UPSTREAM: netfilter: x_tables: pack percpu counter allocations instead of allocating each xt_counter individually, allocate 4k chunks and then use these for counter allocation requests. This should speed up rule evaluation by increasing data locality, also speeds up ruleset loading because we reduce calls to the percpu allocator. As Eric points out we can't use PAGE_SIZE, page_allocator would fail on arches with 64k page size. BUG=b:34936410 BUG=chromium:689152 TEST=Booted an image with this patch and verified iptables-restore performance improvement.
