      usb: chipidea: make configs for glue drivers visible with EXPERT · d818320e
      Lukas Bulwahn authored
      Commit 6a108a14 ("kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT")
      introduces CONFIG_EXPERT to carry the previous intent of CONFIG_EMBEDDED
      and just gives that intent a much better name. That has been clearly a good
      and long overdue renaming, and it is clearly an improvement to the kernel
      build configuration that has shown to help managing the kernel build
      configuration in the last decade.
      
      However, rather than bravely and radically just deleting CONFIG_EMBEDDED,
      this commit gives CONFIG_EMBEDDED a new intended semantics, but keeps it
      open for future contributors to implement that intended semantics:
      
          A new CONFIG_EMBEDDED option is added that automatically selects
          CONFIG_EXPERT when enabled and can be used in the future to isolate
          options that should only be considered for embedded systems (RISC
          architectures, SLOB, etc).
      
      Since then, this CONFIG_EMBEDDED implicitly had two purposes:
      
        - It can make even more options visible beyond what CONFIG_EXPERT makes
          visible. In other words, it may introduce another level of enabling the
          visibility of configuration options: always visible, visible with
          CONFIG_EXPERT and visible with CONFIG_EMBEDDED.
      
        - Set certain default values of some configurations differently,
          following the assumption that configuring a kernel build for an
          embedded system generally starts with a different set of default values
          compared to kernel builds for all other kind of systems.
      
      Considering the first purpose, at the point in time where CONFIG_EMBEDDED
      was renamed to CONFIG_EXPERT, CONFIG_EXPERT already made 130 more options
      become visible throughout all different menus for the kernel configuration.
      Over the last decade, this has gradually increased, so that currently, with
      CONFIG_EXPERT, roughly 170 more options become visible throughout all
      different menus for the kernel configuration. In comparison, currently with
      CONFIG_EMBEDDED enabled, just seven more options are visible, one in x86,
      one in arm, and five for the ChipIdea Highspeed Dual Role Controller.
      
      As the numbers suggest, these two levels of enabling the visibility of even
      more configuration options---beyond what CONFIG_EXPERT enables---never
      evolved to a good solution in the last decade. In other words, this
      additional level of visibility of configuration option with CONFIG_EMBEDDED
      compared to CONFIG_EXPERT has since its introduction never become really
      valuable. It requires quite some investigation to actually understand what
      is additionally visible and it does not differ significantly in complexity
      compared to just enabling CONFIG_EXPERT. This CONFIG_EMBEDDED---or any
      other config to show more detailed options beyond CONFIG_EXPERT---is
      unlikely to be valuable unless somebody puts significant effort in
      identifying how such visibility options can be properly split and creating
      clear criteria, when some config option is visible with CONFIG_EXPERT and
      when some config option is visible only with some further option enabled
      beyond CONFIG_EXPERT, such as CONFIG_EMBEDDED attempted to do. For now, it
      is much more reasonable to simply make those additional seven options that
      visible with CONFIG_EMBEDDED, visible with CONFIG_EXPERT, and then remove
      CONFIG_EMBEDDED. If anyone spends significant effort in structuring the
      visibility of config options, they may re-introduce suitable new config
      options simply as they see fit.
      
      Make the configs for usb chipidea glue drivers visible when CONFIG_EXPERT
      is enabled.

      Pull powerpc fixes from Michael Ellerman:
      
       - Fix handling of PCI domains in /proc on 32-bit systems using the
         recently added support for numbering buses from zero for each domain.
      
       - A fix and a revert for some changes to use READ/WRITE_ONCE() which
         caused problems with KASAN enabled due to sanitisation calls being
         introduced in low-level paths that can't cope with it.
      
       - Fix build errors on 32-bit caused by the syscall table being
         misaligned sometimes.
      
       - Two fixes to get IBM Cell native machines booting again, which had
         bit-rotted while my QS22 was temporarily out of action.
      
       - Fix the papr_scm driver to not assume the order of events returned by
         the hypervisor is stable, and a related compile fix.

      Makefile.extrawarn: re-enable -Wformat for clang; take 2 · b0839b28
      Nick Desaulniers authored
      -Wformat was recently re-enabled for builds with clang, then quickly
      re-disabled, due to concerns stemming from the frequency of default
      argument promotion related warning instances.
      
      commit 258fafcd ("Makefile.extrawarn: re-enable -Wformat for clang")
      commit 21f9c8a1 ("Revert "Makefile.extrawarn: re-enable -Wformat for clang"")
      
      ISO WG14 has ratified N2562 to address default argument promotion
      explicitly for printf, as part of the upcoming ISO C2X standard.
      
      The behavior of clang was changed in clang-16 to not warn for the cited
      cases in all language modes.
      
      Add a version check, so that users of clang-16 now get the full effect
      of -Wformat. For older clang versions, re-enable flags under the
      -Wformat group that way users still get some useful checks related to
      format strings, without noisy default argument promotion warnings. I
      intentionally omitted -Wformat-y2k and -Wformat-security from being
      re-enabled, which are also part of -Wformat in clang-16.
