f6340ee0c6 IPVS: netns, defense work timer.
This patch makes defense work timer per name-space,
A net ptr had to be added to the ipvs struct,
since it's needed by defense_work_handler.

[ horms@verge.net.au: Use cancel_delayed_work_sync() instead of
	              cancel_rearming_delayed_work(). Found during
		      merge conflict resoliution ]

6e67e586e7 IPVS: netns, connection hash got net as param.
Connection hash table is now name space aware.
i.e. net ptr >> 8 is xor:ed to the hash,
and this is the first param to be compared.
The net struct is 0xa40 in size ( a little bit smaller for 32 bit arch:s)
and cache-line aligned, so a ptr >> 5 might be a more clever solution ?

All lookups where net is compared uses net_eq() which returns 1 when netns
is disabled, and the compiler seems to do something clever in that case.

ip_vs_conn_fill_param() have *net as first param now.

Three new inlines added to keep conn struct smaller
when names space is disabled.
- ip_vs_conn_net()
- ip_vs_conn_net_set()
- ip_vs_conn_net_eq()

*v3
  moved net compare to the end in "fast path"

b17fc9963f IPVS: netns, ip_vs_stats and its procfs
The statistic counter locks for every packet are now removed,
and that statistic is now per CPU, i.e. no locks needed.
However summing is made in ip_vs_est into ip_vs_stats struct
which is moved to ipvs struc.

procfs, ip_vs_stats now have a "per cpu" count and a grand total.
A new function seq_file_single_net() in ip_vs.h created for handling of
single_open_net() since it does not place net ptr in a struct, like others.

9330419d9a IPVS: netns, use ip_vs_proto_data as param.
ip_vs_protocol *pp is replaced by ip_vs_proto_data *pd in
function call in ip_vs_protocol struct i.e. :,
 - timeout_change()
 - state_transition()

ip_vs_protocol_timeout_change() got ipvs as param, due to above
and a upcoming patch - defence work

Most of this changes are triggered by Julians comment:
"tcp_timeout_change should work with the new struct ip_vs_proto_data
        so that tcp_state_table will go to pd->state_table
        and set_tcp_state will get pd instead of pp"

*v3
Mostly comments from Julian
The pp -> pd conversion should start from functions like
ip_vs_out() that use pp = ip_vs_proto_get(iph.protocol),
now they should use ip_vs_proto_data_get(net, iph.protocol).
conn_in_get() and conn_out_get() unused param *pp, removed.

*v4
ip_vs_protocol_timeout_change() walk the proto_data path.

fc723250c9 IPVS: netns to services part 1
Services hash tables got netns ptr a hash arg,
While Real Servers (rs) has been moved to ipvs struct.
Two new inline functions added to get net ptr from skb.

Since ip_vs is called from different contexts there is two
places to dig for the net ptr skb->dev or skb->sk
this is handled in skb_net() and skb_sknet()

Global functions, ip_vs_service_get() ip_vs_lookup_real_service()
etc have got  struct net *net as first param.
If possible get net ptr skb etc,
 - if not &init_net is used at this early stage of patching.

ip_vs_ctl.c  procfs not ready for netns yet.

*v3
 Comments by Julian
- __ip_vs_service_find and __ip_vs_svc_fwm_find are fast path,
  net_eq(svc->net, net) so the check is at the end now.
- net = skb_net(skb) in ip_vs_out moved after check for skb_dst.

61b1ab4583 IPVS: netns, add basic init per netns.
Preparation for network name-space init, in this stage
some empty functions exists.

In most files there is a check if it is root ns i.e. init_net
if (!net_eq(net, &init_net))
        return ...
this will be removed by the last patch, when enabling name-space.

I've no idea why this driver uses NULL for dma_unmap_single instead of
the &spi->dev that is laying around just waiting to be used in that
function - but it's an easy fix.

Also replace this comment with a FIXME comment:
                /* Do DMA mapping "early" for better error reporting and
                 * dcache use.  Note that if dma_unmap_single() ever starts
                 * to do real work on ARM, we'd need to clean up mappings
                 * for previous transfers on *ALL* exits of this loop...
                 */
as the comment is not true - we do work in dma_unmap() functions,
particularly on ARMv6 and above.  I've corrected the existing unmap
functions but if any others are required they must be added ASAP.

735759389b spi/imx: correct the test on platform_get_irq() return value
The test "if (spi_imx->irq <= 0)" is not testing the IRQ value, but
the return value of platform_get_irq().  As platform_get_irq() can
return an error (-ENXIO) or the IRQ value it found, the test should be
"if (spi_imx->irq < 0)"

[grant.likely: Note: In general, Linux irq number 0 should also mean
no irq, but arm still allows devices to be assigned 0, and the imx
platform uses 0 for one of the spi devices, so this patch is needed
for the device to work]

root_task_group is the leftover of USER_SCHED, now it's always

But as Mike suggested, root_task_group is maybe the suitable name

So in this patch:
  init_task_group      --> root_task_group
  init_task_group_load --> root_task_group_load
  INIT_TASK_GROUP_LOAD --> ROOT_TASK_GROUP_LOAD
