We don't need to look at modules in dsos__findnew because the
kernel events come only with user DSOs. Also we need a way to
list just the module DSOs so that we can create multiple sets of
maps, now that we will support maps for the variables in a
symtab.

The comment in fuse_open about O_DIRECT:
"VFS checks this, but only _after_ ->open()"
also holds for fuse_create, however, the same kind of check was missing there.
As an impact of this bug, open(newfile, O_RDWR|O_CREAT|O_DIRECT) fails, but a
stub newfile will remain if the fuse server handled the implied FUSE_CREATE
request appropriately.
Other impact: in the above situation ima_file_free() will complain to open/free
imbalance if CONFIG_IMA is set.

The commit fe3e78e073d25308756f38019956061153267769
ASoC: Factor out snd_soc_init_card()
removed the error paths that are still valid for wm97* codecs, causing
the compile errors like
sound/soc/codecs/wm9705.c:399: error: label 'reset_err' used but not defined
sound/soc/codecs/wm9712.c:687: error: label 'reset_err' used but not defined
sound/soc/codecs/wm9713.c:1237: error: label 'reset_err' used but not defined
Revert the removed error path codes.

This patch introduces a list to each protection domain which

This patch adds a reference count to each device to count
how often the device was bound to that domain. This is
important for single devices that act as an alias for a
number of others. These devices must stay bound to their
domains until all devices that alias to it are unbound from
the same domain.

This patch changes IOMMU code to use dev->archdata->iommu to

With the previous changes the get_device_resources function
can be simplified even more. The only important information
for the callers is the protection domain.
This patch renames the function to get_domain() and let it
only return the protection domain for a device.

If there is no domain associated to a device yet and the
device has an alias device which already has a domain, the
original device needs to have the same domain as the alias
device.
This patch changes domain_for_device to handle this
situation and directly assigns the alias device domain to
the device in this situation.

Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>

This patch extends the iommu_flush_pages function to flush
the TLB entries on all IOMMUs the domain has devices on.
This basically gives up the former assumption that dma_ops
domains are only bound to one IOMMU in the system.
For dma_ops domains this is still true but not for
IOMMU-API managed domains. Giving this assumption up for
dma_ops domains too allows code simplification.
Further it splits out the main logic into a generic function
which can be used by iommu_flush_tlb too.

This is recreated driver for the FM module found on Miro
PCM20 sound cards. This driver was removed around the 2.6.2x
kernels because it relied on the removed OSS module. Now, it
uses a current ALSA module (snd-miro) and is adapted to v4l2
layer.
It provides only basic functionality: frequency changing and
FM module muting.

STAC/IDT codecs seem to behave weird when SET_PIN_SENSE verb is issued
before reading the jack-detection although the TRIG_REQ pin capability
is given by the hardware.
Since snd_hda_jack_detect() issues the SET_PIN_SENSE verb simply judging
from the pincap, we have to revert the change in the commit
d56757abc11a21996d9839c0d4e3b2c3666cd318
ALSA: hda - Replace the rest of jack-detections with snd_hda_jack_detect()
to plain GET_PIN_SENSE verb without triggering.

The non-cohernet PPC arch doesn't give the correct address by a simple
virt_to_page() for pages allocated via dma_alloc_coherent().
This patch adds a hack to fix the conversion similarly like MIPS.
Note that this doesn't fix perfectly: the pages should be marked with
proper pgprot value. This will be done in a future implementation like
the conversion to dma_mmap_coherent().

The non-coherent MIPS arch doesn't give the correct address by a simple
virt_to_page() for pages allocated via dma_alloc_coherent().
Original patch by Wu Zhangjin <wuzj@lemote.com>.
[Ralf mentioned: "The origins of this patch go back far further.
The oldest patch I could find which is a superset of this was written
by Atsushi Nemoto and various incarnations of it have been sumitted
to and reject by me a number of times through the years."]
A proper check of the buffer allocation type was added to avoid the
wrong conversion.
Note that this doesn't fix perfectly: the pages should be marked with
proper pgprot value. This will be done in a future implementation like
the conversion to dma_mmap_coherent().
