[PATCH 0/7] linux-yocto*: consolidated pull request

[Bruce Ashfield]

Richard/Saul,

Here's the next round of linux-yocto* changes for the 1.7 release. The 
notable update here, is the introduction of the 3.17-rcX kernel via both
linux-yoct-dev and a named recipe (which uses the same -dev tree for
now).

I've built and booted all the qemu BSPs on this tree, using the kernel-dev
image type. 

The fixes required from that testing are the lttng and perf commits. I'll
drop the perf commit once a fix is available via the upstream kernel. I 
tested both the perf and lttng updates on older and newer kernels without
any issues.

I'm on the road for the next three days, but wanted to get this out for
a preview before being a bit unresponsive, and to let others apply and build
these if they want.

I've done my best here, but I expect we'll find something in the broader
testing.

Cheers,

Bruce

+Subject: [PATCH 1/3] Fix: noargs probes should calculate alignment and event
+ length
+
+A noargs probe could have event fields. noargs just means that the probe
+does not receive any argument as parameter. However, it could very well
+serialize data into fields (global variables, constants, etc).
+
+It just happens that LTTng does not serialize any data in noargs events
+at the moment, but this may very well change.
+
+The if (0) with (void) variable access strategy to stop compiler from
+complaining from unused variables does not seem to work as expected with
+gcc 4.9.1. Use "unused" attribute instead.

[PATCH 3/7] perf: fix v3.17 powerpc compilation issues

[Bruce Ashfield]

The powerpc perf arch port has two issues in the current 3.17-rc
seriers. Undefined dwarf symbols and undefined pr_debug calls.

commit a60335ba [perf tools powerpc: Adjust callchain based on DWARF debug info]
introduces skip-callchain-idx.c, and breaks the perf build.

Unitl fixes get into the mainline kernel, we temporarily fix the issues by
adding a forced linke to -ldw and modifying skip-callchain-idx.c to include
the proper debug files for pr_debug.
