OPPs are created statically (from DT) or dynamically. Currently we don't free
OPPs that are created statically, when the module unloads. And so if the module

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

This patch enables the HW mechanism that overcomes the bug. This fixes

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
to directly poke hardware register.
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:

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).

be mapped as device memory.
However, kvm_is_mmio_pfn() doesn't do quite what it says on the tin,

arm64: KVM: Handle traps of ICC_SRE_EL1 as RAZ/WI
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
does) to see if it succeeded, and will thus observe that ICC_SRE_EL1.SRE
was not set.

In the past that was perfectly fine since the vdd off work didn't do

run during system resume before i915 has resumed, nothing would happen.
However since pps_lock() will now grab the power domain references before

tg3: fix ring init when there are more TX than RX channels
If TX channels are set to 4 and RX channels are set to less than 4,
using ethtool -L, the driver will try to initialize more RX channels
than it has allocated, causing an oops.
This fix only initializes the RX ring if it has been allocated.

tcp: fix possible NULL dereference in tcp_vX_send_reset()
After commit ca777eff51f7 ("tcp: remove dst refcount false sharing for
prequeue mode") we have to relax check against skb dst in
tcp_v[46]_send_reset() if prequeue dropped the dst.
If a socket is provided, a full lookup was done to find this socket,
so the dst test can be skipped.

If the conntrack clashes with an existing one, it is left out of
the unconfirmed list, thus, crashing when dropping the packet and
releasing the conntrack since golden rule is that conntracks are
always placed in any of the existing lists for traceability reasons.

Merge branch 'ipv6_vxlan_outer_udp_csum'
Alexander Duyck says:
====================
Fix outer UDP checksums for IPv6 VXLAN tunnels
In testing against an older kernel I found a couple issues in the IPv6
VXLAN tunnel checksum logic for the outer UDP checksum.
First the default transitioned from using an outer checksum to not using
one. Second, sometime after that the checksum inputs were changed
resulting the checksum not being correct if it were computed.
These two issues prevented a ping from the newer kernel to the older one.
With these two changes applied I verified I was able to send traffic over
the VXLAN tunnel to a link partner on an older kernel.
The boolean flip fix can be submitted for 3.17 stable as well since the
patch that introduced the issue was included in that kernel.

vxlan: Fix boolean flip in VXLAN_F_UDP_ZERO_CSUM6_[TX|RX]
In "vxlan: Call udp_sock_create" there was a logic error that resulted in
the default for IPv6 VXLAN tunnels going from using checksums to not using
checksums. Since there is currently no support in iproute2 for setting
these values it means that a kernel after the change cannot talk over a IPv6
VXLAN tunnel to a kernel prior the change.

ip6_udp_tunnel: Fix checksum calculation
The UDP checksum calculation for VXLAN tunnels is currently using the
socket addresses instead of the actual packet source and destination
addresses. As a result the checksum calculated is incorrect in some
cases.
Also uh->check was being set twice, first it was set to 0, and then it is
set again in udp6_set_csum. This change removes the redundant assignment
to 0.

The xpad wireless endpoint is not a bulk endpoint on my devices, but
rather an interrupt one, so the USB core complains when it is submitted.
I'm guessing that the author really did mean that this should be an
interrupt urb, but as there are a zillion different xpad devices out
there, let's cover out bases and handle both bulk and interrupt
endpoints just as easily.
