From f880b67dcbdedb49453f88d2ccb1a0937b046d82 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 9 Oct 2012 10:33:52 +0000 Subject: ARM: Xen: fix initial build problems * The XEN_BALLOON code requires the balloon infrastructure that is not getting built on ARM. * The tmem hypercall is not available on ARM * ARMv6 does not support cmpxchg on 16-bit words that are used in the Xen grant table code, so we must ensure that Xen support is only built on ARMv7-only kernels not combined ARMv6/v7 kernels. * sys-hypervisor.c needs to include linux/err.h in order to use the IS_ERR/PTR_ERR/ERR_PTR family of functions.
