SDVO was the last connector that's still using the legacy paths
for properties, and this is with a reason!
This connector implements a lot of properties dynamically,
and some of them shared with the digital connector state,
so sdvo_connector_state subclasses intel_digital_connector_state.
set_property had a lot of validation, but this is handled in the
drm core, so most of the validation can die off. The properties
are written right before enabling the connector, since there is no
good way to update the properties without crtc.

Do the same as other connectors, attempt to detect hdmi audio in
the detect() callback, and only use the force_audio property as
override. Compute has_audio in pipe_config, and use that value
instead of the probed value directly.

intel_hdmi supports 3 properties, force_audio, broadcast rgb and
scaling mode. The last one is only created for eDP, so the is_eDP
in set_property is not required.
panel fitting and broadcast rgb are straightforward and only requires
changing compute_config.
force_audio is also used to force DVI mode, which means changes to
compute_config and mode_valid. mode_valid is called with
connection_mutex held, so it can safely dereference connector->state.

Some atomic properties are common between the various kinds of
connectors, for example a lot of them use panel fitting mode.
It makes sense to put a lot of it in a common place, so each
connector can use it while they're being converted.
Implement the properties required for the connectors:
- scaling mode property
- force audio property
- broadcast rgb
- aspect ratio
While at it, make clear that intel_digital_connector_atomic_get_property
is a hack that has to be removed when all connector properties
are converted to atomic.
Changes since v1:
- Scaling mode and aspect ratio are partly handled in core now.
Changes since v2:
- Split out the scaling mode / aspect ratio changes to a preparation
patch.
- Use mode_changed for panel fitter, changes to this property
are checked by fastset.
- Allowed_scaling_modes is removed, handled through core now.

Here are some serial and tty fixes for 4.12-rc3. They are a bit
"bigger" than normal, which is why I had them "bake" in linux-next for a
few weeks and didn't send them to you for -rc2.
They revert a few of the serdev patches from 4.12-rc1, and bring things
back to how they were in 4.11, to try to make things a bit more stable
there. Rob and Johan both agree that this is the way forward, so this
isn't people squabbling over semantics. Other than that, just a few
minor serial driver fixes that people have had problems with.
All of these have been in linux-next for a few weeks with no reported

Interrupts should not be enabled at this early in the boot process. It is
also fine to leave interrupts enabled during this time as there's only one
CPU running, and on_each_cpu() means to only run on the current CPU.
If early_boot_irqs_disabled is set, it is safe to run cpu_flush_range() with
interrupts disabled. Don't trigger a BUG_ON() in that case.

Add a testcase to test kprobes via ftrace interface
with many concurrent kprobe events.
This tries to add many kprobe events (up to 256) on
kernel functions. To avoid making ftrace-based
kprobes (kprobes on fentry), it skips first N bytes
(on x86 N=5, on ppc or arm N=4) of function entry.
After that, it enables all those events, disable it,
and remove it.
Since the unoptimization buffer reclaiming will
be delayed, after removing events, it will wait
enough time.

Fix kprobes to set(recover) RWX bits correctly on trampoline
buffer before releasing it. Releasing readonly page to

Without this fix, if kprobes user register a bunch of kprobes
in function body (since kprobes on function entry usually
use ftrace) and unregister it, kernel hits a BUG and crash.

Cong Wang attempted to add back rt->fi in commit
82486aa6f1 ("ipv4: restore rt->fi for reference counting")
but this proved to add some issues that were complex to solve.
Instead, I suggested to add a refcount to the metrics themselves,
being a standalone object (in particular, no reference to other objects)
I tried to make this patch as small as possible to ease its backport,
instead of being super clean. Note that we believe that only ipv4 dst
need to take care of the metric refcount. But if this is wrong,
this patch adds the basic infrastructure to extend this to other
families.
Many thanks to Julian Anastasov for reviewing this patch, and Cong Wang
for his efforts on this problem.

This fix addresses two problems in the way the DSCP field is formulated
on the encapsulating header of IPv6 tunnels.
Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=195661
1) The IPv6 tunneling code was manipulating the DSCP field of the
encapsulating packet using the 32b flowlabel. Since the flowlabel is
only the lower 20b it was incorrect to assume that the upper 12b
containing the DSCP and ECN fields would remain intact when formulating
the encapsulating header. This fix handles the 'inherit' and
'fixed-value' DSCP cases explicitly using the extant dsfield u8 variable.
2) The use of INET_ECN_encapsulate(0, dsfield) in ip6_tnl_xmit was
incorrect and resulted in the DSCP value always being set to 0.
Commit 90427ef5d2 ("ipv6: fix flow labels when the traffic class
is non-0") caused the regression by masking out the flowlabel
which exposed the incorrect handling of the DSCP portion of the
flowlabel in ip6_tunnel and ip6_gre.

sometimes ICMP replies to INIT chunks are ignored by the client, even if
the encapsulated SCTP headers match an open socket. This happens when the
ICMP packet is carried by a paged skb: use skb_header_pointer() to read
packet contents beyond the SCTP header, so that chunk header and initiate
tag are validated correctly.
v2:
- don't use skb_header_pointer() to read the transport header, since
icmp_socket_deliver() already puts these 8 bytes in the linear area.
- change commit message to make specific reference to INIT chunks.

There is a race condition in llc_ui_bind if two or more processes/threads
try to bind a same socket.
If more processes/threads bind a same socket success that will lead to
two problems, one is this action is not what we expected, another is
will lead to kernel in unstable status or oops(in my simple test case,
cause llc2.ko can't unload).
The current code is test SOCK_ZAPPED bit to avoid a process to
bind a same socket twice but that is can't avoid more processes/threads
try to bind a same socket at the same time.
So, add lock_sock in llc_ui_bind like others, such as llc_ui_connect.

We need to return an error for any call that asks for MSI / MSI-X
vectors only, so that non-trivial fallback logic can work properly.
Also valid dev->irq and use the "correct" errno value based on feedback
from Linus.

"A couple of fixes for the next rc on the nvme front. Various FC fixes
from James, controller removal fixes from Ming (including a block layer
patch), a APST related device quirk from Andy, a RDMA fix for small
queue depth device from Marta, as well as fixes for the lack of
metadata support in non-PCIe drivers and the printk logging format from
me."
Currently the timer is armed for 1ms after the first use and is killed
immediately, dropping the forcewake as early as possible. However, for
very frequent operations the forcewake dance has a large impact on
latency and keeping the timer alive until we are idle is preferred. To
achieve this, if we call intel_uncore_forcewake_get whilst the timer is
alive (repeated use), then set a flag to restart the timer on expiry
rather than drop the forcewake usage count. The timer is racy, the
consequence of the race is to expire the timer earlier than is now
desired but does not impact on correct behaviour. The offset the race
slightly, we set the active flag again on intel_uncore_forcewake_put.
The effect should be to reduce the jitter of reacquiring the fw every
1ms on a busy system. However, the cost is to keep the timer alive for
an extra 1ms on a nearly idle system. We chose to incur the jitter
previously to keep the timer off for as much as possible.
