Arnd Bergmann 6214f5c966 x86/xen: add CPU dependencies for 32-bit build ... [ Upstream commit 93cd059764 ] Xen only supports modern CPUs even when running a 32-bit kernel, and it now requires a kernel built for a 64 byte (or larger) cache line: In file included from <command-line>: In function 'xen_vcpu_setup', inlined from 'xen_vcpu_setup_restore' at arch/x86/xen/enlighten.c:111:3, inlined from 'xen_vcpu_restore' at arch/x86/xen/enlighten.c:141:3: include/linux/compiler_types.h:435:45: error: call to '__compiletime_assert_287' declared with attribute error: BUILD_BUG_ON failed: sizeof(*vcpup) > SMP_CACHE_BYTES arch/x86/xen/enlighten.c:166:9: note: in expansion of macro 'BUILD_BUG_ON' 166 | BUILD_BUG_ON(sizeof(*vcpup) > SMP_CACHE_BYTES); | ^~~~~~~~~~~~ Enforce the dependency with a whitelist of CPU configurations. In normal distro kernels, CONFIG_X86_GENERIC is enabled, and this works fine. When this is not set, still allow Xen to be built on kernels that target a 64-bit capable CPU.
