[PATCH v5 0/6] arm64: vdso32: Address various issues

[Vincenzo Frascino]

This patch series is meant to address the various compilation issues
reported recently for arm64 vdso32 [1].

>From v4, the series contains a cleanup of lib/vdso Kconfig as well since
CROSS_COMPILE_COMPAT_VDSO is not required anymore by any architecture.
