       "This contains the new HTE (hardware timestamping engine) subsystem
        that has been in the works for a couple of months now.
      
        The infrastructure provided allows for drivers to register as hardware
        timestamp providers, while consumers will be able to request events
        that they are interested in (such as GPIOs and IRQs) to be timestamped
        by the hardware providers.
      
        Note that this currently supports only one provider, but there seems
        to be enough interest in this functionality and we expect to see more
        drivers added once this is merged"

      modpost: simplify mod->name allocation · 8c9ce89c
      Masahiro Yamada authored
      mod->name is set to the ELF filename with the suffix ".o" stripped.
      
      The current code calls strdup() and free() to manipulate the string,
      but a simpler approach is to pass new_module() with the name length
      subtracted by 2.
      
      Also, check if the passed filename ends with ".o" before stripping it.
      
      The current code blindly chops the suffix:
      
          tmp[strlen(tmp) - 2] = '\0'
      
      It will cause buffer under-run if strlen(tmp) < 2;

      kbuild: factor out the common objtool arguments · b42d2306
      Masahiro Yamada authored
      scripts/Makefile.build and scripts/link-vmlinux.sh have similar setups
      for the objtool arguments.
      
      It was difficult to factor out them because all the vmlinux build rules
      were written in a shell script. It is somewhat tedious to touch the two
      files every time a new objtool option is supported.
      
      To reduce the code duplication, move the objtool for vmlinux.o into
      scripts/Makefile.vmlinux_o. Then, move the common macros to Makefile.lib
      so they are shared between Makefile.build and Makefile.vmlinux_o.

      Change the "make clean" rule to remove all the .tmp_* files.
      
      .tmp_objdiff is the only exception, which should be removed by

      Pull ptrace_stop cleanups from Eric Biederman:
       "While looking at the ptrace problems with PREEMPT_RT and the problems
        Peter Zijlstra was encountering with ptrace in his freezer rewrite I
        identified some cleanups to ptrace_stop that make sense on their own
        and move make resolving the other problems much simpler.
      
        The biggest issue is the habit of the ptrace code to change
        task->__state from the tracer to suppress TASK_WAKEKILL from waking up
        the tracee. No other code in the kernel does that and it is straight
        forward to update signal_wake_up and friends to make that unnecessary.
      
        Peter's task freezer sets frozen tasks to a new state TASK_FROZEN and
        then it stores them by calling "wake_up_state(t, TASK_FROZEN)" relying
        on the fact that all stopped states except the special stop states can
        tolerate spurious wake up and recover their state.
      
        The state of stopped and traced tasked is changed to be stored in
        task->jobctl as well as in task->__state. This makes it possible for
        the freezer to recover tasks in these special states, as well as
        serving as a general cleanup. With a little more work in that
        direction I believe TASK_STOPPED can learn to tolerate spurious wake
        ups and become an ordinary stop state.
      
        The TASK_TRACED state has to remain a special state as the registers
        for a process are only reliably available when the process is stopped
        in the scheduler. Fundamentally ptrace needs acess to the saved
        register values of a task.
      
        There are bunch of semi-random ptrace related cleanups that were found
        while looking at these issues.
      
        One cleanup that deserves to be called out is from commit 57b6de08
        ("ptrace: Admit ptrace_stop can generate spuriuos SIGTRAPs"). This
        makes a change that is technically user space visible, in the handling
        of what happens to a tracee when a tracer dies unexpectedly. According
        to our testing and our understanding of userspace nothing cares that
        spurious SIGTRAPs can be generated in that case"

        Commit 40966e31 ("kthread: Ensure struct kthread is present for

        kernel_execve to have struct kthread allocated for them. This struct
        kthread going away during execve in turned made a use after free of
        struct kthread possible.
      
        Here, commit 343f4c49 ("kthread: Don't allocate kthread_struct for
        init and umh") is enough to fix the use after free and is simple
        enough to be backportable.
      
        The rest of the changes pass struct kernel_clone_args to clean things
        up and cause the code to make sense.
      
        In making init and the user mode helpers tasks purely user mode tasks
        I ran into two complications. The function task_tick_numa was
        detecting tasks without an mm by testing for the presence of
        PF_KTHREAD. The initramfs code in populate_initrd_image was using
        flush_delayed_fput to ensuere the closing of all it's file descriptors
        was complete, and flush_delayed_fput does not work in a userspace
        thread.

        I have not found any, and neither has anyone else with the code

      firmware_loader: enable XZ by default if compressed support is enabled · 07953c54
      Linus Torvalds authored
      Commit 23cfbc6e ("firmware: Add the support for ZSTD-compressed
      firmware files") added support for ZSTD compression, but in the process
      also made the previously default XZ compression a config option.
      
      That means that anybody who upgrades their kernel and does a
      
          make oldconfig
      
      to update their configuration, will end up without the XZ compression
      that the configuration used to have.
      
      Add the 'default y' to make sure this doesn't happen.
      
      The whole compression question should probably be improved upon, since
      it is now possible to "enable" compression in the kernel config but not
      enable any actual compression algorithm, which makes it all very
      useless.  It makes no sense to ask Kconfig questions that enable
      situations that are nonsensical like that.
      
      This at least fixes the immediate problem of a kernel update resulting
      in a nonbootable machine because of a missed option.

         - The drivers/firmware/efi stub for booting from a standard UEFI
           firmware implementation. Both the original custom boot interface
           and a draft implementation of the EFI stub did not make it, so it
           is currently impossible to boot the kernel, until the loongarch
           specific portions get accepted into the UEFI subsystem
      
         - The drivers/irqchip/irq-loongson-*.c drivers are shared with the
           the MIPS port, but currently lack support for ACPI based booting,
           which will get merged through the irqchip subsystem.
      
         - Similarly, the drivers/pci/controller/pci-loongson.c needs to be
           modified for ACPI support, which will be merged through the PCI
           subsystem.
      
        While the port cannot actually be used before all the above are
        merged, having it in 5.19 helps to establish the user space ABI for
        the libc ports to build on, and to help any treewide changes in the
        mainline kernel get applied here as well.
      
        A gcc-12 based tool chains for build testing is now included in
      
          https://mirrors.edge.kernel.org/pub/tools/crosstool/"
      
      Original description from Huacai Chen:
       "LoongArch is a new RISC ISA, which is a bit like MIPS or RISC-V.
        LoongArch includes a reduced 32-bit version (LA32R), a standard 32-bit
        version (LA32S) and a 64-bit version (LA64). LoongArch use ACPI as its
        boot protocol LoongArch-specific interrupt controllers (similar to APIC)
        are already added in the next revision of ACPI Specification (current
        revision is 6.4).
      
        This patchset is adding basic LoongArch support in mainline kernel, we
        can see a complete snapshot here:

      Linus Torvalds authored
      Pull more s390 updates from Heiko Carstens:
       "Just a couple of small improvements, bug fixes and cleanups:
      
         - Add Eric Farman as maintainer for s390 virtio drivers.
      
         - Improve machine check handling, and avoid incorrectly injecting a
           machine check into a kvm guest.
      
         - Add cond_resched() call to gmap page table walker in order to avoid
           possible huge latencies. Also use non-quiesing sske instruction to
           speed up storage key handling.
      
         - Add __GFP_NORETRY to KEXEC_CONTROL_MEMORY_GFP so s390 behaves
           similar like common code.
      
         - Get sie control block address from correct stack slot in perf event
           code. This fixes potential random memory accesses.
      
         - Change uaccess code so that the exception handler sets the result
           of get_user() and __get_kernel_nofault() to zero in case of a
           fault. Until now this was done via input parameters for inline
           assemblies. Doing it via fault handling is what most or even all
           other architectures are doing.
