Hi,
I almost forgot that I have some libtraceevent patch left. ;) The
first three of them are acked by Steven and the last is a port of a
recent perf patch from Kirill that handles a strerror_r build warning.
Please consider applying.

The pevent_strerror() sets @buf to a string that describes the

In small high zone(ex, 40M movable zone), reclaim priority

kswapd sleep unnecessarily so process ends up entering into direct

If higher zone is very small, priority could be raised easily
while lower zones have enough free pages. When one of lower zones
doesn't meet high watermark, the zone try to reclaim pages with

It ends up reclaiming excessive pages. I saw 8~1

The old driver has two main deficencies:
i) No repeated start (Sr) condiction is possible, this makes it unusable

This is the port of uprobes to powerpc. Usage is similar to x86.
[root@ ~]# ./bin/perf probe -x /lib64/libc.so.6 malloc
Added new event:
probe_libc:malloc(on 0xb4860)
You can now use it in all perf tools, such as:

Adds a new driver *omap-ocp2scp*. This driver takes the responsibility of
creating all the devices that is connected to OCP2SCP. In the case of OMAP4,
USB2PHY is connected to ocp2scp.
This also includes device tree support for ocp2scp driver and
the documentation with device tree binding informati
This patch series has been lying here for long. If no one has any
comments on this patch series, can someone pick it up?
This patch series is done as a preparatory step for adding phy drivers
for dwc3 and musb.
This series adds a new driver for ocp2scp (only dt) to which phy

Hi Steven,
The following patch set provides a feature which can read trace data of a guest
using virtio-trace (https://lkml.org/lkml/2012/8/9/210) for a recorder
function of trace-cmd. This patch set depends on the trace-agent running on a
guest in the virtio-trace system.

Use TRACE_DIR environment variable for setting
debugfs/tracing directory if defined. This is
for controlling guest(or remote) ftrace.

Add read path and control path to use trace-agent of virtio-trace.
When we use trace-agent, trace-cmd will be used as follows:
# AGENT_READ_DIR=/tmp/virtio-trace/tracing \

TRACING_DIR=/tmp/virtio-trace/debugfs/tracing \

Add non-blocking option for open() and splice_read() for avoiding block to read
trace data of a guest from FIFO.
If SIGINT comes to read/write processes from the parent process in the case
where FIFO as a read I/F is assigned, then reading is normally blocked for
splice_read(). So, we added nonblo
