Subject: [PATCH 5/6] Cleanup header files to build a proper 32 bit VDSO

From: Stefani Seibold <stefani@...bold.net>

To build a proper VDSO for 64 bit and 32 bit from the same source, some
header cleanup is necessary, otherwise a "gcc -m32" will produce a lot
of errors and warnings due the differents with LP64 and LP32.
