percpu: make the asm-generic/percpu.h more "generic"
- 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.)
