Subject: [PATCH v6 09/19] lib: vdso: Add compat support
Date:   Thu, 30 May 2019 15:15:21 +0100
Message-Id: <20190530141531.43462-10-vincenzo.frascino@arm.com>

Precedence: bulk

Some 64 bit architectures have support for 32 bit applications that
require a separate version of the vDSOs.

Add support to the generic code for compat fallback functions.
