The set includes one rare memory leak and some cleanup. It also includes a new frontend for the libertas driver. It is going via my tree because of interdependencies between my tree and the libertas/netdev tree.

Yeah, gnome-terminal damage. But you need to git it from the repo to

It is too late for a repull.  Linus' main branch already contains your 
previous incarnation, so you must publish a fix separately to go on top.

There seems to be some breakage here:

	drivers/mmc/core/host.c: In function ‘mmc_remove_host’:
	drivers/mmc/core/host.c:146: error: implicit declaration of function ‘led_trigger_unregister’
	drivers/mmc/core/host.c:146: error: ‘struct mmc_host’ has no member named ‘led’

this was after doing a few "make randconfig" runs, a habit I'm trying to 
encourage (and do myself occasionally too).

Linus, please pull from

Lot's of changes in here. Mostly it is SDIO and SPI support, although there are things like removal of MMC layer specific error codes.

Whatever happened, I certainly knew nothing about MMC back then, and I 
did a less than appropriate job at reviewing the patch.

I'm getting far more involved with MMC/SD/SDIO now so this issue will 
get properly resolved.

That's not correct.  Just as today, it's entirely trackable.  We've had
the sign-off thing for quite a long time, and we've also had the ARM
patch system for ages.  That's what the "2271/3" number means.

Your name popped up on the commit for this, but as that was during the

I would think that it would be better to look at just MMC_RSP_136 and
MMC_RSP_CRC in case we get future variations.

Actually, I'm not the author of this workaround.  And looking at it 
closer, the current workaround is utterly buggy as it completely inhibit 
CRC error reporting for everything but the listed commands when the MSB 
of the response is a zero.

Indeed.

Please apply the following patch.  It is compile tested only as I don't 
have PXA27x hardware with MMC at the moment, but it just cannot be worse 
than the current code even when it was compiling.

Well... I used to.

But the only MMC capable PXA hardware in working conditions I have 
access to at the moment is PXA255 based which doesn't suffer from this 
erratum.

People in better position than I currently do to test a fix are most

Hi Nicolas,

You seem to be the source of this workaround, and also the maintainer of
PXA. So I guess this falls into your lap either way. Highlights from my

Nope.  Suggest checking the git logs and contacting those who authored
the change.

I've read through the erratum, and to me it seems like the bug affects
all long replies, not just these codes. So I think the code should be
fixed to look at the response flag, not the opcode.

Do you have hardware so that you can test such a change?

AFAIK, an atomic_t doesn't guarantee any ordering, just atomicity. So an
atomic_t with a barrier would be sufficient. But barriers are mostly
voodoo that few people understand ;)

Sounds to me like either struct xyz_host { atomic_t removed; } would do
the job, or that actually wider regions of mmc_host_remove() and
mmc_detect_change() need to be serialized.

The host->removed member is only used for this simple test. It is set in
mmc_host_remove() to indicate that the removal process has begun. At
this point it is invalid to call mmc_detect_change() (the place this
patch fixes). So the spinlocks are mostly there so that things are
properly ordered when we go SMP. Some creative barriers would probably
work as well, but I find spinlocks more "normal" and hence more readable.

If you want to ensure you always only modify host->removed from under
the spinlock, it would be enforcable by introducing an accessor function
and doing a BUG_ON(!spin_is_locked()) in there.

If you just want to ensure that host->removed is 0 at this point, you
shouldn't need any spinlocks AFAIKS... that way you can probably afford
to move it out from CONFIG_MMC_DEBUG and get wider testing.

It makes sure we don't have any race when it comes to modifying
host->removed. We had some problems where controllers reported card
insertion events even after they'd signaled to be removed, causing all
kind of odd problems. This check was added to easier spot it should it
arise again.
