Subject: [PATCH v5 0/6] arm64: vdso32: Address various issues
Date: Thu,  3 Oct 2019 18:48:32 +0100	[thread overview]
Message-ID: <20191003174838.8872-1-vincenzo.frascino@arm.com> (raw)

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.
