ARM: npcm: Bring back GPIOLIB support

The CONFIG_ARCH_REQUIRE_GPIOLIB is gone since commit 65053e1a7743 ("gpio: delete ARCH_[WANTS_OPTIONAL|REQUIRE]_GPIOLIB") and all platforms should explicitly select GPIOLIB to have it.

2.17.1

CONFIG_MMC_BLOCK_BOUNCE is gone since commit c3dccb74be28 ("mmc: core:
Delete bounce buffer Kconfig option").

CONFIG_LBDAF is gone since commit 72deb455b5ec ("block: remove CONFIG_LBDAF").

CONFIG_IOSCHED_DEADLINE and CONFIG_IOSCHED_CFQ are gone since commit f382fb0bcef4 ("block: remove legacy IO schedulers").

The IOSCHED_DEADLINE was replaced by MQ_IOSCHED_DEADLINE and it will be now enabled by default (along with MQ_IOSCHED_KYBER).

The IOSCHED_BFQ seems to replace IOSCHED_CFQ so select it in configs previously choosing the latter.

CONFIG_CROSS_COMPILE is gone since commit f1089c92da79 ("kbuild: remove CONFIG_CROSS_COMPILE support").

Hi Krzysztof.

There seems there are a lot more of these unused CONFIG_<foo> symbols in various defconfigs. (just for arm and treewide below)

  sort | uniq > config_symbols

# find CONFIG_ symbols in arm defconfigs

$ git grep -w -oh -P 'CONFIG_\w+' 'arch/arm*/*defconfig*' | \
  sort | uniq > used_in_arm_defconfigs

# find all the unused symbols

$ cat used_in_arm_defconfigs | \
  while read line ; do \

Hi Joe,

Nice finding! The trickier point is to nicely remove them because:
1. The easiest is 'savedefconfig' but then some valuable options might disappear (like recently happened with DEBUG_FS),
2. They could be removed in automated way with a script. However in such case what about replacements? If some symbol was replaced with other (or just renamed), maybe we should enable the other one to restore the desired functionality?
3. Or maybe let's don't care about keeping defconfigs stable and just clean them up automatically.

Best regards,
Krzysztof

(...)

Feel free to pick any of these symbols and send patches for those. No need to do it one symbol at a time, but please group them like Krzysztof has done.

I don't see a good way to do it automatically. It would be good to check that we don't remove Kconfig symbols that are still used in defconfig files without changing those files as well. Cleaning up afterwards also works, but this always requires manual inspection for each symbol.

Arnd

Note that while they disappear from the defconfig, they were already not part of the build. So kernels have been built without them for a while. It's a good way to surface the problem, but it's pretty clear that trees fall in the forest here all the time and nobody is noticing.

Churning defconfigs is just noise, and a source of annoying needless conflicts when people do it at the same time. If an option is no longer in-tree, it doesn't do any harm. But it makes sense to clean up every now and then like the original patch here.

Hi Krzysztof.

There seems there are a lot more of these unused CONFIG_<foo> symbols in various defconfigs. (just for arm and treewide below)

ARM defconfigs:

--------------------------------------------------------------------

# find all defined config symbols in Kconfig files

$ git grep -P -oh '^\s*(?:menu)?config\s+\w+' -- '*/Kconfig*' | \
  sed -r -e 's/\s*config\s+//' -e 's/\s*menuconfig\s+//' | \
  sort | uniq > config_symbols

# find CONFIG_ symbols in arm defconfigs

$ git grep -w -oh -P 'CONFIG_\w+' 'arch/arm*/*defconfig*' | \
  sort | uniq > used_in_arm_defconfigs

# find all the unused symbols

$ cat used_in_arm_defconfigs | \
  while read line ; do \
    echo -n "$line " ; grep -w -c ${line/CONFIG_/} config_symbols ; \
  done | \
  grep " 0" | \
