      Restore gcc check in mips asm/unroll.h · d4e60453
      Cesar Eduardo Barros authored
      While raising the gcc version requirement to 4.9, the compile-time check
      in the unroll macro was accidentally changed from being used on gcc and
      clang to being used on clang only.
      
      Restore the gcc check, changing it from "gcc >= 4.7" to "all gcc".
      
      [ We should probably remove this all entirely: if we remove the check
        for CLANG, then the check for GCC can go away. Older versions of clang
        are not really appropriate or supported for kernel builds - Linus ]

      kbuild: Move -Wtype-limits to W=2 · 355a3587
      Rikard Falkeborn authored
      -Wtype-limits is included in -Wextra which is added at W=1. It warns
      (among other things) that 'comparison of an unsigned variable `< 0` is
      always false. This causes noisy warnings, especially when used in
      macros, hence it is more suitable for W=2.
