      This `clang-analyzer` check flags the use of memset(), suggesting a more
      secure version of the API, such as memset_s(), which does not exist in
      the kernel:
      
        warning: Call to function 'memset' is insecure as it does not provide
        security checks introduced in the C11 standard. Replace with analogous

      kbuild: fix the modules order between drivers and libs · 11314751
      Masahiro Yamada authored
      Commit b2c88554 ("kbuild: update modules.order only when contained
      modules are updated") accidentally changed the modules order.
      
      Prior to that commit, the modules order was determined based on
      vmlinux-dirs, which lists core-y/m, drivers-y/m, libs-y/m, in this order.
      
      Now, subdir-modorder lists them in a different order: core-y/m, libs-y/m,
      drivers-y/m.
      
      Presumably, there was no practical issue because the modules in drivers
      and libs are orthogonal, but there is no reason to have this distortion.
      
      Get back to the original order.

      There are no instances of this warning in the tree across several
      difference architectures and configurations. This was added by
      commit 26ea6bb1 ("kbuild, LLVMLinux: Supress warnings unless W=1-3")
      back in 2014, where it might have been necessary, but there are no
      instances of it now so stop disabling it to increase warning coverage
      for clang.

      kbuild: dummy-tools: pretend we understand __LONG_DOUBLE_128__ · 0df499ea
      Jiri Slaby authored
      There is a test in powerpc's Kconfig which checks __LONG_DOUBLE_128__
      and sets CONFIG_PPC_LONG_DOUBLE_128 if it is understood by the compiler.
      
      We currently don't handle it, so this results in PPC_LONG_DOUBLE_128 not
      being in super-config generated by dummy-tools. So take this into
      account in the gcc script and preprocess __LONG_DOUBLE_128__ as "1".

      modpost: fix module versioning when a symbol lacks valid CRC · 5b8a9a8f
      Masahiro Yamada authored
      Since commit 7b453719 ("kbuild: link symbol CRCs at final link,
      removing CONFIG_MODULE_REL_CRCS"), module versioning is broken on
      some architectures. Loading a module fails with "disagrees about
      version of symbol module_layout".
      
      On such architectures (e.g. ARCH=sparc build with sparc64_defconfig),
      modpost shows a warning, like follows:
      
        WARNING: modpost: EXPORT symbol "_mcount" [vmlinux] version generation failed, symbol will not be versioned.
        Is "_mcount" prototyped in <asm/asm-prototypes.h>?
      
      Previously, it was a harmless warning (CRC check was just skipped),
      but now wrong CRCs are used for comparison because invalid CRCs are
      just skipped.
      
        $ sparc64-linux-gnu-nm -n vmlinux
          [snip]
        0000000000c2cea0 r __ksymtab__kstrtol

        0000000000c2cf18 r __ksymtab__raw_read_lock
        0000000000c2cf30 r __ksymtab__raw_read_lock_bh

        0000000000c53b48 D __crc__raw_read_lock_bh
      
      Please notice __crc__mcount is missing here.
      
      When the module subsystem looks up a CRC that comes after, it results
      in reading out a wrong address. For example, when __crc__printk is
      needed, the module subsystem reads 0xc53b44 instead of 0xc53b40.
      
      All CRC entries must be output for correct index accessing. Invalid
      CRCs will be unused, but are needed to keep the one-to-one mapping
      between __ksymtab_* and __crc_*.
      
      The best is to fix all modpost warnings, but several warnings are still
      remaining on less popular architectures.
