Pull power management fixes from Rafael Wysocki:
 "One of these is an intel_pstate regression fix and it is not a small
  change, but it mostly removes code that shouldn't be there. That code
  was acquired by mistake and has been a source of constant pain since
  then, so the time has come to get rid of it finally. We have not seen
  problems with this change in the lab, so fingers crossed.

  The rest is more usual: one more intel_pstate commit removing useless
  code, a cpufreq core fix to make it restore policy limits on CPU
  online (which prevents the limits from being reset over system
  suspend/resume), a schedutil cpufreq governor initialization fix to
  make it actually work as advertised on all systems and an extra sanity
  check in the cpuidle core to prevent crashes from happening if the
  arch code messes things up.

  Specifics:

   - Make intel_pstate use one set of global P-state limits in the
     active mode regardless of the scaling_governor settings for
     individual CPUs instead of switching back and forth between two of
     them in a way that is hard to control (Rafael Wysocki).

   - Drop a useless function from intel_pstate to prevent it from
     modifying the maximum supported frequency value unexpectedly which
     may confuse the cpufreq core (Rafael Wysocki).

   - Fix the cpufreq core to restore policy limits on CPU online so that
     the limits are not reset over system suspend/resume, among other
     things (Viresh Kumar).

   - Fix the initialization of the schedutil cpufreq governor to make
     the IO-wait boosting mechanism in it actually work on systems with
     one CPU per cpufreq policy (Rafael Wysocki).

   - Add a sanity check to the cpuidle core to prevent crashes from
     happening if the architecture code initialization fails to set up
     things as expected (Vaidyanathan Srinivasan)"

compile-testing fails when QCOM_SMD is a loadable module:

drivers/bluetooth/built-in.o: In function `btqcomsmd_send':
btqca.c:(.text+0xa8): undefined reference to `qcom_smd_send'
drivers/bluetooth/built-in.o: In function `btqcomsmd_probe':
btqca.c:(.text+0x3ec): undefined reference to `qcom_wcnss_open_channel'
btqca.c:(.text+0x46c): undefined reference to `qcom_smd_set_drvdata'

This clarifies the dependency to allow compile-testing only when
SMD is completely disabled, otherwise the dependency on QCOM_SMD
will make sure we can link against it.

Dmitry reported a lockdep splat [1] (false positive) that we can fix
by releasing the spinlock before calling icmp_send() from ip_expire()

This is a false positive because sending an ICMP message can not
possibly re-enter the IP frag engine.

This subtle change cause that on retry ctrl_dumpfamily() call we omit
one family that failed to do ctrl_fill_info() on previous call, because
cb->args[0] = n number counts also family that failed to do
ctrl_fill_info().

Patch fixes the problem and avoid confusion in the future just decrease
n counter when ctrl_fill_info() fail.

User visible problem caused by this bug is failure to get access to
some genetlink family i.e. nl80211. However problem is reproducible
only if number of registered genetlink families is big enough to
cause second call of ctrl_dumpfamily().

In sk_clone_lock(), we create a new socket and inherit most of the
parent's members via sock_copy() which memcpy()'s various sections.
Now, in case the parent socket had a BPF socket filter attached,
then newsk->sk_filter points to the same instance as the original
sk->sk_filter.

sk_filter_charge() is then called on the newsk->sk_filter to take a
reference and should that fail due to hitting max optmem, we bail
out and release the newsk instance.

The issue is that commit 278571ba ("net: filter: simplify socket
charging") wrongly combined the dismantle path with the failure path
of xfrm_sk_clone_policy(). This means, even when charging failed, we
call sk_free_unlock_clone() on the newsk, which then still points to
the same sk_filter as the original sk.

Thus, sk_free_unlock_clone() calls into __sk_destruct() eventually
where it tests for present sk_filter and calls sk_filter_uncharge()
on it, which potentially lets sk_omem_alloc wrap around and releases
the eBPF prog and sk_filter structure from the (still intact) parent.

Fix it by making sure that when sk_filter_charge() failed, we reset
newsk->sk_filter back to NULL before passing to sk_free_unlock_clone(),
so that we don't mess with the parents sk_filter.

Only if xfrm_sk_clone_policy() fails, we did reach the point where
either the parent's filter was NULL and as a result newsk's as well
or where we previously had a successful sk_filter_charge(), thus for
that case, we do need sk_filter_uncharge() to release the prior taken
reference on sk_filter.

In both kmalloc and prealloc mode the bpf_map_update_elem() is using
per-cpu extra_elems to do atomic update when the map is full.
There are two issues with it. The logic can be misused, since it allows
max_entries+num_cpus elements to be present in the map. And alloc_extra_elems()
at map creation time can fail percpu alloc for large map values with a warn:
WARNING: CPU: 3 PID: 2752 at ../mm/percpu.c:892 pcpu_alloc+0x119/0xa60
illegal size (32824) or align (8) for percpu allocation

The fixes for both of these issues are different for kmalloc and prealloc modes.
For prealloc mode allocate extra num_possible_cpus elements and store
their pointers into extra_elems array instead of actual elements.
Hence we can use these hidden(spare) elements not only when the map is full
but during bpf_map_update_elem() that replaces existing element too.
That also improves performance, since pcpu_freelist_pop/push is avoided.
Unfortunately this approach cannot be used for kmalloc mode which needs
to kfree elements after rcu grace period. Therefore switch it back to normal
kmalloc even when full and old element exists like it was prior to
commit 6c905981 ("bpf: pre-allocate hash map elements").

Add tests to check for over max_entries and large map values.

Commit 6ac3ce82 ("net: bcmgenet: Remove excessive PHY reset")
removed the bcmgenet_mii_reset() function from bcmgenet_power_up() and
bcmgenet_internal_phy_setup() functions.  In so doing it broke the reset
of the internal PHY devices used by the GENETv1-GENETv3 which required
this reset before the UniMAC was enabled.  It also broke the internal
GPHY devices used by the GENETv4 because the config_init that installed
the AFE workaround was no longer occurring after the reset of the GPHY
performed by bcmgenet_phy_power_set() in bcmgenet_internal_phy_setup().
In addition the code in bcmgenet_internal_phy_setup() related to the
"enable APD" comment goes with the bcmgenet_mii_reset() so it should
have also been removed.

Commit bd4060a6 ("net: bcmgenet: Power on integrated GPHY in
bcmgenet_power_up()") moved the bcmgenet_phy_power_set() call to the
bcmgenet_power_up() function, but failed to remove it from the
bcmgenet_internal_phy_setup() function.  Had it done so, the
bcmgenet_internal_phy_setup() function would have been empty and could
have been removed at that time.

Commit 5dbebbb4 ("net: bcmgenet: Software reset EPHY after power on")
was submitted to correct the functional problems introduced by
commit 6ac3ce82 ("net: bcmgenet: Remove excessive PHY reset"). It
was included in v4.4 and made available on 4.3-stable. Unfortunately,
it didn't fully revert the commit because this bcmgenet_mii_reset()
doesn't apply the soft reset to the internal GPHY used by GENETv4 like
the previous one did. This prevents the restoration of the AFE work-
arounds for internal GPHY devices after the bcmgenet_phy_power_set() in
bcmgenet_internal_phy_setup().

This commit takes the alternate approach of removing the unnecessary
bcmgenet_internal_phy_setup() function which shouldn't have been in v4.3
so that when bcmgenet_mii_reset() was restored it should have only gone
into bcmgenet_power_up().  This will avoid the problems while also
removing the redundancy (and hopefully some of the confusion).

This was added to allow the TC offloading code to identify offloading
encap/decap vxlan rules.

The VF reps are effectively related to the same mlx5 PCI device as the
PF. Since the kernel invokes the (say) delete ndo for each netdev, the
FW erred on multiple vxlan dst port deletes when the port was deleted
from the system.

We fix that by keeping the registration to be carried out only by the
PF. Since the PF serves as the uplink device, the VF reps will look
up a port there and realize if they are ok to offload that.

Tested:
 <SETUP VFS>
 <SETUP switchdev mode to have representors>
 ip link add vxlan1 type vxlan id 44 dev ens5f0 dstport 9999

In this commit, we advance the calling of tipc_nametbl_unsubscribe()
from the refcount cleanup to the intended callers.

sctp_stream_free uses struct sctp_stream as a param, but struct sctp_stream
is defined after it's declaration.

This patch is to declare struct sctp_stream before sctp_stream_free.

With posix timers having become optional, we get a build error with
the cpts time sync option of the CPSW driver:

drivers/net/ethernet/ti/cpts.c: In function 'cpts_find_ts':
drivers/net/ethernet/ti/cpts.c:291:23: error: implicit declaration of function 'ptp_classify_raw';did you mean 'ptp_classifier_init'? [-Werror=implicit-function-declaration]

This adds a hard dependency on PTP_CLOCK to avoid the problem, as
building it without PTP support makes no sense anyway.

The dependency is reversed: cpsw and netcp call into cpts,
but cpts depends on the other two in Kconfig. This can lead
to cpts being a loadable module and its callers built-in:

drivers/net/ethernet/ti/cpsw.o: In function `cpsw_remove':
cpsw.c:(.text.cpsw_remove+0xd0): undefined reference to `cpts_release'
drivers/net/ethernet/ti/cpsw.o: In function `cpsw_rx_handler':
cpsw.c:(.text.cpsw_rx_handler+0x2dc): undefined reference to `cpts_rx_timestamp'
drivers/net/ethernet/ti/cpsw.o: In function `cpsw_tx_handler':
cpsw.c:(.text.cpsw_tx_handler+0x7c): undefined reference to `cpts_tx_timestamp'
drivers/net/ethernet/ti/cpsw.o: In function `cpsw_ndo_stop':

As a workaround, I'm introducing another Kconfig symbol to
control the compilation of cpts, while making the actual
module controlled by a silent symbol that is =y when necessary.

====================
r8152: fix the rx settings of RTL8153

The RMS and the rx early size should base on the same rx size. However,
the RMS is set to 9K bytes now and the rx early depends on mtu. For using
the rx buffer effectively, sync the two settings according to the mtu.
