Tejun Heo 9a0ef2923a s390: switch to dynamic percpu allocator ... 64bit s390 shares the same problem with alpha regarding percpu symbol addressing from modules. It needs assembly magic to force GOTENT reference when building module as the percpu address will be outside the usual 4G range from the module text. This can be solved by using weak percpu variable definitions. This patch makes s390 use weak definitions and switch to dynamic percpu allocator. Please note that weak attribute is not added if !SMP as percpu variables behave exactly the same as normal variables on UP. Compile tested. Generation of GOTENT reference verified. This patch is based on Ivan Kokshaysky's alpha percpu patch.
