Subject: [PATCH v5 12/23] lib: vdso: Add compat support
Date: Fri, 22 Feb 2019 12:24:19 +0000 [thread overview]
Message-ID: <20190222122430.21180-13-vincenzo.frascino@arm.com> (raw)
In-Reply-To: <20190222122430.21180-1-vincenzo.frascino@arm.com>
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.
