Date: Mon, 11 Feb 2008 14:38:51 -0800 (PST) From: Roland McGrath <roland@...hat.com> To: Ingo Molnar <mingo@...e.hu>, Thomas Gleixner <tglx@...utronix.de> Cc: Kyle McMartin <kyle@...artin.ca> Subject: [PATCH 2.6.25] x86: vdso_install fix The makefile magic for installing the 32-bit vdso images on disk had a little error. Only one line of change would fix that bug. This does a little more to reduce the error-prone duplication of this bit of makefile variable magic.
