Three changes for the Armada DRM driver:
1. Add back the flags which tell the DRM core that we can do vblank. This
was removed in error during the recent restructuring, and came to light
while trying textured Xv rendering.
2. Fixing a refcount leak with Xv overlay.
3. As per recent discussion, the drm_vblank_pre_modeset() calls can cause
deadlock with other changes to generic code. This change prevents those
deadlocks by switching to the drm_crtc_vblank_*() calls instead.
* 'drm-armada-fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm:
drm/armada: convert to use vblank_on/off calls
drm/armada: fix page_flip refcounting leak
drm/armada: add IRQ support back
introduce two configs:
- hidden CONFIG_BPF to select eBPF interpreter that classic socket filters
depend on
- visible CONFIG_BPF_SYSCALL (default off) that tracing and sockets can use
that solves several problems:
- tracing and others that wish to use eBPF don't need to depend on NET.
They can use BPF_SYSCALL to allow loading from userspace or select BPF
to use it directly from kernel in NET-less configs.
- in 3.18 programs cannot be attached to events yet, so don't force it on
- when the rest of eBPF infra is there in 3.19+, it's still useful to
switch it off to minimize kernel size

cxgb4 : DCBx fixes for apps/host lldp agents
This patchset contains some minor fixes for cxgb4 DCBx code. Chiefly, cxgb4
was not cleaning up any apps added to kernel app table when link was lost.
Disabling DCBx in firmware would automatically set DCBx state to host-managed
and enabled, we now wait for an explicit enable call from an lldp agent instead
First patch was originally sent to net-next, but considering it applies to
correcting behaviour of code already in net, I think it qualifies as a bug fix.

Netfilter fixes for net
The following patchset contains Netfilter fixes for your net tree,
they are:
1) Allow to recycle a TCP port in conntrack when the change role from
server to client, from Marcelo Leitner.
2) Fix possible off by one access in ip_set_nfnl_get_byindex(), patch
from Dan Carpenter.
3) alloc_percpu returns NULL on error, no need for IS_ERR() in nf_tables
chain statistic updates. From Sabrina Dubroca.
4) Don't compile ip options in bridge netfilter, this mangles the packet
and bridge should not alter layer >= 3 headers when forwarding packets.
Patch from Herbert Xu and tested by Florian Westphal.
5) Account the final NLMSG_DONE message when calculating the size of the
nflog netlink batches. Patch from Florian Westphal.
6) Fix a possible netlink attribute length overflow with large packets.
Again from Florian Westphal.
7) Release the skbuff if nfnetlink_log fails to put the final
NLMSG_DONE message. This fixes a leak on error. This shouldn't ever
happen though, otherwise this means we miscalculate the netlink batch
size, so spot a warning if this ever happens so we can track down the
problem. This patch from Houcheng Lin.
8) Look at the right list when recycling targets in the nft_compat,
patch from Arturo Borrero.

Commit 34e5a5273d ("cpufreq: cpufreq-dt: extend with
platform_data") changed cpufreq_init() to only call
cpumask_setall(policy->cpus) if the platform data indicates that all
CPUs share the same clock. Before, cpufreq_generic_init() did this
unconditionally.
This causes a crash on r8a7791/koelsch when resuming from s2ram:

If we couldn't find our extent item, we accessed the current slot
(path->slots[0]) to check if it corresponds to an equivalent skinny
metadata item. However this slot could be beyond our last item in the
leaf (i.e. path->slots[0] >= btrfs_header_nritems(leaf)), in which case
we shouldn't process it.
Since btrfs_lookup_extent() is only used to find extent items for data
extents, fix this by removing completely the logic that looks up for an
equivalent skinny metadata item, since it can not exist.

If a device's dev_pm_ops::freeze callback fails during the QUIESCE

If an asynchronous suspend_late or freeze_late callback fails
during the SUSPEND, FREEZE or QUIESCE phases, we don't propagate the
corresponding error correctly, in effect ignoring the error and
continuing the suspend-to-ram/hibernation. During suspend-to-ram this
could leave some devices without a valid saved context, leading to a
failure to reinitialize them during resume. During hibernation this
could leave some devices active interfeering with the creation /
restoration of the hibernation image. Also this could leave the
corresponding devices without a valid saved context and failure to
reinitialize them during resume.

Commit 6ab3430129 ("mfd: Add ACPI support") made the MFD subdevices
share the parent MFD ACPI companion if no _HID/_CID is specified for
the subdevice in mfd_cell description. However, since all the subdevices
share the ACPI companion, the match and modalias generation logic started
to use the ACPI companion as well resulting this:
# cat /sys/bus/platform/devices/HID-SENSOR-200041.6.auto/modalias
acpi:INT33D1:PNP0C50:
instead of the expected one
# cat /sys/bus/platform/devices/HID-SENSOR-200041.6.auto/modalias
platform:HID-SENSOR-200041
In other words the subdevice modalias is overwritten by the one taken from
ACPI companion. This causes udev not to load the driver anymore.
It is useful to be able to share the ACPI companion so that MFD subdevices
(and possibly other devices as well) can access the ACPI resources even if
they do not have ACPI representation in the namespace themselves.
An example where this is used is Minnowboard LPC driver that creates GPIO
as a subdevice among other things. Without the ACPI companion gpiolib is
not able to lookup the corresponding GPIO controller from ACPI GpioIo
resource.
To fix this, restrict the match and modalias logic to be limited to the
first (primary) physical device associated with the given ACPI comapnion.
The secondary devices will still be able to access the ACPI companion,
but they will be matched in a different way.

The kernel provided vdso functions do not get a stack frame from the
calling function and therefore may not change the stack contents, unless
they allocate space on their own.
This problem was exposed with 070b7be633 "s390/vdso: replace stck with
stcke" which writes 16 bytes instead of 8 bytes into the stack frame. These
additional 8 bytes however were indeed used by the caller (glibc) to save
data and therefore this data was corrupted by the vdso code.

Commit 95b0e655f9 ("ARM: mm: don't limit default CMA region only to
low memory") extended CMA memory reservation to allow usage of high
memory. It relied on commit f7426b983a ("mm: cma: adjust address limit
to avoid hitting low/high memory boundary") to ensure that the reserved
block never crossed the low/high memory boundary. While the
implementation correctly lowered the limit, it failed to consider the
case where the base..limit range crossed the low/high memory boundary
with enough space on each side to reserve the requested size on either
low or high memory.
Rework the base and limit adjustment to fix the problem. The function
now starts by rejecting the reservation altogether for fixed
reservations that cross the boundary, tries to reserve from high memory
first and then falls back to low memory.

The fixed parameter to cma_declare_contiguous() tells the function
whether the given base address must be honoured or should be considered
as a hint only. The API considers a zero base address as meaning any
base address, which must never be considered as a fixed value.
Part of the implementation correctly checks both fixed and base != 0,
but two locations check the fixed value only. Set fixed to false when
base is 0 to fix that and simplify the code.

If activation of the CMA area fails its mutex won't be initialized,
leading to an oops at allocation time when trying to lock the mutex. Fix
this by setting the cma area count field to 0 when activation fails,
leading to allocation returning NULL immediately.

Turning vdd on/off can generate a long hpd pulse on eDP ports. In order
to handle hpd we would need to turn on vdd to perform aux transfers.
This would lead to an endless cycle of
"vdd off -> long hpd -> vdd on -> detect -> vdd off -> ..."
So ignore long hpd pulses on eDP ports. eDP panels should be physically
tied to the machine anyway so they should not actually disappear and
thus don't need long hpd handling. Short hpds are still needed for link
re-train and whatnot so we can't just turn off the hpd interrupt
entirely for eDP ports. Perhaps we could turn it off whenever the panel
is disabled, but just ignoring the long hpd seems sufficient.

Sometimes we seem to get utter garbage from DPCD reads. The resulting
buffer is filled with the same byte, and the operation completed without
errors. My HP ZR24w monitor seems particularly susceptible to this
problem once it's gone into a sleep mode.
The issue seems to happen only for the first AUX message that wakes the
sink up. But as the first AUX read we often do is the DPCD receiver
cap it does wreak a bit of havoc with subsequent link training etc. when
the receiver cap bw/lane/etc. information is garbage.
A sufficient workaround seems to be to perform a single byte dummy read
before reading the actual data. I suppose that just wakes up the sink
sufficiently and we can just throw away the returned data in case it's
crap. DP_DPCD_REV seems like a sufficiently safe location to read here.

Terratec PHASE 88 rack fw has two registers for source of clock, one is
for internal/external, and another is for wordclock/spdif for external.
When clock source is internal, information in another register has no meaning.
Thus it must be ignored, but current implementation decodes it. This causes
over-indexing reference to labels.
