Linus Torvalds 3ddc76dfc7 Merge branch 'timers-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull timer type cleanups from Thomas Gleixner:
 "This series does a tree wide cleanup of types related to
  timers/timekeeping.

   - Get rid of cycles_t and use a plain u64. The type is not really
     helpful and caused more confusion than clarity

   - Get rid of the ktime union. The union has become useless as we use
     the scalar nanoseconds storage unconditionally now. The 32bit
     timespec alike storage got removed due to the Y2038 limitations
     some time ago.

     That leaves the odd union access around for no reason. Clean it up.

  Both changes have been done with coccinelle and a small amount of
  manual mopping up"

Linus Torvalds b272f732f8 Merge branch 'smp-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull SMP hotplug notifier removal from Thomas Gleixner:
 "This is the final cleanup of the hotplug notifier infrastructure. The
  series has been reintgrated in the last two days because there came a
  new driver using the old infrastructure via the SCSI tree.

  Summary:

   - convert the last leftover drivers utilizing notifiers

   - fixup for a completely broken hotplug user

   - prevent setup of already used states

   - removal of the notifiers

   - treewide cleanup of hotplug state names

   - consolidation of state space

  There is a sphinx based documentation pending, but that needs review
  from the documentation folks"

Thomas Gleixner 8b0e195314 ktime: Cleanup ktime_set() usage
ktime_set(S,N) was required for the timespec storage type and is still
useful for situations where a Seconds and Nanoseconds part of a time value
needs to be converted. For anything where the Seconds argument is 0, this
is pointless and can be replaced with a simple assignment.

Thomas Gleixner 73c1b41e63 cpu/hotplug: Cleanup state names
When the state names got added a script was used to add the extra argument
to the calls. The script basically converted the state constant to a
string, but the cleanup to convert these strings into meaningful ones did
not happen.

Replace all the useless strings with 'subsys/xxx/yyy:state' strings which
are used in all the other places already.

Jason Wang bb91accf27 virtio-net: XDP support for small buffers
Commit f600b69050 ("virtio_net: Add XDP support") leaves the case of
small receive buffer untouched. This will confuse the user who want to
set XDP but use small buffers. Other than forbid XDP in small buffer
mode, let's make it work. XDP then can only work at skb->data since
virtio-net create skbs during refill, this is sub optimal which could
be optimized in the future.

Make the destruction of a nexthop group symmetric with its creation by

Thomas Petazzoni 8354491c9d net: mvpp2: fix dma unmapping of TX buffers for fragments
Since commit 71ce391dfb ("net: mvpp2: enable proper per-CPU TX
buffers unmapping"), we are not correctly DMA unmapping TX buffers for
fragments.

Indeed, the mvpp2_txq_inc_put() function only stores in the
txq_cpu->tx_buffs[] array the physical address of the buffer to be
DMA-unmapped when skb != NULL. In addition, when DMA-unmapping, we use
skb_headlen(skb) to get the size to be unmapped. Both of this works fine
for TX descriptors that are associated directly to a SKB, but not the
ones that are used for fragments, with a NULL pointer as skb:

 - We have a NULL physical address when calling DMA unmap
 - skb_headlen(skb) crashes because skb is NULL

This causes random crashes when fragments are used.

To solve this problem, we need to:

 - Store the physical address of the buffer to be unmapped
   unconditionally, regardless of whether it is tied to a SKB or not.

 - Store the length of the buffer to be unmapped, which requires a new
   field.

Instead of adding a third array to store the length of the buffer to be
unmapped, and as suggested by David Miller, this commit refactors the
tx_buffs[] and tx_skb[] arrays of 'struct mvpp2_txq_pcpu' into a
separate structure 'mvpp2_txq_pcpu_buf', to which a 'size' field is
added. Therefore, instead of having three arrays to allocate/free, we
have a single one, which also improve data locality, reducing the
impact on the CPU cache.

Heiko Stübner f217bfde24 net: ethernet: stmmac: dwmac-rk: make clk enablement first in powerup
Right now the dwmac-rk tries to set up the GRF-specific speed and link
options before enabling clocks, phys etc and on previous socs this works
because the GRF is supplied on the whole by one clock.

On the rk3399 however the GRF (General Register Files) clock-supply
has been split into multiple clocks and while there is no specific
grf-gmac clock like for other sub-blocks, it seems the mac-specific
portions are actually supplied by the general mac clock.

This results in hangs on rk3399 boards if the driver is build as module.
When built in te problem of course doesn't surface, as the clocks
are of course still on at the stage before clock_disable_unused.

To solve this, simply move the clock enablement to the first position
in the powerup callback. This is also a good idea in general to
enable clocks before everything else.

Tested on rk3288, rk3368 and rk3399 the dwmac still works on all of them.

Larry Finger 22b68b93ae rtlwifi: Fix kernel oops introduced with commit e496561473
With commit e496561473 {"rtlwifi: Use dev_kfree_skb_irq instead of
kfree_skb"), the method used to free an skb was changed because the
kfree_skb() was inside a spinlock. What was forgotten is that kfree_skb()
guards against a NULL value for the argument. Routine dev_kfree_skb_irq()
does not, and a test is needed to prevent kernel panics.

Tobias Klausmann d1f1c0e289 ath9k: do not return early to fix rcu unlocking
Starting with commit d94a461d7a ("ath9k: use ieee80211_tx_status_noskb
where possible") the driver uses rcu_read_lock() && rcu_read_unlock(), yet on
returning early in ath_tx_edma_tasklet() the unlock is missing leading to stalls
and suspicious RCU usage:

Since commit

  5a6681e22c ("sfc: separate out SFC4000 ("Falcon") support into new sfc-falcon driver")

there are two drivers for Solarflare devices, but both still show up
directly beneath "Ethernet driver support" in the Kconfig. Follow the
pattern of other vendors and group them beneath an own vendor Kconfig
entry for Solarflare.

jbrunet 57f3986231 net: phy: use boolean dt properties for eee broken modes
The patches regarding eee-broken-modes was merged before all people
involved could find an agreement on the best way to move forward.

While we agreed on having a DT property to mark particular modes as broken,
the value used for eee-broken-modes mapped the phy register in very direct
way. Because of this, the concern is that it could be used to implement
configuration policies instead of describing a broken HW.

In the end, having a boolean property for each mode seems to be preferred
over one bit field value mapping the register (too) directly.

of_irq_to_resource() is defined when CONFIG_OF_IRQ is defined. And also

Ido Schimmel 9a60c90722 mlxsw: spectrum: Mark split ports as such
When a port is split we should mark it as such, as otherwise the split
ports aren't renamed correctly (e.g. sw1p3 -> sw1p3s1) and the unsplit
operation fails:

$ devlink port split sw1p3 count 4
$ devlink port unsplit eth0
devlink answers: Invalid argument
[  598.565307] mlxsw_spectrum 0000:03:00.0 eth0: Port wasn't split

Arnd Bergmann 7729bad4fd qed: fix old-style function definition
The newly added file causes a harmless warning, with "make W=1":

drivers/net/ethernet/qlogic/qed/qed_iscsi.c: In function 'qed_get_iscsi_ops':
drivers/net/ethernet/qlogic/qed/qed_iscsi.c:1268:29: warning: old-style function definition [-Wold-style-definition]

This makes it a proper prototype.

Manuel Bessler c762eaa777 r6040: move spinlock in r6040_close as SOFTIRQ-unsafe lock order detected
'ifconfig eth0 down' makes r6040_close() trigger:
 INFO: HARDIRQ-safe -> HARDIRQ-unsafe lock order detected

Fixed by moving calls to phy_stop(), napi_disable(), netif_stop_queue()
to outside of the module's private spin_lock_irq block.

Found on a Versalogic Tomcat SBC with a Vortex86 SoC
