      Documentation/llvm: Note s390 LLVM=1 support with LLVM 18.1.0 and newer · 978fa00e
      Nathan Chancellor authored
      As of the first s390 pull request during the 6.9 merge window,
      commit 691632f0 ("Merge tag 's390-6.9-1' of
      git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux"
      
      ), s390 can be
      built with LLVM=1 when using LLVM 18.1.0, which is the first version
      that has SystemZ support implemented in ld.lld and llvm-objcopy.
      
      Update the supported architectures table in the Kbuild LLVM
      documentation to note this explicitly to make it more discoverable by
      users and other developers. Additionally, this brings s390 in line with
      the rest of the architectures in the table, which all support LLVM=1.

      kbuild: Disable KCSAN for autogenerated *.mod.c intermediaries · 54babdc0
      Borislav Petkov (AMD) authored
      
      
      When KCSAN and CONSTRUCTORS are enabled, one can trigger the
      
        "Unpatched return thunk in use. This should not happen!"
      
      catch-all warning.
      
      Usually, when objtool runs on the .o objects, it does generate a section
      .return_sites which contains all offsets in the objects to the return
      thunks of the functions present there. Those return thunks then get
      patched at runtime by the alternatives.
      
      KCSAN and CONSTRUCTORS add this to the object file's .text.startup
      section:

        Disassembly of section .text.startup:

      which, if it is built as a module goes through the intermediary stage of
      creating a <module>.mod.c file which, when translated, receives a second

      Objtool has run already so that second constructor's return thunk cannot
      be added to the .return_sites section and thus the return thunk remains
      unpatched and the warning rightfully fires.
      
      Drop KCSAN flags from the mod.c generation stage as those constructors
      do not contain data races one would be interested about.

      kbuild: make -Woverride-init warnings more consistent · c40845e3
      Arnd Bergmann authored
      The -Woverride-init warn about code that may be intentional or not,
      but the inintentional ones tend to be real bugs, so there is a bit of
      disagreement on whether this warning option should be enabled by default
      and we have multiple settings in scripts/Makefile.extrawarn as well as
      individual subsystems.
      
      Older versions of clang only supported -Wno-initializer-overrides with
      the same meaning as gcc's -Woverride-init, though all supported versions
      now work with both. Because of this difference, an earlier cleanup of
      mine accidentally turned the clang warning off for W=1 builds and only
      left it on for W=2, while it's still enabled for gcc with W=1.
      
      There is also one driver that only turns the warning off for newer
      versions of gcc but not other compilers, and some but not all the
      Makefiles still use a cc-disable-warning conditional that is no
      longer needed with supported compilers here.
      
      Address all of the above by removing the special cases for clang
      and always turning the warning off unconditionally where it got
      in the way, using the syntax that is supported by both compilers.

       "Fully half this pull is updates to lpfc and qla2xxx which got
        committed just as the merge window opened. A sizeable fraction of the

        the case of lpfc), so rather than splitting the few actual
        enhancements out, we're just adding the drivers to the -rc1 pull.
      
        The enhancements for lpfc are log message removals, copyright updates
        and three patches redefining types. For qla2xxx it's just removing a
        debug message on module removal and the manufacturer detail update.
      
        The two major fixes are the sg teardown race and a core error leg
        problem with the procfs directory not being removed if we destroy a
        created host that never got to the running state. The rest are minor

      x86/build: Use obj-y to descend into arch/x86/virt/ · 3f1a9bc5
      Masahiro Yamada authored
      Commit c33621b4
      
       ("x86/virt/tdx: Wire up basic SEAMCALL functions")
      introduced a new instance of core-y instead of the standardized obj-y
      syntax.
      
      X86 Makefiles descend into subdirectories of arch/x86/virt inconsistently;
      into arch/x86/virt/ via core-y defined in arch/x86/Makefile, but into
      arch/x86/virt/svm/ via obj-y defined in arch/x86/Kbuild.
      
      This is problematic when you build a single object in parallel because
      multiple threads attempt to build the same file.
      
        $ make -j$(nproc) arch/x86/virt/vmx/tdx/seamcall.o
          [ snip ]
          AS      arch/x86/virt/vmx/tdx/seamcall.o

      Use the obj-y syntax, as it works correctly.
