From 56b805b33b2073776f5bdd42123670d27c898084 Mon Sep 17 00:00:00 2001 From: Olaf Hering Date: Mon, 14 May 2012 16:50:03 +0100 Subject: [PATCH] unmodified drivers: hide xen_cpuid_base() in version 2.6.38+ Allow compilation of PVonHVM drivers with forward-ported xenlinux sources in openSuSE 12.1. xen_cpuid_base() is now in mainline, the copy in the xen tree leads to a compilation error. The current state leads to a compile error: /usr/src/packages/BUILD/xen-4.2.24547/non-dbg/obj/default/platform-pci/platform-pci.c:121: error: redefinition of 'xen_cpuid_base' /usr/src/linux-3.0.13-0.11/arch/x86/include/asm/xen/hypervisor.h:43: error: previous definition of 'xen_cpuid_base' was here The reason is that the kernel sources are searched before the xen sources for asm/hypervisor.h: /usr/src/linux-3.0.13-0.11/arch/x86/include/asm/hypervisor.h /usr/src/packages/BUILD/xen-4.2.24547/non-dbg/obj/default/include/asm/hypervisor.h Signed-off-by: Olaf Hering Acked-by: Jan Beulich Committed-by: Jan Beulich xen-unstable changeset: 25067:05768bd498f2 xen-unstable date: Fri Mar 16 11:34:14 2012 +0100 --- unmodified_drivers/linux-2.6/platform-pci/platform-pci.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/unmodified_drivers/linux-2.6/platform-pci/platform-pci.c b/unmodified_drivers/linux-2.6/platform-pci/platform-pci.c index 759a0d1cae..f36179ffe5 100644 --- a/unmodified_drivers/linux-2.6/platform-pci/platform-pci.c +++ b/unmodified_drivers/linux-2.6/platform-pci/platform-pci.c @@ -118,6 +118,7 @@ unsigned long alloc_xen_mmio(unsigned long len) #ifndef __ia64__ +#if LINUX_VERSION_CODE < KERNEL_VERSION(2,6,38) static uint32_t xen_cpuid_base(void) { uint32_t base, eax, ebx, ecx, edx; @@ -136,6 +137,7 @@ static uint32_t xen_cpuid_base(void) return 0; } +#endif static int init_hypercall_stubs(void) { -- 2.39.5
