813f020c5d rtnetlink: remove check for fill_slave_info in rtnl_have_link_slave_info
This check is not needed because the same check is done before
fill_slave_info is used in rtnl_link_slave_info_fill.
Also, by removing this check, kernel will fillup IFLA_INFO_SLAVE_KIND
even for slaves of masters which does not implement fill_slave_info.

  Decoupled logic in the code which was using same call to

  during set_channel() operation for TSS/RSS. This refactoring
  simplifies code for TSS/RSS code path as well as probe path

d9317aea16 sfc: Use the correct maximum TX DMA ring size for SFC9100
As part of a workaround for a hardware erratum in the SFC9100 family
(SF bug 35388), the TX_DESC_UPD_DWORD register address is also used
for communicating with the event block, and only descriptor pointer
values < 2048 are valid.

If the TX DMA ring size is increased to 4096 descriptors (which the
firmware still allows) then we may write a descriptor pointer
value >= 2048, which has entirely different and undesirable effects!

Limit the TX DMA ring size correctly when this workaround is in
effect.

But commit 0e6fbc5b6c621("ip_tunnels: extend iptunnel_xmit()") refactor codes,
and it clear IPCB behind the dst_link_failure().

9fe6cb5837 net/cxgb4: Don't retrieve stats during recovery
We possibly retrieve the adapter's statistics during EEH recovery
and that should be disallowed. Otherwise, it would possibly incur
replicate EEH error and EEH recovery is going to fail eventually.

The patch reuses statistics lock and checks net_device is attached
before going to retrieve statistics, so that the problem can be
avoided.

144be3d9f7 net/cxgb4: Avoid disabling PCI device for towice
If we have EEH error happens to the adapter and we have to remove
it from the system for some reasons (e.g. more than 5 EEH errors
detected from the device in last hour), the adapter will be disabled
for towice separately by eeh_err_detected() and remove_one(), which
will incur following unexpected backtrace. The patch tries to avoid
it.

6ef7b8a23a net: Correctly sync addresses from multiple sources to single device
When we have multiple devices attempting to sync the same address
to a single destination, each device should be permitted to sync
it once.  To accomplish this, pass the 'sync_cnt' of the source
address when adding the addresss to the lower device.  'sync_cnt'
tracks how many time a given address has been succefully synced.
This way, we know that if the 'sync_cnt' passed in is 0, we should
sync this address.

Also, turn 'synced' member back into the counter as was originally
done in
   commit 4543fbefe6.
   net: count hw_addr syncs so that unsync works properly.
It tracks how many time a given address has been added via a
'sync' operation.  For every successfull 'sync' the counter is
incremented, and for ever 'unsync', the counter is decremented.
This makes sure that the address will be properly removed from
the the lower device when all the upper devices have removed it.

3ad88cf70a tcp: metrics: Handle v6/v4-mapped sockets in tcp-metrics
A socket may be v6/v4-mapped. In that case sk->sk_family is AF_INET6,
but the IP being used is actually an IPv4-address.
Current's tcp-metrics will thus represent it as an IPv6-address:

root@server:~# ip tcp_metrics
::ffff:10.1.1.2 age 22.920sec rtt 18750us rttvar 15000us cwnd 10
10.1.1.2 age 47.970sec rtt 16250us rttvar 10000us cwnd 10

This patch modifies the tcp-metrics so that they are able to handle the
v6/v4-mapped sockets correctly.

4afc81cd1c perf symbols: Load map before using map->map_ip()
In map_groups__find_symbol() map->map_ip is used without ensuring the
map is loaded. Then the address passed to map->map_ip isn't mapped at
the first time.

E.g. below code always fails to get a symbol at the first call;

	addr = /* Somewhere in the kernel text */
	symbol_conf.try_vmlinux_path = true;
	symbol__init();
	host_machine = machine__new_host();
	sym = machine__find_kernel_function(host_machine,
					 addr, NULL, NULL);
	/* Note that machine__find_kernel_function calls
	   map_groups__find_symbol */

This ensures it by calling map__load before using it in
map_groups__find_symbol().

b935a58dbf perf tools: Fix traceevent plugin path definitions
The plugindir_SQ definition contains $(prefix) which is not needed as
the $(libdir) definition already contains prefix in it.  This leads to
the path including an extra prefix in it, e.g. /usr/usr/lib64.

The -DPLUGIN_DIR defintion includes DESTDIR.  This is incorrect, as it
sets the plugin search path to include the value of DESTDIR.  DESTDIR is
a mechanism to install in a non-standard location such as a chroot or an
RPM build root.  In the RPM case, this leads to the search path being
incorrect after the resulting RPM is installed (or in some cases an RPM
build failure).

Remove both of these unnecessary inclusions.

d375b4e0fa sched/clock: Fixup early initialization
The code would assume sched_clock_stable() and switch to !stable
later, this switch brings a discontinuity in time.

The discontinuity on switching from stable to unstable was always
present, but previously we would set stable/unstable before
initializing TSC and usually stick to the one we start out with.

So the static_key bits brought an extra switch where there previously
wasn't one.

Things are further complicated by the fact that we cannot use
static_key as early as we usually call set_sched_clock_stable().

Fix things by tracking the stable state in a regular variable and only
set the static_key to the right state on sched_clock_init(), which is
ran right after late_time_init->tsc_init().

Before this we would not be using the TSC anyway.

This reverts commit 282cf499f0.

With the current implementation, the load average statistics of a sched entity
change according to other activity on the CPU even if this activity is done
between the running window of the sched entity and have no influence on the
running duration of the task.

When a task wakes up on the same CPU, we currently update last_runnable_update
with the return  of __synchronize_entity_decay without updating the
runnable_avg_sum and runnable_avg_period accordingly. In fact, we have to sync
the load_contrib of the se with the rq's blocked_load_contrib before removing
it from the latter (with __synchronize_entity_decay) but we must keep
last_runnable_update unchanged for updating runnable_avg_sum/period during the
next update_entity_load_avg.
