percpu: unbreak alpha percpu
Tejun Heo [Fri, 10 Apr 2009 19:02:40 +0000 (12:02 -0700)]
For the time being, move the generic percpu_*() accessors to
linux/percpu.h.

asm-generic/percpu.h is meant to carry generic stuff for low level
stuff - declarations, definitions and pointer offset calculation
and so on but not for generic interface.
