[PATCH 2/4] ARM: exynos_defconfig: Enable NLS_UTF8 and some crypto algorithms

[Krzysztof Kozlowski]

Enable useful, but not essential components:
 - NLS_UTF8, it might be used for accessing Microsoft-FS based storages,
 - popular crypto algorithms and transformations as modules.

[PATCH 4/4] ARM: exynos_defconfig: Enable locking test options

[Krzysztof Kozlowski]

exynos_defconfig, beside serving as a reference config for Exynos-based
devices, is used by developers during regular development work.
Enabling options responsible for locking tests allows to discover bugs
in drivers and mach code earlier.

This enables:
1. Detection of sleeping in atomic sections (DEBUG_ATOMIC_SLEEP),
2. Full lockdep (DEBUG_LOCK_ALLOC and PROVE_LOCKING which makes other
   lock debug entries unneeded),
3. Detection of soft, kernel lockups (SOFTLOCKUP_DETECTOR).
