====================
Increase the limit of tuntap queues
Networking under KVM works best if we allocate a per-vCPU rx and tx
queue in a virtual NIC. This requires a per-vCPU queue on the host side.
Modern physical NICs have multiqueue support for large number of queues.

PATCH 1: Sergei Shtylyov - Add an empty line after declarations.
PATCH 2: Jiri Pirko - Do not introduce new module paramaters.
Michael.S.Tsirkin- We can use sysctl for limiting max number

This series is to increase the number of tuntap queues. Original work is being
done by 'jasowang@redhat.com'. I am taking this 'https://lkml.org/lkml/2013/6/19/29'
patch series as a reference. As per discussion in the patch series:
There were two reasons which prevented us from increasing number of tun queues:
- The netdev_queue array in netdevice were allocated through kmalloc, which may
cause a high order memory allocation too when we have several queues.
E.g. sizeof(netdev_queue) is 320, which means a high order allocation would
happens when the device has more than 16 queues.
- We store the hash buckets in tun_struct which results a very large size of
tun_struct, this high order memory allocation fail easily when the memory is
fragmented.
The patch
60877a32bce00041528576e6b8df5abe9251fa73 increases the number of tx
queues. Memory allocation fallback to vzalloc() when kmalloc() fails.
This series tries to address following issues:
- Increase the number of netdev_queue queues for rx similarly its done for tx
queues by falling back to vzalloc() when memory allocation with kmalloc() fails.
- Increase number of queues to 256, maximum number is equal to maximum number
of vCPUS allowed in a guest.
I have also done testing with multiple parallel Netperf sessions for different
combination of queues and CPU's. It seems to be working fine without much increase
in cpu load with increase in number of queues. I also see good increase in throughput
with increase in number of queues. Though i had limitation of 8 physical CPU's.
For this test: Two Hosts(Host1 & Host2) are directly connected with cable
Host1 is running Guest1. Data is sent from Host2 to Guest1 via Host1.

netif_alloc_rx_queues() uses kcalloc() to allocate memory

Similar implementation is done for tx queue allocation in
netif_alloc_netdev_queues().
We avoid failure of high order memory allocation
with the help of vzalloc(), this allows us to do large
rx and tx queue allocation which in turn helps us to

bonding: cleanup bond_opts array
Remove the empty array element initializer and size the array with

An interesting unwanted side effect of this initializer is that if one
inserts new options into the middle of the array then this initializer
will zero out the option that equals BOND_OPT_TLB_DYNAMIC_LB+1.
Example:
Extend the OPTS enum:
enum {
...
BOND_OPT_TLB_DYNAMIC_LB,
BOND_OPT_LACP_NEW1,
BOND_OPT_LAST
};
Now insert into bond_opts array:
static const struct bond_option bond_opts[] = {
...
[BOND_OPT_LACP_RATE] = { .... unchanged stuff .... },
[BOND_OPT_LACP_NEW1] = { ... new stuff ... },
...
[BOND_OPT_TLB_DYNAMIC_LB] = { .... unchanged stuff ....},
{ } // MARK A

Ying Xue says:
====================
tipc: make tipc support namespace
This patchset aims to add net namespace support for TIPC stack.
Currently TIPC module declares the following global resources:
- TIPC network idenfication number
- TIPC node table
- TIPC bearer list table
- TIPC broadcast link
- TIPC socket reference table
- TIPC name service table
- TIPC node address
- TIPC service subscriber server
- TIPC random value
- TIPC netlink
In order that TIPC is aware of namespace, above each resource must be
allocated, initialized and destroyed inside per namespace. Therefore,
the major works of this patchset are to isolate these global resources
and make them private for each namespace. However, before these changes
come true, some necessary preparation works must be first done: convert
socket reference table with generic rhashtable, cleanup core.c and
core.h files, remove unnecessary wrapper functions for kernel timer
interfaces and so on.
It should be noted that commit ##1 ("tipc: fix bug in broadcast
retransmit code") was already submitted to 'net' tree, so please see
below link:
http://patchwork.ozlabs.org/patch/426717/
Since it is prerequisite for the rest of the series to apply, I
prepend them to the series.

tipc: feed tipc sock pointer to tipc_sk_timeout routine
In order to make tipc socket table aware of namespace, a networking
namespace instance must be passed to tipc_sk_lookup(), allowing it
to look up tipc socket instance with a given port ID from a concrete
socket table. However, as now tipc_sk_timeout() only has one port ID
parameter and is not namespace aware, it's unable to obtain a correct
socket instance through tipc_sk_lookup() just with a port ID,
especially after namespace is completely supported.
If port ID is replaced with socket instance as tipc_sk_timeout()'s
parameter, it's unnecessary to look up socket table. But as the timer
handler - tipc_sk_timeout() is run asynchronously, socket reference
must be held before its timer is launched, and must be carefully
checked to identify whether the socket reference needs to be put or
not when its timer is terminated.

tipc: fix bug in broadcast retransmit code
In commit
58dc55f25631178ee74cd27185956a8f7dcb3e32 ("tipc: use generic
SKB list APIs to manage link transmission queue") we replace all list
traversal loops with the macros skb_queue_walk() or
skb_queue_walk_safe(). While the previous loops were based on the
assumption that the list was NULL-terminated, the standard macros
stop when the iterator reaches the list head, which is non-NULL.
In the function bclink_retransmit_pkt() this macro replacement has
lead to a bug. When we receive a BCAST STATE_MSG we unconditionally
call the function bclink_retransmit_pkt(), whether there really is
anything to retransmit or not, assuming that the sequence number
comparisons will lead to the correct behavior. However, if the
transmission queue is empty, or if there are no eligible buffers in
the transmission queue, we will by mistake pass the list head pointer
to the function tipc_link_retransmit(). Since the list head is not a
valid sk_buff, this leads to a crash.
In this commit we fix this by only calling tipc_link_retransmit()
if we actually found eligible buffers in the transmission queue.

====================
Fix sti drivers whcih mix reg address spaces
A V2 of this old series incorporating Arnd and Lees Feedback form v1.
Following on from Arnds comments about the picophy driver here
https://lkml.org/lkml/2014/11/13/161, this series fixes the
remaining upstreamed drivers for STI, which are mixing address spaces
in the reg property. We do this in a way similar to the keystone
and bcm7445 platforms, by having sysconfig phandle/ offset pair
(where only one register is required). Or phandle / integer array
where multiple offsets in the same bank are needed).
This series breaks DT compatability! But the platform support
is WIP and only being used by the few developers who are upstreaming
support for it. I've made each change to the driver / dt doc / dt
file as a single atomic commit so the kernel will remain bisectable.
This series then also enables the picophy driver, and adds back in
the ehci/ohci dt nodes for stih410 which make use of the picophy.

====================
Involve rhashtable_lookup_insert routine
The series aims to involve rhashtable_lookup_insert() to guarantee
that the process of lookup and insertion of an object from/into hash
table is finished atomically, allowing rhashtable's users not to
introduce an extra lock during search and insertion. For example,
tipc socket is the first user benefiting from this enhancement.
v2 changes:
- fix the issue of waking up worker thread under a wrong condition in
patch #2, which is pointed by Thomas.
- move a comment from rhashtable_inser() to rhashtable_wakeup_worker()
according to Thomas's suggestion in patch #2.
- indent the third line of condition statement in
rhashtable_wakeup_worker() to inner bracket in patch #2.
- drop patch #3 of v1 series
- fix an issue of being unable to remove an object from hash table in
certain special case in patch #4.
- involve a new patch #5 to avoid unnecessary wakeup for worker queue
thread
- involve a new patch #6 to initialize atomic "nelems" variable
- adjust "nelem_hint" value from 256 to 192 avoiding to unnecessarily
to shrink hash table from the beginning phase in patch #7.
v1 changes:
But before rhashtable_lookup_insert() is involved, the following
optimizations need to be first done:
- simplify rhashtable_lookup by reusing rhashtable_lookup_compare()
- introduce rhashtable_wakeup_worker() to further reduce duplicated
code in patch #2
- fix an issue in patch #3
- involve rhashtable_lookup_insert(). But in this version, we firstly
use rhashtable_lookup() to search duplicate key in both old and new
bucket table; secondly introduce another __rhashtable_insert() helper
function to reduce the duplicated code between rhashtable_insert()
and rhashtable_lookup_insert().
- add patch #5 into the series as it depends on above patches. But in
this version, no change is made comparing with its previous version.

tipc: convert tipc reference table to use generic rhashtable
As tipc reference table is statically allocated, its memory size
requested on stack initialization stage is quite big even if the
maximum port number is just restricted to 8191 currently, however,
the number already becomes insufficient in practice. But if the
maximum ports is allowed to its theory value - 2^32, its consumed
memory size will reach a ridiculously unacceptable value. Apart from
this, heavy tipc users spend a considerable amount of time in
tipc_sk_get() due to the read-lock on ref_table_lock.
If tipc reference table is converted with generic rhashtable, above
mentioned both disadvantages would be resolved respectively: making
use of the new resizable hash table can avoid locking on the lookup;
smaller memory size is required at initial stage, for example, 256
hash bucket slots are requested at the beginning phase instead of
allocating the entire 8191 slots in old mode. The hash table will
grow if entries exceeds 75% of table size up to a total table size
of 1M, and it will automatically shrink if usage falls below 30%,
but the minimum table size is allowed down to 256.
Also converts ref_table_lock to a separate mutex to protect hash table
mutations on write side. Lastly defers the release of the socket
reference using call_rcu() to allow using an RCU read-side protected
call to rhashtable_lookup().
