Merge git://git.kernel.org/pub/scm/linux/kernel/git/x86/linux-2.6-x86
* git://git.kernel.org/pub/scm/linux/kernel/git/x86/linux-2.6-x86: alpha: fix x86.git merge build error ia64: on UP percpu variables are not small memory model x86: fix arch/x86/kernel/test_nx.c modular build bug s390: use generic percpu linux-2.6.git POWERPC: use generic per cpu ia64: use generic percpu SPARC64: use generic percpu percpu: change Kconfig to HAVE_SETUP_PER_CPU_AREA modules: fold percpu_modcopy into module.c x86: export copy_from_user_ll_nocache[_nozero] x86: fix duplicated TIF on 64-bit
