Tejun Heo 9b7dbc7dc0 alpha: switch to dynamic percpu allocator ... Alpha implements custom SHIFT_PERCPU_PTR for modules because percpu area can be located far away from the 4G area where the module text is located. The custom SHIFT_PERCPU_PTR forces GOT usage using ldq instruction with literal relocation; however, the relocation can't be used with dynamically allocated percpu variables. Fortunately, similar result can be achieved by using weak percpu variable definitions. This patch makes alpha use weak definitions and switch to dynamic percpu allocator. asm/tlbflush.h was getting linux/sched.h via asm/percpu.h which no longer needs it. Include linux/sched.h directly in asm/tlbflush.h. Compile tested. Generation of litereal relocation verified. This patch is based on Ivan Kokshaysky's alpha percpu patch.
