If CONFIG_DEBUG_SLAB=y, and no PCIe card is inserted, the kernel crashes
during probe on r8a7791/koelsch:
rcar-pcie fe000000.pcie: PCIe link down
Unable to handle kernel paging request at virtual address 6b6b6b6b
(seeing this message requires earlycon and keep_bootcon).
Indeed, pci_free_host_bridge() frees the PCI host bridge, including the
embedded rcar_pcie object, so pci_free_resource_list() must not be called
afterwards.
To fix this, move the call to pci_free_resource_list() up, and update the
label name accordingly.

usb: fixes for v4.15-rc4
We have a few fixes on dwc3:
- one fix which only happens with some implementations where we need to
wait longer for some commands to finish.
- Another fix for high-bandwidth isochronous endpoint programming making
sure that we send the correct DATA tokens in the correct sequence
- A couple PM fixes on dwc3-of-simple
The other synopsys controller driver (dwc2) got a fix for FIFO size
programming.
Other than these, we have a couple Kconfig fixes making sure that
dependencies are properly setup.

This reverts commit 7a9618a22aadffb55027d665491adf466bced61a.
Romain Izard recently reported that commit 7a9618a22aad ended up
allowing every legacy gadget driver to statically linked to the
kernel, however that doesn't work, since only one legacy gadget can be
bound to a controller. Because of that, let's revert the original commit
and fix the problem.

Configuring the USB_G_WEBCAM driver as built-in leads to a link
error when CONFIG_VIDEO_V4L2 is a loadable module:
drivers/usb/gadget/function/f_uvc.o: In function `uvc_function_setup':
f_uvc.c:(.text+0xfe): undefined reference to `v4l2_event_queue'
drivers/usb/gadget/function/f_uvc.o: In function `uvc_function_ep0_complete':
f_uvc.c:(.text+0x188): undefined reference to `v4l2_event_queue'
This changes the Kconfig dependency to disallow that configuration,
and force it to be a module in that case as well.
This is apparently a rather old bug, but very hard to trigger
even in thousands of randconfig builds.

Guenter Roeck reported an interrupt storm on a prototype system which is
based on Cyan Chromebook. The root cause turned out to be a incorrectly
configured pin that triggers spurious interrupts. This will be fixed in
coreboot but currently we need to prevent the interrupt storm from
happening by masking all interrupts (but not GPEs) on those systems.

Avoid that scsi_show_rq() triggers a NULL pointer dereference if called
after sd_uninit_command(). Swap the NULL pointer assignment and the
mempool_free() call in sd_uninit_command() to make it less likely that
scsi_show_rq() triggers a use-after-free. Note: even with these changes
scsi_show_rq() can trigger a use-after-free but that's a lesser evil
than e.g. suppressing debug information for T10 PI Type 2 commands
completely. This patch fixes the following oops:

The return value of smp_execute_task_sg() is the untransferred residual,
but bsg_job_done() requires the length of payload received. This makes
SMP passthrough commands from userland by sg ioctl to libsas get a wrong
response. The userland tools such as smp_utils failed because of these
wrong responses:
~#smp_discover /dev/bsg/expander-2\:13
response too short, len=0
~#smp_discover /dev/bsg/expander-2\:134
response too short, len=0
Fix this by passing the actual received length to bsg_job_done(). And if
smp_execute_task_sg() returns 0, this means received length is exactly
the buffer length.

Sending the switch state change twice within the same frame is invalid
evdev protocol and only works if the client handles keys immediately as
well. Processing events immediately is incorrect, it forces a fake
order of events that does not exist on the device.
Recent versions of libinput changed to only process the device state and
SYN_REPORT time, so now the key event is lost.

Only insert our special drain CQEs to support ib_drain_sq/rq() after
the wq is flushed. Otherwise, existing but not yet polled CQEs can be
returned out of order to the user application. This can happen when the
QP has exited RTS but not yet flushed the QP, which can happen during
a normal close (vs abortive close).
In addition never count the drain CQEs when determining how many CQEs
need to be synthesized during the flush operation. This latter issue
should never happen if the QP is properly flushed before inserting the
drain CQE, but I wanted to avoid corrupting the CQ state. So we handle
it and log a warning once.

Not all variants of the sh_eth hardware have Gigabit
support. Unfortunately, the current driver doesn't tell the PHY about
the limited MAC capabilities. Due to this, if you have a Gigabit
capable PHY, the PHY will advertise its Gigabit capability and
establish a link at 1Gbit/s, even though the MAC doesn't support it.
In order to avoid this, we use the recently introduced
phy_set_max_speed() to tell the PHY to not advertise speed higher than
100 MBit/s.
Tested on a SH7786 platform, with a Gigabit PHY.

The purpose of this change is to fix the incorrect detection of the link
partner (LP) advertised capabilities which sometimes happens with this PHY
(roughly 1 time in a dozen)
This issue may cause the link to be negotiated at 10Mbps/Full or
10Mbps/Half when 100MBps/Full is actually possible. In some case, the link
is even completely broken and no communication is possible.
To detect the corruption, we must look for a magic undocumented bit in the
WOL bank (hint given by the SoC vendor kernel) but this is not enough to
cover all cases. We also have to look at the LPA ack. If the LP supports
Aneg but did not ack our base code when aneg is completed, we assume
something went wrong.
The detection of a corrupted LPA triggers a restart of the aneg process.
This solves the problem but may take up to 6 retries to complete.

Middle-layer code doing suspend-time optimizations for devices with
the DPM_FLAG_SMART_SUSPEND flag set (currently, the PCI bus type and
the ACPI PM domain) needs to make the core skip ->thaw_early and
->thaw callbacks for those devices in some cases and it sets the
power.direct_complete flag for them for this purpose.
However, it turns out that setting power.direct_complete outside of
the PM core is a bad idea as it triggers an excess invocation of
pm_runtime_enable() in device_resume().
For this reason, provide a helper to clear power.is_late_suspended
and power.is_suspended to be invoked by the middle-layer code in
question instead of setting power.direct_complete and make that code
call the new helper.

Commit adfa543e7314 ("dmatest: don't use set_freezable_with_signal()")
introduced a bug (that is in fact documented by the patch commit text)
that leaves behind a dangling pointer. Since the done_wait structure is
allocated on the stack, future invocations to the DMATEST can produce
undesirable results (e.g., corrupted spinlocks).
Commit a9df21e34b42 ("dmaengine: dmatest: warn user when dma test times
out") attempted to WARN the user that the stack was likely corrupted but
did not fix the actual issue.
This patch fixes the issue by pushing the wait queue and callback
structs into the the thread structure. If a failure occurs due to time,
dmaengine_terminate_all will force the callback to safely call
wake_up_all() without possibility of using a freed pointer.

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC fixes from Olof Johansson:
- A revert of all SCPI changes from the 4.15 merge window. They had
regressions on the Amlogic platforms, and the submaintainer isn't
around to fix these bugs due to vacation, etc. So we agreed to revert
and revisit in next release cycle.
- A series fixing a number of bugs for ARM CCN interconnect, around
module unload, smp_processor_id() in preemptable context, and fixing
some memory allocation failure checks.
- A handful of devicetree fixes for different platforms, fixing
warnings and errors that were previously ignored by the compiler.
- The usual set of mostly minor fixes for different platforms.

The bytes_compl and pkts_compl pointers passed to efx_dequeue_buffers
cannot be NULL. Add a paranoid warning to check this condition and fix
the one case where they were NULL.
efx_enqueue_unwind() is called very rarely, during error handling.
Without this fix it would fail with a NULL pointer dereference in
efx_dequeue_buffer, with efx_enqueue_skb in the call stack.

This controller does not support EEE, but it may connect to a PHY
which supports EEE and advertises EEE by default, while its link
partner also advertises EEE. If this happens, the PHY enters low
power mode when the traffic rate is low and causes packet loss.
This patch disables EEE advertisement by default for any PHY that
gianfar connects to, to prevent the above unwanted outcome.
