- add support for PER_CPU_ATTRIBUTES - fix generic smp percpu_modcopy to use per_cpu_offset() macro. Add the ability to use generic/percpu even if the arch needs to override several aspects of its operations. This will enable the use of generic percpu.h for all arches. An arch may define: __per_cpu_offset Do not use the generic pointer array. Arch must define per_cpu_offset(cpu) (used by x86_64, s390). __my_cpu_offset Can be defined to provide an optimized way to determine the offset for variables of the currently executing processor. Used by ia64, x86_64, x86_32, sparc64, s/390. SHIFT_PTR(ptr, offset) If an arch defines it then special handling of pointer arithmentic may be implemented. Used by s/390. (Some of these special percpu arch implementations may be later consolidated so that there are less cases to deal with.)
