      minmax: simplify and clarify min_t()/max_t() implementation · 017fa3e8
      Linus Torvalds authored
      This simplifies the min_t() and max_t() macros by no longer making them
      work in the context of a C constant expression.
      
      That means that you can no longer use them for static initializers or
      for array sizes in type definitions, but there were only a couple of
      such uses, and all of them were converted (famous last words) to use
      MIN_T/MAX_T instead.

      minmax: add a few more MIN_T/MAX_T users · 4477b39c
      Linus Torvalds authored
      Commit 3a7e02c0 ("minmax: avoid overly complicated constant
      expressions in VM code") added the simpler MIN_T/MAX_T macros in order
      to avoid some excessive expansion from the rather complicated regular
      min/max macros.
      
      The complexity of those macros stems from two issues:
      
       (a) trying to use them in situations that require a C constant
           expression (in static initializers and for array sizes)
      
       (b) the type sanity checking
      
      and MIN_T/MAX_T avoids both of these issues.
      
      Now, in the whole (long) discussion about all this, it was pointed out
      that the whole type sanity checking is entirely unnecessary for
      min_t/max_t which get a fixed type that the comparison is done in.
      
      But that still leaves min_t/max_t unnecessarily complicated due to
      worries about the C constant expression case.
      
      However, it turns out that there really aren't very many cases that use
      min_t/max_t for this, and we can just force-convert those.
      
      This does exactly that.
      
      Which in turn will then allow for much simpler implementations of
      min_t()/max_t().  All the usual "macros in all upper case will evaluate
      the arguments multiple times" rules apply.
      
      We should do all the same things for the regular min/max() vs MIN/MAX()
      cases, but that has the added complexity of various drivers defining
      their own local versions of MIN/MAX, so that needs another level of
      fixes first.

      kbuild: Fix '-S -c' in x86 stack protector scripts · 3415b10a
      Nathan Chancellor authored
      After a recent change in clang to stop consuming all instances of '-S'
      and '-c' [1], the stack protector scripts break due to the kernel's use
      of -Werror=unused-command-line-argument to catch cases where flags are
      not being properly consumed by the compiler driver:
      
        $ echo | clang -o - -x c - -S -c -Werror=unused-command-line-argument
        clang: error: argument unused during compilation: '-c' [-Werror,-Wunused-command-line-argument]
      
      This results in CONFIG_STACKPROTECTOR getting disabled because
      CONFIG_CC_HAS_SANE_STACKPROTECTOR is no longer set.
      
      '-c' and '-S' both instruct the compiler to stop at different stages of
      the pipeline ('-S' after compiling, '-c' after assembling), so having
      them present together in the same command makes little sense. In this
      case, the test wants to stop before assembling because it is looking at
      the textual assembly output of the compiler for either '%fs' or '%gs',
      so remove '-c' from the list of arguments to resolve the error.
      
      All versions of GCC continue to work after this change, along with
      versions of clang that do or do not contain the change mentioned above.

      Since ubiblock_exit() is now called from an init function,
      the __exit section no longer makes sense.
