Since the DMA controller clocks are managed at amba bus level, the
PL330 device clocks handling has been removed from the driver in
commit 7c71b8eb("DMA: PL330: Remove redundant runtime_suspend/
resume functions")
However, this left the S5PV210 platform with only clkdev entries
linking "apb_pclk" clock conn_id to a dummy clock, rather than
to corresponding platform PL330 DMAC clock.
As a result the DMA controller is now attempted to be used on
S5PV210 with the clock disabled and the driver fails with an
error:
dma-pl330 dma-pl330.0: PERIPH_ID 0x0, PCELL_ID 0x0 !
dma-pl330: probe of dma-pl330.0 failed with error -22
dma-pl330 dma-pl330.1: PERIPH_ID 0x0, PCELL_ID 0x0 !
dma-pl330: probe of dma-pl330.1 failed with error -22
Fix this by adding "apb_pclk" clkdev entries for the Peripheral
DMA controllers 0/1 and removing the dummy apb_pclk clock.

This patch (as1661) fixes a rather obscure bug in ehci-hcd. In a
couple of places, the driver compares the DMA address stored in a QH's
overlay region with the address of a particular qTD, in order to see
whether that qTD is the one currently being processed by the hardware.
(If it is then the status in the QH's overlay region is more
up-to-date than the status in the qTD, and if it isn't then the
overlay's value needs to be adjusted when the QH is added back to the
active schedule.)
However, DMA address in the overlay region isn't always valid. It
sometimes will contain a stale value, which may happen by coincidence
to be equal to a qTD's DMA address. Instead of checking the DMA
address, we should check whether the overlay region is active and
valid. The patch tests the ACTIVE bit in the overlay, and clears this
bit when the overlay becomes invalid (which happens when the
currently-executing URB is unlinked).

This patch (as1660) works around a hardware problem present in some
(if not all) Intel EHCI controllers. After a QH has been unlinked
from the async schedule and the corresponding IAA interrupt has
occurred, the controller is not supposed access the QH and its qTDs.
There certainly shouldn't be any more DMA writes to those structures.
Nevertheless, Intel's controllers have been observed to perform a
final writeback to the QH's overlay region and to the most recent qTD.
For more information and a test program to determine whether this
problem is present in a particular controller, see
http://marc.info/?l=linux-usb&m=135492071812265&w=2http://marc.info/?l=linux-usb&m=136182570800963&w=2
This patch works around the problem by always waiting for two IAA
cycles when unlinking an async QH. The extra IAA delay gives the
controller time to perform its final writeback.
Surprisingly enough, the effects of this silicon bug have gone
undetected until quite recently. More through luck than anything
else, it hasn't caused any apparent problems. However, it does
interact badly with the path that follows this one, so it needs to be
addressed.

virtio_rng feeds the randomness buffer handed by the core directly
into the scatterlist, since commit bb347d9807.
However, if CONFIG_HW_RANDOM=m, the static buffer isn't a linear address
(at least on most archs). We could fix this in virtio_rng, but it's actually
far easier to just do it in the core as virtio_rng would have to allocate
a buffer every time (it doesn't know how much the core will want to read).

There are several bugs at error path of create_snapshot() when the
transaction commitment failed.
- access the freed transaction handler. At the end of the
transaction commitment, the transaction handler was freed, so we
should not access it after the transaction commitment.
- we were not aware of the error which happened during the snapshot
creation if we submitted a async transaction commitment.
- pending snapshot access vs pending snapshot free. when something
wrong happened after we submitted a async transaction commitment,
the transaction committer would cleanup the pending snapshots and
free them. But the snapshot creators were not aware of it, they
would access the freed pending snapshots.
This patch fixes the above problems by:
- remove the dangerous code that accessed the freed handler
- assign ->error if the error happens during the snapshot creation
- the transaction committer doesn't free the pending snapshots,
just assigns the error number and evicts them before we unblock
the transaction.

them appears to have ended up in the gpmc_calc_timings() function and
hence, this is causing problems requesting chip-selects. Fix this merge

Setting net.ipv6.conf.<interface>.accept_ra=2 causes the kernel
to accept RAs even when forwarding is enabled. However, enabling
forwarding purges all default routes on the system, breaking
connectivity until the next RA is received. Fix this by not
purging default routes on interfaces that have accept_ra=2.
