hi,
sending changes to enable group read of perf counters
for perf stat command. It allows us to read whole group
of counters within single read syscall.
v2 changes:
- fixed release segfault reported by Arnaldo
- rebased to latest Arnaldo's perf/core
- patch 1 already merged in
Also
Currently we use the size of struct perf_counts_values
to read the event, which prevents us to put any new
member to the struct.
Adding perf_evsel__read_size to return size of the
buffer needed for event read.
Link: http://lkml.kernel.org/n/tip-cfc3dmil3tlzezzxtyi9f...@git.kernel.org
Make perf stat use group read if there are groups
defined. The group read will get the values for all
member of groups within a single syscall instead of
calling read syscall for every event.
We can see considerable less amount of kernel cycles
spent on single group read, than reading each
Adding perf_evsel__read_counter function to read single or
group counter. After calling this function the counter's
evsel::counts struct is filled with values for the counter
and member of its group if there are any.

The CX9020 differs from i.MX53 Quick Start Board by:
- use uart2 instead of uart1
- DVI-D connector instead of VGA
- no audio
- no SATA connector
- CCAT FPGA connected to emi
- enable rtc
v5:
- rebased on v4.13-rc2
- don't take maintainership for imx53-cx9020.dtsi, keep it

Fair enough. Acked-by-me.

Traditionally, the OOM killer is operating on a process level.
Under oom conditions, it finds a process with the highest oom score
and kills it.
This behavior doesn't suit well the system with many running
containers:

Introduce a per-memory-cgroup oom_priority setting: an integer number
within the [-1, 1] range, which defines the order in which
the OOM killer selects victim memory cgroups.
OOM killer prefers memory cgroups with larger priority if they are

First, separate tsk_is_oom_victim() and TIF_MEMDIE flag checks:
let the first one indicate that a task is killed by the OOM killer,
and the second one indicate that a task has an access to the memory
reserves (with a hope to eliminate it later).
Second, set TIF_MEMDIE to all threads of an OOM
