700163db3d l2tp: correctly handle ancillary data in the ip6 recv path
l2tp_ip6 is incorrectly using the IPv4-specific ip_cmsg_recv to handle
ancillary data.  This means that socket options such as IPV6_RECVPKTINFO are
not honoured in userspace.

Convert l2tp_ip6 to use the IPv6-specific handler.

8e72d37eb3 ipv6: export ip6_datagram_recv_ctl
ip6_datagram_recv_ctl and ip6_datagram_send_ctl are used for handling IPv6
ancillary data.  Since ip6_datagram_send_ctl is already publicly exported for
use in modules, ip6_datagram_recv_ctl should also be available to support
ancillary data in the receive path.

73df66f8b1 ipv6: rename datagram_send_ctl and datagram_recv_ctl
The datagram_*_ctl functions in net/ipv6/datagram.c are IPv6-specific.  Since
datagram_send_ctl is publicly exported it should be appropriately named to
reflect the fact that it's for IPv6 only.

999517f674 staging:iio: Remove noop call to __iio_update_buffer
__iio_update_buffer updates the buffer's bytes_per_datum and length fields.
But the only user of this function just passes in these exact fields, so the
call basically looks like this:

	buffer->bytes_per_datum = buffer->bytes_per_datum;
	buffer->length = buffer->length;

Which means it is a noop and can be removed. Also remove the function itself,
since it is now unused.

3484aac161 net/mlx4_en: Fix transmit timeout when driver restarts port
Under heavy CPU load, changing, ring size/mtu/etc. could result in transmit
timeout, since stop-start port might take more than 10 seconds.
Calling netif_detach_device to prevent tx queue transmit timeout.

netif_detach_device() is not called under ndo_stop, because netif_carrier_off
will prevent the timeout, and device should not be marked as not present, or
else user won't be able to start it later on.

0c3c22f9c5 ARM: OMAP AM33XX: clock data: SET_RATE_PARENT in lcd path
LCDC clock node is a one that does not have set rate capability. It
just passes on the rate that is sent downstream by it's parent. While
lcdc clock parent and it's grand parent - dpll_disp_m2_ck and
dpll_disp_ck has the capability to configure rate.

And the default rates provided by LCDC clock's ancestors are not
sufficient to obtain pixel clock for current LCDC use cases, hence
currently display would not work on AM335x SoC's (with driver
modifications in platfrom independent way).

Hence inform clock framework to propogate set rate for LCDC clock as
well as it's parent - dpll_disp_m2_ck. With this change, set rate on
LCDC clock would get propogated till dpll_disp_ck via dpll_disp_m2_ck,
hence allowing the driver (same driver is used in DaVinci too) to set
rates using LCDC clock without worrying about platform dependent clock
details.

2ac3634a7e perf: Document the ABI of perf sysfs entries
This patchset addes two new sets of files to sysfs for POWER architecture.

	- perf event config format in /sys/devices/cpu/format/event
	- generic and POWER-specific perf events in /sys/devices/cpu/events/

The format of the first file is already documented in:

	sysfs-bus-event_source-devices-format

Document the format of the second set of files '/sys/devices/cpu/events/*'
which would also become part of the ABI.

Changelog[v4]:
	[Jiri Olsa]: Mention that multiple event= like terms can be specified
	in the 'events' file.
	[Jiri Olsa]: Remove the documentation for the 'config format' file
	as it is already documented in 'Documentation/ABI/testing/'.
	[Jiri Olsa]: Move ABI documentation from 'stable/' to 'testing/'

Changelog[v3]:
	[Greg KH] Include ABI documentation.

2663960c15 perf: Make EVENT_ATTR global
Rename EVENT_ATTR() to PMU_EVENT_ATTR() and make it global so it is
available to all architectures.

Further to allow architectures flexibility, have PMU_EVENT_ATTR() pass
in the variable name as a parameter.

Changelog[v2]
	- [Jiri Olsa] No need to define PMU_EVENT_PTR()

00c7e1f10c perf report: Add report.group config option
Add report.group config option for setting default value of event
group view.  It affects the report output only if perf.data contains
event group info.

A user can write .perfconfig file like below to enable group view by
default:

  $ cat ~/.perfconfig
  [report]
  group = true

And it can be disabled through command line:

  $ perf report --no-group

717e263fc3 perf report: Show group description when event group is enabled
When using event group viewer, it's better to show the group description
rather than the leader information alone.

If a leader did not contain any member, it's a non-group event.
