      tree-wide: replace config_enabled() with IS_ENABLED() · 97f2645f
      由 Masahiro Yamada 提交于 
      The use of config_enabled() against config options is ambiguous.  In
practical terms, config_enabled() is equivalent to IS_BUILTIN(), but the
author might have used it for the meaning of IS_ENABLED().  Using
IS_ENABLED(), IS_BUILTIN(), IS_MODULE() etc.  makes the intention
clearer.

This commit replaces config_enabled() with IS_ENABLED() where possible.
This commit is only touching bool config options.

I noticed two cases where config_enabled() is used against a tristate
option:

 - config_enabled(CONFIG_HWMON)
  [ drivers/net/wireless/ath/ath10k/thermal.c ]

 - config_enabled(CONFIG_BACKLIGHT_CLASS_DEVICE)
  [ drivers/gpu/drm/gma500/opregion.c ]

I did not touch them because they should be converted to IS_BUILTIN()
in order to keep the logic, but I was not sure it was the authors'
intention.

      fs/proc: Add compiler check for -Wno-override-init to support gcc < 4.2 · 4b2e0162
      由 Geert Uytterhoeven 提交于 
      With gcc < 4.2 (e.g. 4.1.2):

      CC      fs/proc/task_mmu.o
    cc1: error: unrecognized command line option "-Wno-override-init"

To fix this, only enable the compiler option when it is actually
supported by the compiler.
