[PATCH 00/17][linux-yocto-3.0:meta] preempt-rt update (3.0.1-rt8 scc's)

[Darren Hart]

The following series adds the necessary scc files in support of preempt-rt
for the following machines. These have all been build tested, issues
are noted below.  A handful have been boot tested, also noted.
	sugarbay
	common-pc (boots)
	common-pc-64
	jasperforest
	fri2
	fishriver
	emenlow
	crownbay (boots)
	qemuarm (arm-versatile-926ejs, boots)
	qemumips (mti-malta32-be, panics on boot)
	qemuppc (boot hangs with lost interrupts for hda)
	routerstationpro (build fails)
	mpc8315e-rdb
	beagleboard (build fails)

Also included in the series are some preempt-rt related configuration
changes and a minor correction to a fix made for the mpc8315e-rdb compilation
breakage with -Os in the boot Makefile.

The accompanying linux-yocto-rt recipes will follow once these are committed,
and I have SRC_REVs to include in the recipes.

note: approximately 17 hadrosaurs were converted to electricity to complete
      the necessary test builds.
The following changes since commit c692a2320dd10c7f3ac89f474f4bdd302da56634:

[PATCH 01/17] meta/rt: use CONFIG_PREEMPT_RT_FULL for 3.0 kernels

[Darren Hart]

The 3.0 preempt-rt patches use CONFIG_PREEMPT_RT_FULL instead of
CONFIG_PREEMPT_RT. Without this fix, the preemmpt-rt kernels build
with CONFIG_PREEMPT_NONE.

[PATCH 15/17] mpc8315e-rdb: remove boot -Os patch which is now in base

[Darren Hart]

I asked for this patch to be pushed down to standard/base so
that it would be available in the preempt-rt build as well.
Turns out it would have been and now that I have the rt scc files
right, this patch was getting double applied and do_patch was
failing.

We can use this patch to remove it from the mpc8315 config, or
we can revert pushing it down into standard/base.

[PATCH 17/17] routerstationpro: remove CONFIG_PREEMPT* definitions

[Darren Hart]

The routerstationpro.cfg is a nearly complete .config and needs to be pruned.
Among a lot of other things, it defines various CONFIG_PREEMPT* settings
which conflict with the preempt-rt settings. Remove them as they should be
ktype policy, not bsp specific settings.

Ack'd. This is good data, and we'll pull this in, since
it improves the situation greatly. There is no guarantee
that -rt will build and boot on ALL bsps, so having some
non-functional boards is consistent with that approach.

I recall you mentioning that you'd open bugs for the issue,
and that is a good idea. We can use it to track any efforts
on this in the 1.1 and 1.1+ timeframe. We can disable
the support in recipe space, or in the kernel before 1.1
is released, if we don't get any of the issues you raise
addressed.

I just made a similar fix here, so we'll keep it pushed down, but
keep the patch validation step happy.

I'll put something in place when merging. It really isn't
very interesting, and is something that we can better describe
outside of commits if anyone is interested. So a free pass
on this one, and I'll do the tidyup.
