0bbd7dad34 tun: make tun_build_skb() thread safe
tun_build_skb() is not thread safe since it uses per queue page frag,
this will break things when multiple threads are sending through same
queue. Switch to use per-thread generator (no lock involved).

Fixes: 66ccbc9c87 ("tap: use build_skb() for small packet")

120e9dabaf dccp: defer ccid_hc_tx_delete() at dismantle time
syszkaller team reported another problem in DCCP [1]

Problem here is that the structure holding RTO timer
(ccid2_hc_tx_rto_expire() handler) is freed too soon.

We can not use del_timer_sync() to cancel the timer
since this timer wants to grab socket lock (that would risk a dead lock)

Solution is to defer the freeing of memory when all references to
the socket were released. Socket timers do own a reference, so this
should fix the issue.

494bea39f3 openvswitch: fix skb_panic due to the incorrect actions attrlen
For sw_flow_actions, the actions_len only represents the kernel part's
size, and when we dump the actions to the userspace, we will do the
convertions, so it's true size may become bigger than the actions_len.

But unfortunately, for OVS_PACKET_ATTR_ACTIONS, we use the actions_len
to alloc the skbuff, so the user_skb's size may become insufficient and
oops will happen like this:
  skbuff: skb_over_panic: text:ffffffff8148fabf len:1749 put:157 head:
  ffff881300f39000 data:ffff881300f39000 tail:0x6d5 end:0x6c0 dev:<NULL>

   [<ffffffffa029848b>] ovs_vport_receive+0xa1/0xc3 [openvswitch]
  [...]

Also we can find that the actions_len is much little than the orig_len:
  crash> struct sw_flow_actions 0xffff8812f539d000
  struct sw_flow_actions {
    rcu = {
      next = 0xffff8812f5398800,
      func = 0xffffe3b00035db32
    },
    orig_len = 1384,
    actions_len = 592,
    actions = 0xffff8812f539d01c
  }

So as a quick fix, use the orig_len instead of the actions_len to alloc
the user_skb.

Last, this oops happened on our system running a relative old kernel, but
the same risk still exists on the mainline, since we use the wrong
actions_len from the beginning.

e543002f77 qdisc: add tracepoint qdisc:qdisc_dequeue for dequeued SKBs
The main purpose of this tracepoint is to monitor bulk dequeue
in the network qdisc layer, as it cannot be deducted from the
existing qdisc stats.

The txq_state can be used for determining the reason for zero packet
dequeues, see enum netdev_queue_state_t.

Notice all packets doesn't necessary activate this tracepoint. As
qdiscs with flag TCQ_F_CAN_BYPASS, can directly invoke
sch_direct_xmit() when qdisc_qlen is zero.

Remember that perf record supports filters like:

 perf record -e qdisc:qdisc_dequeue \
  --filter 'ifindex == 4 && (packets > 1 || txq_state > 0)'

fc244e3af2 Removal of the deprectated num-slots property from all Rockchip dw-mmc
nodes. The rv1108 gains support for sd-cards on the evaluation board and
 the general nodes get a bit of cosmetic. On rk3288 the evb gains support
 saradc and the adc-key connected to it while some more boards also get
 their mali gpu enabled (fennec, evb, tinker).
 
 The biggest set of changes can be found on the rk3228/rk3229 combo this
 time. It gets core support for efuse, sdmmc, sdio, io-domans and spdif
 as well as a separate rk3229.dtsi that will keep the slight differences
 between the two brothers rk3228/rk3229. The evaluation board also gets
 some attention and abled nodes (regulators, io-domains, emmc, tsadc keys)
 
 But I think the most interesting change is the cpu enable-method for it.
 Instead of using the older in-kernel method, we're now also moving to
 handling this in firmware via the psci interface on 32bit Rockchip socs.
 In a recently merged pull request [0] support for the rk3228/rk3229 was
 added to OP-TEE including the psci support and it seems supporting other
 32bit Rockchip socs that way is also planned for the future.

Merge tag 'v4.14-rockchip-dts32-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip into next/dt

Pull "Rockchip dts32 changes for 4.14" from Heiko Stübner:

Removal of the deprectated num-slots property from all Rockchip dw-mmc
nodes. The rv1108 gains support for sd-cards on the evaluation board and
the general nodes get a bit of cosmetic. On rk3288 the evb gains support
saradc and the adc-key connected to it while some more boards also get
their mali gpu enabled (fennec, evb, tinker).

The biggest set of changes can be found on the rk3228/rk3229 combo this
time. It gets core support for efuse, sdmmc, sdio, io-domans and spdif
as well as a separate rk3229.dtsi that will keep the slight differences
between the two brothers rk3228/rk3229. The evaluation board also gets
some attention and abled nodes (regulators, io-domains, emmc, tsadc keys)

But I think the most interesting change is the cpu enable-method for it.
Instead of using the older in-kernel method, we're now also moving to
handling this in firmware via the psci interface on 32bit Rockchip socs.

f7ec9146eb Renesas ARM Based SoC DT Updates for v4.14
Changes of note:
 
 * Add pin controller support to the RZ/G1M (r8a7743) SoC and
   RZ/A1 (r7s72100) SoCs now that the driver is available in v4.13-rc1.
 
 * Add GPIO support to the RZ/G1M (r8a7743) SoC now that the driver
   is availabe in v4.13-rc1.
 
 * Enable MMCIF0 and Ethernet AVB support on the RZ/G1M (r8a7743) SoC and
   the iWave-RZG1M-20M Qseven SOM. This depends on newly added pin
   controller support noted above.
 
 * Use R-Car Gen 2 fallback binding for vin nodes
 
   This makes binding use consistent across R-Car Gen 2 SoCs.
   It does not have any run-time effect
 
 * Use SMP jump stub SRAM region from DT on R-Car Gen 2 SoCs
 
   Geert Uytterhoeven says, "The R-Car Gen2 platform code for CPU core
   bringup needs to copy a jump stub to on-SoC SRAM.  Currently it uses a
   hardcoded address pointing to ICRAM1."
 
 * Add Inter Connect RAM to R-Car Gen 2 and RZ/G1 SoCs
 
   Geert Uytterhoeven says, "R-Car Gen2 and RZ/G1 SoCs contain two or three
   blocks of SRAM, which can be used for several purposes.  One such purpose
   is holding a jump stub for CPU core bringup."
 * Use generic compatible string for I2C EEPROM for RZ/A1 (r7s72100) SoC
   and koelsch board.
 
   This is part of a tree-wide cleanup by Javier Martinez Canillas

- We have a reset controller
- We have a clock controller
- We need ARM_AMBA for FTDMAC020 which is PL08x
- We need to select the pin controller (being merged

ac237cd16f Updates to for omap debug_ll code to use generic DEBUG_UART_8250 code.
The legacy code to try to detect the debug_ll uart based on machine

 options stay the same, we just need to define the port configuration
 now.

6a1aa09b15 Renesas ARM Based SoC Updates for v4.14
* Add debug-ll support to RZ/G1M (r8a7743) SoC
 
   Chris Paterson says, "RZ/G1M uses SCIF0 for the debug console, like most
   of the R-Car Gen2 SoCs."
 
 * Remove ARCH_SHMOBILE_MULTI
 
   Geert Uytterhoeven says, "The migration from ARCH_SHMOBILE_MULTI to
   ARCH_RENESAS has been completed in v4.12..."
 
 * Correct arch timer frequency on RZ/G1M (r8a7743) SoC
 
   Geert Uytterhoeven says, "According to the datasheet, the frequency of
   the ARM architecture timer on RZ/G1E depends on the frequency of the ZS
   clock..."
 
 * Add support for CPG/MSSR bindings
 
   Geert Uytterhoeven says, "When using the new CPG/MSSR bindings, there is
   no longer a "renesas,rcar-gen2-cpg-clocks" node, and the code to obtain
   the external clock crystal frequency falls back to a default of 20 MHz.
   While this is correct for all upstream R-Car Gen2 and RZ/G1 boards, this
   is not necessarily the case for out-of-tree third party boards.
 
   Add support for finding the external clock crystal oscillator on RZ/G1M,
   and on R-Car H2, M2-W, and M2-N using the new CPG/MSSR bindings, through
   the corresponding "renesas,r8a77xx-cpg-mssr" nodes."
 
 * Obtain jump stub region from DT
 
   Geert Uytterhoeven says, "Add support for obtaining from DT the SRAM
   region to store the jump stub for CPU core bringup, according to the
   renesas,smp-sram DT bindings."

db86ab0616 soc: versatile: remove unnecessary static in realview_soc_probe()
Remove unnecessary static on local variables syscon_regmap.
Such variables are initialized before being used, on every
execution path throughout the functions. The static has no
benefit and, removing it reduces the object file size.

This issue was detected using Coccinelle and the following
semantic patch:

@bad exists@
position p;
identifier x;
type T;
@@

static T x@p;
...
x = <+...x...+>

@@
identifier x;
expression e;
type T;
position p != bad.p;
@@

-static
 T x@p;
 ... when != x
     when strict
?x = e;

In the following log you can see the difference in the object file size.
This log is the output of the size command, before and after the code
change:

we ensure the value size is 4bytes earlier in the function because all
values should be netdev ifindex values.

The second check is harmless but is not needed so remove it.

    norandmaps  Don't use address space randomization. Equivalent
                to echo 0 > /proc/sys/kernel/randomize_va_space

but it doesn't work because arch_rnd() which is used to randomize
mm->mmap_base returns a random value unconditionally. And as Kirill
pointed out, ADDR_NO_RANDOMIZE is broken by the same reason.

Just shift the PF_RANDOMIZE check from arch_mmap_rnd() to arch_rnd().
