bridge: add brport flags to dflt bridge_getlink
To allow brport device to return current brport flags set on port. Add
returned flags to nested IFLA_PROTINFO netlink msg built in dflt getlink.

bridge: add API to notify bridge driver of learned FBD on offloaded device
When the swdev device learns a new mac/vlan on a port, it sends some async
notification to the driver and the driver installs an FDB in the device.
To give a holistic system view, the learned mac/vlan should be reflected
in the bridge's FBD table, so the user, using normal iproute2 cmds, can view
what is currently learned by the device. This API on the bridge driver gives
a way for the swdev driver to install an FBD entry in the bridge FBD table.
(And remove one).
This is equivalent to the device running these cmds:
bridge fdb [add|del] <mac> dev <dev> vid <vlan id> master
This patch needs some extra eyeballs for review, in paricular around the
locking and contexts.

MIPS: tlbex: Fix potential HTW race on TLBL/M/S handlers
There is a potential race when probing the TLB in TLBL/M/S exception
handlers for a matching entry. Between the time we hit a TLBL/S/M
exception and the time we get to execute the TLBP instruction, the
HTW may have replaced the TLB entry we are interested in hence the TLB
probe may fail. However, in the existing handlers, we never checked the
status of the TLBP (ie check the result in the C0/Index register). We
fix this by adding such a check when the core implements the HTW. If
we couldn't find a matching entry, we return back and try again.

ARM: 8226/1: cacheflush: get rid of restarting block
We cannot restart cacheflush safely if a process provides user-defined
signal handler and signal is pending. In this case -EINTR is returned
and it is expected that process re-invokes syscall. However, there are
a few problems with that:
* looks like nobody bothers checking return value from cacheflush
* but if it did, we don't provide the restart address for that, so the
process has to use the same range again
* ...and again, what might lead to looping forever
So, remove cacheflush restarting code and terminate cache flushing
as early as fatal signal is pending.

ARM: 8222/1: mvebu: enable strex backoff delay
Under extremely rare conditions, in an MPCore node consisting of at
least 3 CPUs, two CPUs trying to perform a STREX to data on the same
shared cache line can enter a livelock situation.
This patch enables the HW mechanism that overcomes the bug. This fixes
the incorrect setup of the STREX backoff delay bit due to a wrong
description in the specification.
Note that enabling the STREX backoff delay mechanism is done by
leaving the bit *cleared*, while the bit was currently being set by
the proc-v7.S code.

ARM: tegra: irq: fix buggy usage of irq_data irq field
The crazy gic_arch_extn thing that Tegra uses contains multiple
references to the irq field in struct irq_data, and uses this

But irq is the *virtual* irq number, something that has nothing
to do with the actual HW irq (stored in the hwirq field). And once
we put the stacked domain code in action, the whole thing explodes,
as these two values are *very* different:

This patch series add EEE support to the Broadcom GENET driver, first patch
basically adds register definitions for the hardware, the second patch does the
actual implementation and hooks the {get,set}_eee ethtool callbacks, the last
patch adds auto-negotiation restart capability.

Third set of IIO fixes for the 3.18 cycle.
Most of these are fairly standard little fixes, a bmc150 and bmg160 patch
is to make an ABI change to indicated a specific axis in an event rather
than the generic option in the original drivers. As both of these drivers
are new in this cycle it would be ideal to push this minor change through
even though it isn't strictly a fix. A couple of other 'fixes' change
defaults for some settings on these new drivers to more intuitive calues.
Looks like some useful feedback has been coming in for this driver
since it was applied.
* IIO_EVENT_CODE_EXTRACT_DIR bit mask was wrong and has been for a while
0xCF clearly doesn't give a contiguous bitmask.
* kxcjk-1013 range setting was failing to mask out the previous value
in the register and hence was 'enable only'.
* men_z188 device id table wasn't null terminated.
* bmg160 and bmc150 both failed to correctly handling an error in mode
setting.
* bmg160 and bmc150 both had a bug in setting the event direction in the
event spec (leads to an attribute name being incorrect)
* bmg160 defaulted to an open drain output for the interrupt - as a default
this obviously only works with some interrupt chips - hence change the
default to push-pull (note this is a new driver so we aren't going to
cause any regressions with this change).
* bmc150 had an unintuitive default for the rate of change (motion detector)
so change it to 0 (new driver so change of default won't cause any
regressions).

standardize TIPC SKB queue operations
Now the following SKB queues are created and maintained within internal
TIPC stack:
- link transmission queue
- link deferred queue
- link receive queue
- socket outgoing packet chain
- name table outgoing packet chain
In order to manage above queues, TIPC stack declares a sk_buff pointer
for each queue to record its head, and directly modifies "prev" and
"next" SKB pointers of SKB structure when inserting or deleting a SKB
to or from the queue. As these operations are pretty complex, they
easily involve fatal mistakes. If these sk_buff pointers are replaced
with sk_buff_head instances as queue heads and corresponding generic
SKB list APIs are used to manage them, the entire TIPC code would
become quite clean and readable. But before make the change, we need
to clean up below redundant functionalities:
- remove node subscribe infrastructure
- remove protocol message queue
- remove retransmission queue
- clean up process of pushing packets in link layer

Under the current code, if any of these flags are set, the 32-bit

85c8555ff0 ("KVM: check for !is_zero_pfn() in

The problem being addressed by the patch above was that some ARM code
based the memory mapping attributes of a pfn on the return value of
kvm_is_mmio_pfn(), whose name indeed suggests that such pfns should
be mapped as device memory.
However, kvm_is_mmio_pfn() doesn't do quite what it says on the tin,
and the existing non-ARM users were already using it in a way which
suggests that its name should probably have been 'kvm_is_reserved_pfn'

it etc. This means that returning false for the zero page is a mistake

When running on a system with a GICv3, we currenly don't allow the guest

clearing the ICC_SRE_EL2.Enable, which causes all guest accesses to
ICC_SRE_EL1 to trap to EL2 and causes all guest accesses to other ICC_
registers to cause an undefined exception in the guest.
However, we currently don't handle the trap of guest accesses to
ICC_SRE_EL1 and will spill out a warning. The trap just needs to handle
the access as RAZ/WI, and a guest that tries to prod this register and
set ICC_SRE_EL1.SRE=1, must read back the value (which Linux already

aio: fix uncorrent dirty pages accouting when truncating AIO ring buffer
Linus Torvalds [Wed, 26 Nov 2014 02:43:21 +0000 (18:43 -0800)]
Merge branch 'merge' of git://git./linux/kernel/git/benh/powerpc
Pull powerpc fixes from Ben Herrenschmidt:
"This series fix a nasty issue with radeon adapters on powerpc servers,
it's all CC'ed stable and has the relevant maintainers ack's/reviews.
Basically, some (radeon) adapters have issues with MSI addresses above
1T (only support 40-bits). We had powerpc specific quirk but it only
listed a specific revision of an adapter that we shipped with our
machines and didn't properly handle the audio function which some
distros enable nowadays.
So we made the quirk generic and fixed both the graphic and audio
drivers properly to use it.
Without that, ppc64 server machines will crash at boot with a radeon
adapter.
Note: This has been brewing for a while, it just needed a last respin
which got delayed due to us moving ozlabs to a new location in town
and other such things taking priority"
