Here is a patch which should fix this problem. I will run a few more tests and then push it with the rest of the urgent queue to Linus. -hpa -- H. Peter Anvin, Intel Open Source Technology Center I work for Intel. I don't speak on their behalf.
>From 497e064320506cd15f7bdd659204b576c80bf24e Mon Sep 17 00:00:00 2001 From: "H. Peter Anvin" <hpa@xxxxxxxxx> Date: Thu, 19 Jan 2012 12:41:25 -0800 Subject: [PATCH] x86, syscall: Need __ARCH_WANT_SYS_IPC for 32 bits In checkin 303395ac3bf3 x86: Generate system call tables and unistd_*.h from tables the feature macros in <asm/unistd.h> were unified between 32 and 64 bits. Unfortunately 32 bits requires __ARCH_WANT_SYS_IPC and this was inadvertently dropped.
