Commit 8c0d3a02 ("PCI: Add accessors for PCI Express Capability")
added accessors for the PCI Express Capability so that drivers didn't
need to be aware of differences between v1 and v2 of the PCI
Express Capability.

Replace pci_read_config_word() and pci_write_config_word() calls with
pcie_capability_read_word() and pcie_capability_write_word().

As pointed out by Firo Yang, a netdev tx timeout may trigger just before an
ethtool set_channels operation is started. be_tx_timeout(), which dumps
some queue structures, is not written to run concurrently with
be_update_queues(), which frees/allocates those queues structures. Add some
synchronization between the two.

This patch fixes an issue seen on Power systems with bnx2x which results
in the skb is NULL WARN_ON in bnx2x_free_tx_pkt firing due to the skb
pointer getting loaded in bnx2x_free_tx_pkt prior to the hw_cons
load in bnx2x_tx_int. Adding a read memory barrier resolves the issue.

The RX power read from the SFP uses units of 0.1uW. This must be
scaled to units of uW for HWMON. This requires a divide by 10, not the
current 100.

ieee80211_set_wmm_default() normally sets up the initial CW min/max for
each queue, except that it skips doing this if the driver doesn't
support ->conf_tx. We still end up calling drv_conf_tx() in some cases
(e.g., ieee80211_reconfig()), which also still won't do anything
useful...except it complains here about the invalid CW parameters.

Let's just skip the WARN if we weren't going to do anything useful with
the parameters.

flow_offload fixes

The following patchset contains fixes for the flow_offload infrastructure:

1) Fix possible build breakage before patch 3/4. Both the flow_offload
   infrastructure and OVS define the flow_stats structure. Patch 3/4 in
   this batch indirectly pulls in the flow_stats definition from
   include/net/flow_offload.h into OVS, leading to structure redefinition
   compile-time errors.

2) Remove netns parameter from flow_block_cb_alloc(), this is not
   required as Jiri suggests. The flow_block_cb_is_busy() function uses
   the per-driver block list to check for used blocks which was the
   original intention for this parameter.

3) Rename tc_setup_cb_t to flow_setup_cb_t. This callback is not
   exclusive of tc anymore, this might confuse the reader as Jiri
   suggests, fix this semantic inconsistency.

   Add #include <linux/list.h> to include/net/netfilter/nf_tables_offload.h
   to avoid a compile break with CONFIG_HEADER_TEST=y.

4) Fix block sharing feature: Add flow_block structure and use it,
   update flow_block_cb_lookup() to use this flow_block object.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

This object stores the flow block callbacks that are attached to this

There is a flow_stats structure defined in include/net/flow_offload.h
and a follow up patch adds #include <net/flow_offload.h> to
net/sch_generic.h.

This breaks compilation since OVS codebase includes net/sock.h which
pulls in linux/filter.h which includes net/sch_generic.h.

In file included from ./include/net/sch_generic.h:18:0,
                 from ./include/linux/filter.h:25,
                 from ./include/net/sock.h:59,
                 from ./include/linux/tcp.h:19,
                 from net/openvswitch/datapath.c:24

This definition takes precedence on OVS since it is placed in the
networking core, so rename flow_stats in OVS to sw_flow_stats since
this structure is contained in sw_flow.

 "Dave is back in shape, but now family got it so I'm doing the pull.
  Two things worthy of note:

   - nouveau feature pull was way too late, Dave&me decided to not take
     that, so Ben spun up a pull with just the fixes.

   - after some chatting with the arm display maintainers we decided to
     change a bit how that's maintained, for more oversight/review and
     cross vendor collab.

  More details below:

  nouveau:
   - bugfixes
   - TU116 enabling (minor iteration) :w

  amdgpu:
   - large pile of fixes for new hw support this release (navi, vega20)
   - audio hotplug fix
   - bunch of corner cases and small fixes all over for amdgpu/kfd

  komeda:
   - back out some new properties (from this merge window) that needs
     more pondering.

  bochs:
   - fb pitch setup

  core:
   - a new panel quirk
   - misc fixes"

Merge yet more updates from Andrew Morton:
 "The rest of MM and a kernel-wide procfs cleanup.

  Summary of the more significant patches:

   - Patch series "mm/memory_hotplug: Factor out memory block
     devicehandling", v3. David Hildenbrand.

     Some spring-cleaning of the memory hotplug code, notably in
     drivers/base/memory.c

   - "mm: thp: fix false negative of shmem vma's THP eligibility". Yang
     Shi.

     Fix /proc/pid/smaps output for THP pages used in shmem.

   - "resource: fix locking in find_next_iomem_res()" + 1. Nadav Amit.

     Bugfix and speedup for kernel/resource.c

   - Patch series "mm: Further memory block device cleanups", David
     Hildenbrand.

     More spring-cleaning of the memory hotplug code.

   - Patch series "mm: Sub-section memory hotplug support". Dan
     Williams.

     Generalise the memory hotplug code so that pmem can use it more
     completely. Then remove the hacks from the libnvdimm code which
     were there to work around the memory-hotplug code's constraints.

   - "proc/sysctl: add shared variables for range check", Matteo Croce.

     We have about 250 instances of

          int zero;
          ...
                  .extra1 = &zero,

     in the tree. This is a tree-wide sweep to make all those private
     "zero"s and "one"s use global variables.

     Alas, it isn't practical to make those two global integers const"

Commit c5c27a0a ("x86/stacktrace: Remove the pointless ULONG_MAX
marker") removes ULONG_MAX marker from user stack trace entries but
trace_user_stack_print() still uses the marker and it outputs unnecessary
"??".

For example:

            less-1911  [001] d..2    34.758944: <user stack trace>
   =>  <00007f16f2295910>
   => ??
   => ??
   => ??
   => ??
   => ??
   => ??
   => ??

The user stack trace code zeroes the storage before saving the stack, so if
the trace is shorter than the maximum number of entries it can terminate
the print loop if a zero entry is detected.

This can happen because the NF_TABLES_BRIDGE dependency itself is just a
'bool'.  Make the symbol a 'tristate' instead so Kconfig can propagate the
dependencies correctly.
