Isn't it already in powerpc-next about to be pulled by Linus ?
In general, I recommend you check the status of your patches on
patchwork. I'm nagging Jeremy to add a feature so it emails the
submitter when the patch status changes :-)
Cheers,
Ben.

* [git pull] Please pull powerpc.git next branch
From: Benjamin Herrenschmidt @ 2010-08-05 1:46 UTC (permalink / raw)
To: Linus Torvalds; +Cc: linuxppc-dev list, Andrew Morton, Linux Kernel list
Hi Linus !
Here's the batch of powerpc stuff for this merge window. Not major highlight,
some work on 64-bit Book3E (embedded) by myself, and the powerpc part of the
HW breakpoint stuff by Mohan Kumar and Paulus, and the usual batch of embedded
bits and pieces.
This does -not- include my memblock rework, which is in a separate branch
that I'm still sorting out due to clashes with ARM and some typos breaking
sh and microblaze. I'm not sure whether I'll send that this merge window
or just stick it into -next as soon as it's over. Peter Anvin also has some
interesting ideas to rewrite the memblock core into something more suitable
for handling allocations and take over the world :-)
Cheers,
Ben.

I read this, but I still don't understand what it means. What does
"auto CMD12" mean? Are there other kinds of CMD12? Part of this
might be my ignorance about how eSDHC works, but it could be clearer.
Also, you can feel free to merge this patch with patch 1 in your
series. I makes sense to update the documentation and the driver at
the same time.

* [PATCH] asoc/multi-component: fsl: add support for disabled SSI nodes
From: Timur Tabi @ 2010-08-04 22:51 UTC (permalink / raw)
To: alsa-devel, linuxppc-dev, lrg, broonie, kumar.gala
Add support for adding "status = disabled" to an SSI node to incidate that it
is not wired on the board. This replaces the not-so-intuitive previous method
of omitting a codec-handle property.
Signed-off-by: Timur Tabi <timur@freescale.com>
---
Kumar, would you please ACK the device-tree portion of this patch? I want
it to go through the ALSA tree.

I believe this is still on Ben's list of things to look at. Between
then and now, I'll see if I can get Thomas to pick this up for the -RT
tree to keep RT functional on P7 in the mean-time.
A bit more debug info below.

Based on some of the debug suggestions from Milton:
A WARN_ON for (!irqs_disabled) after local_irq_restore() did not show
any hits. (while otherwise continuing to suffer from the tlb batching
troubles).
---><----
hard_irq_disable();
last = _switch(old_thread, new_thread);
local_irq_restore(flags);
WARN_ON(!irqs_disabled()); <<<<----------
#if defined(CONFIG_PPC64) && defined(CONFIG_PREEMPT_RT) && 1
if (hadbatch) {
batch = &__get_cpu_var(ppc64_tlb_batch);
batch->active = 1;
}
#endif
----><----
Another assortment of WARN_ONs in the arch_{enter,leave}_lazy_mmu_mode
functions. As Milton stated above, the check for batch->active on the
way into the arch_enter_* function did generate lots of hits, the other
warn_ons did not.
-----><-------
static inline void arch_enter_lazy_mmu_mode(void)
{
struct ppc64_tlb_batch *batch = &get_cpu_var(ppc64_tlb_batch);
//|-----WARN_ON(batch->active); /* lots of hits if enabled */
|-------WARN_ON(irqs_disabled()); /* nothing.... */

That's a bit outdated on the software side. Look under the nand_spl
directory in u-boot; you should see several boards to use as examples.
If possible, I suggest working with the latest upstream u-boot rather
than what comes with the BSP.
If you have further questions, ask at u-boot@lists.denx.de.

I've not looked at the details of this driver, but there are drivers
that do such. So dma-debug needs to be fixed anyway; you can't assume
that a DMA address that dma_map_single returned is passed to
dma_sync_single_for API.
