yamada authored
      When you clean the build tree for ARCH=arm, you may see the following
      error message from 'nm' command:
      
      $ make -j24 ARCH=arm clean
        CLEAN   arch/arm/crypto
        CLEAN   arch/arm/kernel

        CLEAN   lib
        CLEAN   usr
        CLEAN   net/wireless
        CLEAN   drivers/firmware/efi/libstub
      nm: 'arch/arm/boot/compressed/../../../../vmlinux': No such file
      /bin/sh: 1: arithmetic expression: expecting primary: " "
        CLEAN   arch/arm/boot/compressed
        CLEAN   drivers/scsi
        CLEAN   drivers/tty/vt
        CLEAN   arch/arm/boot
        CLEAN   vmlinux.symvers modules.builtin modules.builtin.modinfo
      
      Even if you rerun the same command, the error message will not be
      shown despite vmlinux is already gone.
      
      To reproduce it, the parallel option -j is needed. Single thread
      cleaning always executes 'archclean', 'vmlinuxclean' in this order,
      so vmlinux still exists when arch/arm/boot/compressed/ is cleaned.
      
      Looking at arch/arm/boot/compressed/Makefile does not help understand
      the reason of the error message. Both KBSS_SZ and LDFLAGS_vmlinux are
      assigned with '=' operator, hence, they are not expanded unless used.
      Obviously, 'make clean' does not use them.
      
      In fact, the root cause exists in the top Makefile:
      
        export LDFLAGS_vmlinux
      
      Since LDFLAGS_vmlinux is an exported variable, LDFLAGS_vmlinux in
      arch/arm/boot/compressed/Makefile is expanded when scripts/Makefile.clean
      has a command to execute. This is why the error message shows up only
      when there exist build artifacts in arch/arm/boot/compressed/.
      
      Adding 'unexport LDFLAGS_vmlinux' to arch/arm/boot/compressed/Makefile
      will fix it as far as ARCH=arm is concerned, but I think the proper fix
      is to get rid of 'export LDFLAGS_vmlinux' from the top Makefile.
      
      LDFLAGS_vmlinux in the top Makefile contains linker flags for the top
      vmlinux. LDFLAGS_vmlinux in arch/arm/boot/compressed/Makefile is for
      arch/arm/boot/compressed/vmlinux. They just happen to have the same
      variable name, but are used for different purposes. Stop shadowing
      LDFLAGS_vmlinux.
      
      This commit passes LDFLAGS_vmlinux to scripts/link-vmlinux.sh via a
      command line parameter instead of via an environment variable. LD and
      KBUILD_LDFLAGS are exported, but I did the same for consistency. Anyway,
      they must be included in cmd_link-vmlinux to allow if_changed to detect
      the changes in LD or KBUILD_LDFLAGS.
      
      The following Makefiles are not affected:
      
        arch/arm/boot/compressed/Makefile
        arch/h8300/boot/compressed/Makefile
        arch/nios2/boot/compressed/Makefile
        arch/parisc/boot/compressed/Makefile
        arch/s390/boot/compressed/Makefile
        arch/sh/boot/compressed/Makefile
        arch/sh/boot/romimage/Makefile
        arch/x86/boot/compressed/Makefile
      
      They use ':=' or '=' to clear the LDFLAGS_vmlinux inherited from the
      top Makefile.
      
      We need to take a closer look at the impact to unicore32 and xtensa.
      
      arch/unicore32/boot/compressed/Makefile only uses '+=' operator for
      LDFLAGS_vmlinux. So, the decompressor previously inherited the linker
      flags from the top Makefile.
      
      However, commit 70fac51f ("unicore32 additional architecture files:
      boot process") was merged before commit 1f2bfbd0 ("kbuild: link of
      vmlinux moved to a script"). So, I rather consider this is a bug fix of
      1f2bfbd0.
      
      arch/xtensa/boot/boot-elf/Makefile is also affected, but this is also
      considered a fix for the same reason. It did not inherit LDFLAGS_vmlinux
      when commit 4bedea94 ("[PATCH] xtensa: Architecture support for
      Tensilica Xtensa Part 2") was merged. I deleted $(LDFLAGS_vmlinux),
      which is now empty.

      kbuild: always create directories of targets · cc8a51ca
      Masahiro Yamada authored
      Currently, the directories of objects are automatically created
      only for O= builds.
      
      It should not hurt to cater to this for in-tree builds too.

      arm64: Fix __cpu_logical_map undefined issue · eaecca9e
      Kefeng Wang authored
      The __cpu_logical_map undefined issue occued when the new
      tegra194-cpufreq drvier building as a module.
      
      ERROR: modpost: "__cpu_logical_map" [drivers/cpufreq/tegra194-cpufreq.ko] undefined!
      
      The driver using cpu_logical_map() macro which will expand to
      __cpu_logical_map, we can't access it in a drvier. Let's turn
      cpu_logical_map() into a C wrapper and export it to fix the
      build issue.
      
      Also create a function set_cpu_logical_map(cpu, hwid) when assign
      a value to cpu_logical_map(cpu).

      These 'compile-time allocated' memory buffers can occupy more than one
      page and each enum increment is page-sized. So improve the note about it.

      Pull tracing updates from Steven Rostedt:
      
       - The biggest news in that the tracing ring buffer can now time events
         that interrupted other ring buffer events.
      
         Before this change, if an interrupt came in while recording another
         event, and that interrupt also had an event, those events would all
         have the same time stamp as the event it interrupted.
      
         Now, with the new design, those events will have a unique time stamp
         and rightfully display the time for those events that were recorded
         while interrupting another event.
      
       - Bootconfig how has an "override" operator that lets the users have a
         default config, but then add options to override the default.
      
       - A fix was made to properly filter function graph tracing to the
         ftrace PIDs. This came in at the end of the -rc cycle, and needs to
         be backported.
