Richard/Saul,
Here are three fixes for the upcoming RCs and release. Once is a new branch, but
has zero impact on existing boards, so I've gone ahead and added it for this
upcoming release. The other two are bug fixes.
[PATCH 1/3] linux-yocto/3.8: add haswell-wc board config and branch
Bumping the meta branch SRCREV to import the following board support:
meta: add haswell-wc bsp for Intel Haswell Platform (Walnut Canyon CRB)
scc and config files
[PATCH 2/3] linux-yocto/3.10: mips configuration changes
Updating the 3.10 SRCREV to import the following MIPS configuration changes
4f689aa meta: remove ftrace/ftrace-disable feature
3058d81 mips: have the mips BSPs disable function tracing instead of
ftrace
935f43f meta: add ftrace/ftrace-function-tracer-disable feature
0d72a03 mti-malta64: Default to support o32 and n32 userspace binaries
The first three changes improve the ftrace disabling fragments, to allow
tracepoints
and ftrace to be enabled, while only disabling dynamic ftrace. This allows
tools
that required tracepoints (like lttng) to be built against MIPS.
The mti-malta64 change adds n32 and o32 support to the default configuration
to
support a broader range of userspace binaries.

[PATCH 3/3] linux-yocto/3.10: fix long perf compile times
perf's builtin-sched.c triggers extremly long build times on some
architectures due to gcc 4.7+ var-tracking functionality.
To fix this, we can cherry pick the 3.12 commit:
f36f83f94 [perf sched: Move struct perf_sched definition out of
cmd_sched()]
With this change build times are reduced from 15 to 20 minutes for qemuarm
to:
real 2m19.940s
user 1m35.438s
sys 0m11.165s
For kernel's that are not carrying this patch, the following can be added
to the perf recipe to also fix the issue:
+++ b/meta/recipes-kernel/perf/perf.bb

Bruce
