====================
Netfilter fixes for net
The following patchset contains a large batch with Netfilter fixes for
your net tree, they are:
1) Two patches to solve conntrack garbage collector cpu hogging, one to
remove GC_MAX_EVICTS and another to look at the ratio (scanned entries
vs. evicted entries) to make a decision on whether to reduce or not
the scanning interval. From Florian Westphal.
2) Two patches to fix incorrect set element counting if NLM_F_EXCL is
is not set. Moreover, don't decrenent set->nelems from abort patch
if -ENFILE which leaks a spare slot in the set. This includes a
patch to deconstify the set walk callback to update set->ndeact.
3) Two fixes for the fwmark_reflect sysctl feature: Propagate mark to
reply packets both from nf_reject and local stack, from Pau Espin Pedrol.
4) Fix incorrect handling of loopback traffic in rpfilter and nf_tables
fib expression, from Liping Zhang.
5) Fix oops on stateful objects netlink dump, when no filter is specified.
Also from Liping Zhang.
6) Fix a build error if proc is not available in ipt_CLUSTERIP, related
to fix that was applied in the previous batch for net. From Arnd Bergmann.
7) Fix lack of string validation in table, chain, set and stateful
object names in nf_tables, from Liping Zhang. Moreover, restrict
maximum log prefix length to 127 bytes, otherwise explicitly bail
out.
8) Two patches to fix spelling and typos in nf_tables uapi header file
and Kconfig, patches from Alexander Alemayhu and William Breathitt Gray.

-Description:
- The /sys/devices/.../deferred_probe attribute is
- present for all devices. If a driver detects during
- probing a device that a related device is not yet
- ready, it may defer probing of the first device. The
- kernel will retry probing the first device after any
- other device is successfully probed. This attribute
- reads as 1 if probing of this device is currently
- deferred, or 0 otherwise.

+Page fragments
+--------------
+
+A page fragment is an arbitrary-length arbitrary-offset area of memory
+which resides within a 0 or higher order compound page. Multiple
+fragments within that page are individually refcounted, in the page's
+reference counter.
+
+The page_frag functions, page_frag_alloc and page_frag_free, provide a
+simple allocation framework for page fragments. This is used by the
+network stack and network device drivers to provide a backing region of
+memory for use as either an sk_buff->head, or to be used in the "frags"
+portion of skb_shared_info.
+
+In order to make use of the page fragment APIs a backing page fragment
+cache is needed. This provides a central point for the fragment allocation
+and tracks allows multiple calls to make use of a cached page. The
+advantage to doing this is that multiple calls to get_page can be avoided
+which can be expensive at allocation time. However due to the nature of
+this caching it is required that any calls to the cache be protected by
+either a per-cpu limitation, or a per-cpu limitation and forcing interrupts
+to be disabled when executing the fragment allocation.
+
+The network stack uses two separate caches per CPU to handle fragment
+allocation. The netdev_alloc_cache is used by callers making use of the
+__netdev_alloc_frag and __netdev_alloc_skb calls. The napi_alloc_cache is
+used by callers of the __napi_alloc_frag and __napi_alloc_skb calls. The
+main difference between these two calls is the context in which they may be
+called. The "netdev" prefixed functions are usable in any context as these
+functions will disable interrupts, while the "napi" prefixed functions are
+only usable within the softirq context.
+
+Many network device drivers use a similar methodology for allocating page
+fragments, but the page fragments are cached at the ring or descriptor
+level. In order to enable these cases it is necessary to provide a generic
+way of tearing down a page cache. For this reason __page_frag_cache_drain
+was implemented. It allows for freeing multiple references from a single
+page via a single call. The advantage to doing this is that it allows for
+cleaning up the multiple references that were added to a page in order to
+avoid calling get_page per allocation.
+
