====================
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.
Changes since v1:
Rewrite 9/9 so that it hopefully does not regression on

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.

By default, DSA and CPU ports are configured to the maximum speed the

The current code sets user ports to perform auto negotiation using the
phy. CPU and DSA ports are configured to full duplex and maximum speed
the switch supports.
There are however use cases where the CPU has a slower port, and when
user ports have SFP modules with fixed speed. In these cases, port
settings to be read from a fixed_phy devices. The switch driver then
needs to implement the adjust_link op, so the port settings can be
set.

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
to its source file. However, during applying perf's '--filter' to BPF
object, without this connection makes things harder, because perf loads
all programs together, but '--filter' setting is for each object.
The API of bpf_object__open_buffer() is changed to allow passing a name.
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.
v1 -> v2:
- Addressed Dave's feedback, not exposing any bits to user space
- Added patch 3 to reject incorrect configurations
- Rest as is, rebased and retested

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().

Pull char/misc driver patches from Greg KH:
"Here's the "big" char/misc driver update for 4.3-rc1.
Not much really interesting here, just a number of little changes all
over the place, and some nice consolidation of the nvmem drivers to a
common framework. As usual, the mei drivers stand out as the largest
"churn" to handle new devices and features in their hardware.
All have been in linux-next for a while with no issues"

Pull kvm updates from Paolo Bonzini:
"A very small release for x86 and s390 KVM.
- s390: timekeeping changes, cleanups and fixes
- x86: support for Hyper-V MSRs to report crashes, and a bunch of
cleanups.
One interesting feature that was planned for 4.3 (emulating the local
APIC in kernel while keeping the IOAPIC and 8254 in userspace) had to
be delayed because Intel complained about my reading of the manual"

User visible changes:
- Add new compaction-times python script. (Tony Jones)
- Make the --[no-]-demangle/--[no-]-demangle-kernel command line

structure with the environment where some perf data was
collected in functions not necessarily related to perf.data
file processing. (Kan Liang)
- Cleanups for the tracepoint definition location paths routines. (Jiri Olsa)
- Introduce sysfs/filename__sprintf_build_id, removing code
duplication. (Masami Hiramatsu)
