Pull RCU updates from Ingo Molnar:
"The main RCU changes in this cycle are:
- the combination of tree geometry-initialization simplifications and
OS-jitter-reduction changes to expedited grace periods. These two
are stacked due to the large number of conflicts that would
otherwise result.
- privatize smp_mb__after_unlock_lock().
This commit moves the definition of smp_mb__after_unlock_lock() to
kernel/rcu/tree.h, in recognition of the fact that RCU is the only
thing using this, that nothing else is likely to use it, and that
it is likely to go away completely.
- documentation updates.
- torture-test updates.
- misc fixes"

The biggest changes in the core this time around have been some
refactorings that move us towards being able to drop the list of
regulators maintained by the core and instead just use the driver model
list maintained for the class devices for regulators which will make the
code smaller and avoid some potential bugs. Otherwise another fairly
quiet release for the regulator API, highlights include:
- A new API for setting voltages based on a minimum, target, maximum
triplet.
- Support for continuous voltage ranges rather than tables of explicit
steps in the PWM regulator, requiring less explicit configuration.
- New driver support for Dialog DA9215, Maxim 77843, Mediatek MT6311
and Qualcomm RPM.

DSA port configuration and status
This patchset allows various switch port settings to be configured and
port status to be sampled. Some of these patches have been posted
before.
The first three patches provide infrastructure for configuring a
switch ports link speed and duplex from a fixed_link phy.
Patch four then uses this infrastructure to allow the CPU and DSA
ports of a switch to be configured using a fixed-link property in the
device tree.
Patches five and six allow a phy-mode property to be specified in the
device tree, and allow this to be used for configuring RGMII delays.
Patches seven through nine allow link status, for example that of an
SFP module, to be read from a gpio.

What features a phy supports is masked in genphy_config_init() by
looking at the PHYs BMSR register.
If the link is down, fixed_phy_update_regs() will only set the auto-
negotiation capable bit in BMSR. Thus genphy_config_init() comes to
the conclusion the PHY can only perform 10/Half, and masks out the
higher speed features. If however the link it up, BMSR is set to
indicate the speed the PHY is capable of auto-negotiating, and
genphy_config_init() does not mask out the high speed features.
To fix this, when the link is down, have fixed_phy_update_regs() leave
the link status, auto-negotiation complete, and link partner
capabilities unset, but set all the local capabilities depending on
the fixed phy speed.

Some Ethernet MAC drivers using the PHY library require the hardcoding
of link parameters when interfaced to a switch device, SFP module,
switch to switch port, etc. This has typically lead to various ad-hoc
implementations looking like this:
- using a "fixed PHY" emulated device, which will provide link
indication towards the Ethernet MAC driver and hardware
- pretend there is no PHY and hardcode link parameters, ala mv643x_eth
Based on that, it is desireable to have the PHY drivers advertise the
correct link parameters, just like regular Ethernet PHYs towards their
CPU Ethernet MAC drivers, however, Ethernet MAC drivers should be able
to tell whether this link should be monitored or not. In the context
of an Ethernet switch, SFP module, switch to switch link, we do not
need to monitor this link since it should be always up.

This patch modifies the -I/--int-regs option to enablepassing the name
of the registers to sample on interrupt. Registers can be specified by
their symbolic names. For instance on x86, --intr-regs=ax,si.
The motivation is to reduce the size of the perf.data file and the
overhead of sampling by only collecting the registers useful to a
specific analysis. For instance, for value profiling, sampling only the
registers used to passed arguements to functions.
With no parameter, the --intr-regs still records all possible registers
based on the architecture.
To name registers, it is necessary to use the long form of the option,
i.e., --intr-regs:
$ perf record --intr-regs=si,di,r8,r9 .....
To record any possible registers:
$ perf record -I .....
$ perf report --intr-regs ...
To display the register, one can use perf report -D
To list the available registers:
$ perf record --intr-regs=\?
available registers: AX BX CX DX SI DI BP SP IP FLAGS CS SS R8 R9 R10 R11 R12 R13 R14 R15

Before this patch there's no way to connect a loaded bpf object

Fortunately, at this time there's only one user of it (perf test LLVM),
so we change it together.

tcp: receive-side per route dctcp handling
Original cover letter:
Currently, the following case doesn't use DCTCP, even if it should:
- responder has f.e. cubic as system wide default
- 'ip route congctl dctcp $src' was set
Then, DCTCP is NOT used if a DCTCP sender attempts to connect from a
host in the $src range: ECT(0) is set, but listen_sk is not dctcp, so
we fail the INET_ECN_is_not_ect sanity check.
We also have to examine the dst used for the SYN/ACK reply to make
this case work.
In order to minimize additional cost, store the 'ecn is must have'
information is the dst_features field.
The set targets -next instead of -net since this doesn't seem to be a
serious bug and to give the change more soak time until it hits linus
tree.

Currently, the following case doesn't use DCTCP, even if it should:
A responder has f.e. Cubic as system wide default, but for a specific
route to the initiating host, DCTCP is being set in RTAX_CC_ALGO. The
initiating host then uses DCTCP as congestion control, but since the
initiator sets ECT(0), tcp_ecn_create_request() doesn't set ecn_ok,
and we have to fall back to Reno after 3WHS completes.
We were thinking on how to solve this in a minimal, non-intrusive
way without bloating tcp_ecn_create_request() needlessly: lets cache
the CA ecn option flag in RTAX_FEATURES. In other words, when ECT(0)
is set on the SYN packet, set ecn_ok=1 iff route RTAX_FEATURES
contains the unexposed (internal-only) DST_FEATURE_ECN_CA. This allows
to only do a single metric feature lookup inside tcp_ecn_create_request().

non-zero.

Currently tun-info options pointer is used in few cases to
pass options around. But tunnel options can be accessed using
ip_tunnel_info_opts() API without using the pointer. Following
patch removes the redundant pointer and consistently make use
of API.

There were two cases where dm_cell_visit_release() was being called,
which removes the cell from the prison's rbtree, but the callers didn't
also return the cell to the mempool. Fix this by having them call
free_prison_cell().
This leak manifested as the 'kmalloc-96' slab growing until OOM.
