> Add __percpu sparse annotations to net.
> These annotations are to make sparse consider percpu variables to be
> in a different address space and warn if accessed without going
> through percpu accessors. This patch doesn't affect normal builds.
> The macro and type tricks around snmp stats make things a bit
> interesting. DEFINE/DECLARE_SNMP_STAT() macros mark the target field
> as __percpu and SNMP_UPD_PO_STATS() macro is updated accordingly. All
> snmp_mib_*() users which used to cast the argument to (void **) are
> updated to cast it to (void __percpu **).
