4b6cb5d8e3 [INET]: Small cleanup for xxx_put after evictor consolidation
After the evictor code is consolidated there is no need in
passing the extra pointer to the xxx_put() functions.

The only place when it made sense was the evictor code itself.

Maybe this change must got with the previous (or with the
next) patch, but I try to make them shorter as much as
possible to simplify the review (but they are still large
anyway), so this change goes in a separate patch.

8e7999c44e [INET]: Consolidate the xxx_evictor
The evictors collect some statistics for ipv4 and ipv6,
so make it return the number of evicted queues and account
them all at once in the caller.

The XXX_ADD_STATS_BH() macros are just for this case,
but maybe there are places in code, that can make use of
them as well.

1e4b82873a [INET]: Consolidate the xxx_frag_destroy
To make in possible we need to know the exact frag queue
size for inet_frags->mem management and two callbacks:

 * to destoy the skb (optional, used in conntracks only)
 * to free the queue itself (mandatory, but later I plan to
   move the allocation and the destruction of frag_queues
   into the common place, so this callback will most likely
   be optional too).

04128f233f [INET]: Collect common frag sysctl variables together
Some sysctl variables are used to tune the frag queues
management and it will be useful to work with them in
a common way in the future, so move them into one
structure, moreover they are the same for all the frag
management codes.

I don't place them in the existing inet_frags object,
introduced in the previous patch for two reasons:

 1. to keep them in the __read_mostly section;
 2. not to export the whole inet_frags objects outside.

7eb95156d9 [INET]: Collect frag queues management objects together
There are some objects that are common in all the places
which are used to keep track of frag queues, they are:

 * hash table
 * LRU list
 * rw lock
 * rnd number for hash function
 * the number of queues
 * the amount of memory occupied by queues
 * secret timer

Move all this stuff into one structure (struct inet_frags)
to make it possible use them uniformly in the future. Like
with the previous patch this mostly consists of hunks like

-    write_lock(&ipfrag_lock);
+    write_lock(&ip4_frags.lock);

To address the issue with exporting the number of queues and
the amount of memory occupied by queues outside the .c file
they are declared in, I introduce a couple of helpers.

    Date:   Wed Jul 18 21:49:10 2007 -0700

    [TG3]: Fix msi issue with kexec/kdump.

In making that change, the PCI latency timer and cache line size
registers were not restored after chip reset.  On the 5705, the
latency timer gets reset to 0 during chip reset and this causes
very poor performance.

Update version to 3.84.

861d048607 [IPV4]: Uninline netfilter okfns
Now that we don't pass double skb pointers to nf_hook_slow anymore, gcc
can generate tail calls for some of the netfilter hook okfn invocations,
so there is no need to inline the functions anymore. This caused huge
code bloat since we ended up with one inlined version and one out-of-line
version since we pass the address to nf_hook_slow.

Before:
   text    data     bss     dec     hex filename

All cases have been verified to generate tail-calls with and without

gcc can't generate tail-calls for them.

a030847e9f [NET]: Avoid copying TCP packets unnecessarily
TCP packets all have writable heads, that is, even though it's cloned, it is
writable up to the end of the TCP header.  This patch makes skb_checksum_help
aware of this fact by using skb_clone_writable and avoiding a copy for TCP.

I've also modified the BUG_ON tests to be unsigned.  The only case where this
makes a difference is if csum_start points to a location before skb->data.
Since skb->data should always include the header where the checksum field
is (and all currently callers adhere to that), this change is safe and may
uncover bugs later.

9c63d9c021 sched: sync wakeups preempt too
make sure sync wakeups preempt too - the scheduler will not
overschedule as we've got various throttles against that.
As a result, sync wakeups can be used more widely in the kernel
(to signal wakeup affinity between tasks), and no arbitrary
latencies will be introduced either.

71e20f1873 sched: affine sync wakeups
make sync wakeups affine for cache-cold tasks: if a cache-cold task
is woken up by a sync wakeup then use the opportunity to migrate it
straight away. (the two tasks are 'related' because they communicate)
