Subject: [PATCHv3 11/27] x86/vdso/Makefile: Add vobjs32
Date: Thu, 25 Apr 2019 17:14:00 +0100 [thread overview]
Message-ID: <20190425161416.26600-12-dima@arista.com> (raw)
In-Reply-To: <20190425161416.26600-1-dima@arista.com>
Treat ia32/i386 objects in array the same As for 64-bit vdso objects.
This is a preparation ground to avoid code duplication on introduction
timens vdso.
