* 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
