5694785cf0 drm/amdgpu: Fix undue fallthroughs in golden registers initialization
As I was staring at the si_init_golden_registers code, I noticed that
the Pitcairn initialization silently falls through the Cape Verde
initialization, and the Oland initialization falls through the Hainan
initialization. However there is no comment stating that this is
intentional, and the radeon driver doesn't have any such fallthrough,
so I suspect this is not supposed to happen.

ed254971ed tcp: avoid setting cwnd to invalid ssthresh after cwnd reduction states
If the sender switches the congestion control during ECN-triggered
cwnd-reduction state (CA_CWR), upon exiting recovery cwnd is set to
the ssthresh value calculated by the previous congestion control. If
the previous congestion control is BBR that always keep ssthresh
to TCP_INIFINITE_SSTHRESH, cwnd ends up being infinite. The safe
step is to avoid assigning invalid ssthresh value when recovery ends.

4d96f12a07 ibmvnic: Initialize SCRQ's during login renegotiation
SCRQ resources are freed during renegotiation, but they are not
re-allocated afterwards due to some changes in the initialization
process. Fix that by re-allocating the memory after renegotation.

SCRQ's can also be freed if a server capabilities request fails.
If this were encountered during a device reset for example,
SCRQ's may not be re-allocated. This operation is not necessary
anymore so remove it.

The cited commit introduced the following new enum value in file

aa6c16c43b net: bcmgenet: drop COMPILE_TEST dependency
The last patch added the dependency on 'OF && HAS_IOMEM' but left
COMPILE_TEST as an alternative, which kind of defeats the purpose
of adding the dependency, we still get randconfig build warnings:

warning: (NET_DSA_BCM_SF2 && BCMGENET) selects MDIO_BCM_UNIMAC which has unmet direct dependencies (NETDEVICES && MDIO_BUS && HAS_IOMEM && OF_MDIO)

For compile-testing purposes, we don't really need this anyway,
as CONFIG_OF can be enabled on all architectures, and HAS_IOMEM
is present on all architectures we do meaningful compile-testing on
(the exception being arch/um).

This makes both OF and HAS_IOMEM hard dependencies.

When USB plugged/unplugged at fast rate,
lan78xx_mdio_init() in lan78xx_bind() failing case is not handled.
Whenever  lan78xx_mdio_init() failed, dev->mdiobus will be freed, however
since lan78xx_bind() not consider as error and try to proceed for
further initialization in lan78xx_probe() which leads system hung/crash.
Also when register_netdev() failed, netdev is freed without calling lan78xx_unbind().

8466489ef5 xhci: Reset Renesas uPD72020x USB controller for 32-bit DMA issue
The Renesas uPD72020x XHCI controller seems to suffer from a really
annoying bug, where it may retain some of its DMA programming across a XHCI
reset, and despite the driver correctly programming new DMA addresses.
This is visible if the device has been using 64-bit DMA addresses, and is
then switched to using 32-bit DMA addresses.  The top 32 bits of the
address (now zero) are ignored are replaced by the 32 bits from the
*previous* programming.  Sticking with 64-bit DMA always works, but doesn't
seem very appropriate.

A PCI reset of the device restores the normal functionality, which is done
at probe time.  Unfortunately, this has to be done before any quirk has
been discovered, hence the intrusive nature of the fix.

39a06b67c2 irqchip/gic: Ensure we have an ISB between ack and ->handle_irq
Devices that expose their interrupt status registers via system
registers (e.g. Statistical profiling, CPU PMU, DynamIQ PMU, arch timer,
vgic (although unused by Linux), ...) rely on a context synchronising
operation on the CPU to ensure that the updated status register is
visible to the CPU when handling the interrupt. This usually happens as
a result of taking the IRQ exception in the first place, but there are
two race scenarios where this isn't the case.

For example, let's say we have two peripherals (X and Y), where Y uses a
system register for its interrupt status.

Case 1:
1. CPU takes an IRQ exception as a result of X raising an interrupt
2. Y then raises its interrupt line, but the update to its system
   register is not yet visible to the CPU
3. The GIC decides to expose Y's interrupt number first in the Ack
   register
4. The CPU runs the IRQ handler for Y, but the status register is stale

Case 2:
1. CPU takes an IRQ exception as a result of X raising an interrupt
2. CPU reads the interrupt number for X from the Ack register and runs
   its IRQ handler
3. Y raises its interrupt line and the Ack register is updated, but
   again, the update to its system register is not yet visible to the
   CPU.
4. Since the GIC drivers poll the Ack register, we read Y's interrupt
   number and run its handler without a context synchronisation
   operation, therefore seeing the stale register value.

In either case, we run the risk of missing an IRQ. This patch solves the
problem by ensuring that we execute an ISB in the GIC drivers prior
to invoking the interrupt handler. This is already the case for GICv3
and EOIMode 1 (the usual case for the host).

Merge tag 'asoc-fix-v4.13-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus

ASoC: Fixes for v4.13

Quite a few fixes here that have been sent since the merge window, the
biggest one is the fix from Tony for some confusion with the device
property API which was causing issues with the of-graph card.  This is
fixed with some changes in the graph API itself as it seemed very likely
to be error prone.

When blk_mq_get_request() failed, preempt counter isn't
released, and blk_mq_make_request() doesn't release the counter
too.

This patch fixes the issue, and makes sure that preempt counter
is only held if rq is allocated successfully. The same policy is
applied on .q_usage_counter too.

7e9e9202bc xfrm: Clear RX SKB secpath xfrm_offload
If an incoming packet undergoes XFRM crypto-offload, its secpath is
filled with xfrm_offload struct denoting offload information.

If the SKB is then forwarded to a device which supports crypto-
offload, the stack wrongfully attempts to offload it (even though
the output SA may not exist on the device) due to the leftover
secpath xo.

Clear the ingress xo by zeroizing secpath->olen just before
delivering the decapsulated packet to the network stack.

a9b28c2bf0 esp6: Fix RX checksum after header pull
Both ip6_input_finish (non-GRO) and esp6_gro_receive (GRO) strip
the IPv6 header without adjusting skb->csum accordingly. As a
result CHECKSUM_COMPLETE breaks and "hw csum failure" is written
to the kernel log by netdev_rx_csum_fault (dev.c).

Fix skb->csum by substracting the checksum value of the pulled IPv6
header using a call to skb_postpull_rcsum.

This affects both transport and tunnel modes.

Note that the fix occurs far from the place that the header was
pulled. This is based on existing code, see:
ipv6_srh_rcv() in exthdrs.c and rawv6_rcv() in raw.c

e9cba69448 xfrm6: Fix CHECKSUM_COMPLETE after IPv6 header push
xfrm6_transport_finish rebuilds the IPv6 header based on the
original one and pushes it back without fixing skb->csum.
Therefore, CHECKSUM_COMPLETE is no longer valid and the packet
gets dropped.

Fix skb->csum by calling skb_postpush_rcsum.

the change is not needed in the sibling xfrm4_transport_finish
function.

f7f8c1756e nand: fix wrong default oob layout for small pages using soft ecc
When using soft ecc, if no ooblayout is given, the core automatically
uses one of the nand_ooblayout_{sp,lp}*() functions to determine the
layout inside the out of band data.

Until kernel version 4.6, struct nand_ecclayout was used for that
purpose. During the migration from 4.6 to 4.7, an error shown up in the
small page layout, in the case oob section is only 8 bytes long.

The layout was using three bytes (0, 1, 2) for ecc, two bytes (3, 4)
as free bytes, one byte (5) for bad block marker and finally
two bytes (6, 7) as free bytes, as shown there:

[linux-4.6] drivers/mtd/nand/nand_base.c:52
static struct nand_ecclayout nand_oob_8 = {
	.eccbytes = 3,
	.eccpos = {0, 1, 2},
	.oobfree = {
		{.offset = 3,
		 .length = 2},
		{.offset = 6,
		 .length = 2} }
};

This fixes the current implementation which is incoherent. It
references bit 3 at the same time as an ecc byte and a free byte.

Furthermore, it is clear with the previous implementation that there
is only one ecc section with 8 bytes oob sections. We shall return
-ERANGE in the nand_ooblayout_ecc_sp() function when asked for the
second section.

cb5b136c00 Merge branch 'dsa-rework-EEE-support'
Vivien Didelot says:

====================
net: dsa: rework EEE support

EEE implies configuring the port's PHY and MAC of both ends of the wire.

The current EEE support in DSA mixes PHY and MAC configuration, which is
bad because PHYs must be configured through a proper PHY driver. The DSA
switch operations for EEE are only meant for configuring the port's MAC,
which are integrated in the Ethernet switch device.

This patchset fixes the EEE support in qca8k driver, makes the DSA layer
call phy_init_eee for all drivers, and remove the EEE support from the
mv88e6xxx driver since the Marvell PHY driver should be enough for it.

Changes in v2:
 - make PHY device and DSA EEE ops mandatory for slave EEE operations.
 - simply return 0 in drivers which don't need to do anything to
   configure the port' MAC. Subsequent PHY calls will be enough.
