The cpufreq core is already validating the CPU frequency table after
calling the ->init() callback of the cpufreq drivers and the drivers
don't need to do the same anymore. Though they need to set the
policy->freq_table field directly from the ->init() callback now.

This is a preparatory commit to make policy->suspend_freq independent of
validation of the cpufreq table, as a later commit would update
cpufreq_generic_init() to not validate the cpufreq table any longer.

3e3b507ef6 cpufreq: tegra186: Break after initialization is done for policy->cpu
There are two clusters (2 + 4 CPUs) on this platform and a separate
cpufreq policy is available for each of the CPUs. The loop in
tegra186_cpufreq_init() tries to find the structure for the right CPU
and finish initialization. But it is missing a `break` statement at the
end, which forces it to restart the loop even when the CPU already
matched and initialization is done.

Fix that by adding the missing `break` statement.

d417e0691a cpufreq: Validate frequency table in the core
By design, cpufreq drivers are responsible for calling
cpufreq_frequency_table_cpuinfo() from their ->init()
callbacks to validate the frequency table.

However, if a cpufreq driver is buggy and fails to do so properly, it
lead to unexpected behavior of the driver or the cpufreq core at a
later point in time.  It would be better if the core could
validate the frequency table during driver initialization.

To that end, introduce cpufreq_table_validate_and_sort() and make
the cpufreq core call it right after invoking the ->init() callback
of the driver and destroy the cpufreq policy if the table is invalid.

For the time being the validation of the table happens twice, once
from the driver and then from the core.  The individual drivers will
be updated separately to drop table validation if they don't need it
for other reasons.

The frequency table is marked "sorted" or "unsorted" by the new helper
now instead of in cpufreq_table_validate_and_show(), as it should only
be done after validating the table (which the drivers won't do going
forward).

b24b6478e6 cpufreq: Reorder cpufreq_online() error code path
Ideally the de-allocation of resources should happen in the exact
opposite order in which they were allocated. It helps maintain the code
in long term, even if nothing really breaks with incorrect ordering.

That wasn't followed in cpufreq_online() and it has some
inconsistencies.  For example, the symlinks were created from within
the locked region while they are removed only after putting the locks.
Also ->exit() should have been called only after the symlinks are
removed and the lock is dropped, as that was the case when ->init()
was first called.

0373ca7483 cpufreq: s3c24xx: Fix broken s3c_cpufreq_init()
commit a307a1e6bc "cpufreq: s3c: use cpufreq_generic_init()"
accidentally broke cpufreq on s3c2410 and s3c2412.

These two platforms don't have a CPU frequency table and used to skip
calling cpufreq_table_validate_and_show() for them.  But with the
above commit, we started calling it unconditionally and that will
eventually fail as the frequency table pointer is NULL.

Fix this by calling cpufreq_table_validate_and_show() conditionally
again.

Commit 343a8d17fa (cpufreq: scpi: remove arm_big_little dependency)
changed the cpufreq driver on juno from arm_big_little to scpi.

The scpi set_target function does not call the frequency-invariance
setter function arch_set_freq_scale() like the arm_big_little set_target
function does. As a result the task scheduler load and utilization
signals are not frequency-invariant on this platform anymore.

Fix this by adding a call to arch_set_freq_scale() into
scpi_cpufreq_set_target().

  There was a deadlock between one thread trying to wait for a workqueue
  job to finish in the runtime suspend path, and the workqueue job it
  was waiting for in turn waiting for a runtime_get_sync to return.

  The fixes avoids it by not doing the runtime sync in the workqueue as

d903ec7711 gianfar: simplify FCS handling and fix memory leak
Previously, buffer descriptors containing only the frame check sequence
(FCS) were skipped and not added to the skb. However, the page reference
count was still incremented, leading to a memory leak.

Fixing this inside gfar_add_rx_frag() is difficult due to reserved
memory handling and page reuse. Instead, move the FCS handling to
gfar_process_frame() and trim off the FCS before passing the skb up the
networking stack.

Commit d02fd6e7d2 ("macvlan: Fix one possible double free") handles
the case when register_netdevice() invokes ndo_uninit() on error and
as a result free the port. But 'macvlan_port_get_rtnl(dev))' check
(returns dev->rx_handler_data), which was added by this commit in order
to prevent double free, is not quite correct:

* for macvlan it always returns NULL because 'lowerdev' is the one that
  was used to register rx handler (port) in macvlan_port_create() as
  well as to unregister it in macvlan_port_destroy().
* for macvtap it always returns a valid pointer because macvtap registers
  its own rx handler before macvlan_common_newlink().

Merge tag 'mac80211-for-davem-2018-02-22' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211

Johannes Berg says:

====================
Various fixes across the tree, the shortlog basically says it all:

  cfg80211: fix cfg80211_beacon_dup
  -> old bug in this code

  cfg80211: clear wep keys after disconnection
  -> certain ways of disconnecting left the keys

  mac80211: round IEEE80211_TX_STATUS_HEADROOM up to multiple of 4
  -> alignment issues with using 14 bytes

  mac80211: Do not disconnect on invalid operating class
  -> if the AP has a bogus operating class, let it be

  mac80211: Fix sending ADDBA response for an ongoing session
  -> don't send the same frame twice

  cfg80211: use only 1Mbps for basic rates in mesh
  -> interop issue with old versions of our code

  mac80211_hwsim: don't use WQ_MEM_RECLAIM
  -> it causes splats because it flushes work on a non-reclaim WQ

  regulatory: add NUL to request alpha2
  -> nla_put_string() issue from Kees

  mac80211: mesh: fix wrong mesh TTL offset calculation
  -> protocol issue

  mac80211: fix a possible leak of station stats
  -> error path might leak memory

  mac80211: fix calling sleeping function in atomic context
  -> percpu allocations need to be made with gfp flags

Here are a number of USB fixes for 4.16-rc3
 
 Nothing major, but a number of different fixes all over the place in the
 USB stack for reported issues.  Mostly gadget driver fixes, although the
 typical set of xhci bugfixes are there, along with some new quirks
 additions as well.
 
 All of these have been in linux-next for a while with no reported

Pull rdma fixes from Doug Ledford:
 "Nothing in this is overly interesting, it's mostly your garden variety
  fixes.

  There was some work in this merge cycle around the new ioctl kABI, so
  there are fixes in here related to that (probably with more to come).

  We've also recently added new netlink support with a goal of moving
  the primary means of configuring the entire subsystem to netlink
  (eventually, this is a long term project), so there are fixes for
  that.

  Then a few bnxt_re driver fixes, and a few minor WARN_ON removals, and
  that covers this pull request. There are already a few more fixes on
  the list as of this morning, so there will certainly be more to come
  in this rc cycle ;-)

  Summary:

   - Lots of fixes for the new IOCTL interface and general uverbs flow.
     Found through testing and syzkaller

   - Bugfixes for the new resource track netlink reporting

   - Remove some unneeded WARN_ONs that were triggering for some users

AFAIK the only version of smc9194.c with Mac support is the one in the

Despite that, from v2.3.45, arch/m68k/config.in listed CONFIG_SMC9194
under CONFIG_MAC. This mistake got carried over into Kconfig in v2.5.55.
