The core ptrace access checking routine holds a task lock, and when
reporting a failure, Yama takes a separate task lock. To avoid a
potential deadlock with two ptracers taking the opposite locks, do not
use get_task_comm() and just use ->comm directly since accuracy is not
important for the report.

The current implementation of synchronise_count_{master,slave} blocks
slave CPUs in early boot until all of them come up. This no longer
works because blocking a CPU with interrupts off after notifying the
CPU to be online causes problems with the current kernel.
Specifically, after the workqueue changes
(commit a08489c569 "Pull workqueue changes from Tejun Heo")
the CPU_ONLINE notification callback workqueue_cpu_up_callback()
will hang on wait_for_completion(&idle_rebind.done), if the slave
CPUs are blocked for synchronize_count_slave().
The changes are to update synchronize_count_{master,slave}() to handle
one CPU at a time and to call synchronise_count_master() in __cpu_up()
so that the CPU_ONLINE notification goes out only after the COP0 COUNT
register is synchronized.

BCM6338 and BCM6348 have a message control register width of 8 bits, instead
of 16-bits like what the SPI driver assumes right now. Also the SPI message
type shift value of 14 is actually 6 for these SoCs.
This resulted in transmit FIFO corruption because we were writing 16-bits
to an 8-bits wide register, thus spanning on the first byte of the transmit
FIFO, which had already been filed in bcm63xx_spi_fill_txrx_fifo().
Fix this by passing the message control register width and message type
shift through platform data back to the SPI driver so that it can use
it properly.

Without this udelay(1) PCI idsel does not work correctly on the
"singleboard" (T-Mobile Surfbox) for the MiniPCI device. The result is
that PCI configuration fails and the MiniPCI card is not detected
correctly. Instead of
PCI host bridge to bus 0000:00
pci_bus 0000:00: root bus resource [mem 0x40000000-0x4fffffff]
pci_bus 0000:00: root bus resource [io 0x1000-0xffff]
pci 0000:00:03.0: BAR 0: assigned [mem 0x40000000-0x4000ffff]
pci 0000:00:00.0: BAR 0: assigned [mem 0x40010000-0x40010fff]
pci 0000:00:00.1: BAR 0: assigned [mem 0x40011000-0x40011fff]
We see only the CardBus device:
PCI host bridge to bus 0000:00
pci_bus 0000:00: root bus resource [mem 0x40000000-0x4fffffff]
pci_bus 0000:00: root bus resource [io 0x1000-0xffff]
pci 0000:00:00.0: BAR 0: assigned [mem 0x40000000-0x40000fff]
pci 0000:00:00.1: BAR 0: assigned [mem 0x40001000-0x40001fff]
Later the device driver shows this error:
ath5k 0000:00:03.0: cannot remap PCI memory region
ath5k: probe of 0000:00:03.0 failed with error -5
I assume that the logic chip which usually supresses the signal to the CardBus
card has some settling time and without the delay it would still let the
Cardbus interfere with the response from the MiniPCI card.
What I cannot explain is why this behaviour shows up now and not in earlier
kernel versions before. Maybe older PCI code was slower?

Both the CIU and GPIO interrupt domains were somewhat screwed up.
For the CIU domain, we need to call irq_domain_associate() for each of
the preassigned irq numbers. For the GPIO domain, we were applying
the register bit offset in octeon_irq_gpio_xlat, but it should be done
in octeon_irq_gpio_map instead.
Also: Reserve all 8 'core' irqs for the 'core' irq_chip so that they
don't get used by the other domains. Remove unused OCTEON_IRQ_*

As this is a special case for pscsi_parse_cdb() to call spc_parse_cdb() to
allow TCM to handle REPORT_LUN emulation, pscsi_plugin_task will have not
been allocated..
So now in pscsi_transport_complete() just check for existence of *pt and

We drop packet unconditionally when we fail to mirror it. This is not intended
in some cases. Consdier for kvm guest, we may mirror the traffic of the bridge
to a tap device used by a VM. When kernel fails to mirror the packet in
conditions such as when qemu crashes or stop polling the tap, it's hard for the
management software to detect such condition and clean the the mirroring
before. This would lead all packets to the bridge to be dropped and break the
netowrk of other virtual machines.
To solve the issue, the patch does not drop packets when kernel fails to mirror
it, and only drop the redirected packets.

Turns out these drivers had quite a wealth of minor bugs.
Also here are some build warning fixes for lm3533-als and

Final elements are a a div factor overflow and a warning

IIO fixes for v3.6-rc1
These mostly consist of fixes from Lars-Peter Clausen that were
the first part of a large series reworking the drivers concerned.
Turns out these drivers had quite a wealth of minor bugs.
Also here are some build warning fixes for lm3533-als and
adjd_s111 (both new drives in this cycle).
Final elements are a a div factor overflow and a warning
related fix in a couple of Analog Devices drivers.
All in all nothing major, but a worthwhile bunch of short
fixes.
Instead of using the private field xdr->p from struct xdr_stream,
use the public xdr_stream_pos().

Currently, we do not take into account the size of the 16 byte
struct nfs4_cached_acl header, when deciding whether or not we should
cache the acl data. Consequently, we will end up allocating an
8k buffer in order to fit a maximum size 4k acl.
This patch adjusts the calculation so that we limit the cache size
to 4k for the acl header+data.

Resetting the cursor xdr->p to a previous value is not a safe
practice: if the xdr_stream has crossed out of the initial iovec,
then a bunch of other fields would need to be reset too.
Fix this issue by using xdr_enter_page() so that the buffer gets
page aligned at the bitmap _before_ we decode it.
Also fix the confusion of the ACL length with the page buffer length
by not adding the base offset to the ACL length...

This allows distros to remove the line from their modprobe
configuration.

Some systems have a modprobe.d/nfs.conf file that sets an nfs4 alias
pointing to nfs.ko, rather than nfs4.ko. This can prevent the v4 module
from loading on mount, since the kernel sees that something named "nfs4"
has already been loaded. To work around this, I've renamed the modules
to "nfsv2.ko" "nfsv3.ko" and "nfsv4.ko".
I also had to move the nfs4_fs_type back to nfs.ko to ensure that `mount
-t nfs4` still works.
