Samsung defconfig changes for v4.14
1. Enable some drivers useful on our boards (communication: Bluetooth,
WiFi, NFC, USB; codepages and crypto algorithms).
2. Enable debugging and lock testing options. These might have impact on
performance but we use the exynos_defconfig a lot during development
so they should bring benefits of detecting early locking issues.
ARM: exynos_defconfig: Enable locking test options
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).
