Pull spi fixes from Mark Brown:
"There's a couple of driver fixes here, plus one core fix for the DMA
mapping which wasn't doing the right thing for vmalloc()ed addresses
that hadn't been through kmap(). It's fairly rare to use vmalloc()
with SPI and it's a subset of those users who might fail so it's

====================
pull request: wireless 2014-11-26
Please pull this little batch of fixes intended for the 3.18 stream...
For the iwlwifi one, Emmanuel says:
"Not all the firmware know how to handle the HOT_SPOT_CMD.
Make sure that the firmware will know this command before
sending it. This avoids a firmware crash."
Along with that, Larry sends a pair of rtlwifi fixes to address some
discrepancies from moving drivers out of staging. Larry says:
"These two patches are needed to fix a regression introduced when
driver rtl8821ae was moved from staging to the regular wireless tree."
Please let me know if there are problems!

Some VF drivers use the upper byte of "param1" (the qp count field)
in mlx4_qp_reserve_range() to pass flags which are used to optimize
the range allocation.
Under the current code, if any of these flags are set, the 32-bit
count field yields a count greater than 2^24, which is out of range,
and this VF fails.
As these flags represent a "best-effort" allocation hint anyway, they may
safely be ignored. Therefore, the PF driver may simply mask out the bits.

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"

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.

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.

Some radeon ASICs don't support all 64 address bits of MSIs despite
advertising support for 64-bit MSIs in their configuration space.
This breaks on systems such as IBM POWER7/8, where 64-bit MSIs can
be assigned with some of the high address bits set.
This makes use of the newly introduced "no_64bit_msi" flag in structure
pci_dev to allow the MSI allocation code to fallback to 32-bit MSIs
on those adapters.

This can be set by quirks/drivers to be used by the architecture code
that assigns the MSI addresses.

The issue is that test_and_set_bit() done on adapter->state is being
performed *after* the netdevice has been freed via free_netdev().
When netdev is being allocated on initialization time, it allocates
a private area, here struct ixgbe_adapter, that resides after the
net_device structure. In ixgbe_probe(), the device init routine,
we set up the adapter after alloc_etherdev_mq() on the private area
and add a reference for the pci_dev as well via pci_set_drvdata().
Both in the error path of ixgbe_probe(), but also on module unload
when ixgbe_remove() is being called, commit 41c62843eb6a ("ixgbe:
Fix rcu warnings induced by LER") accesses adapter after free_netdev().
The patch stores the result in a bool and thus fixes above oops on my
side.

IXGBE adapter seems to require that VLAN filtering be enabled if
VMDQ or SRIOV are enabled. When those functions are disabled,
VLAN filtering may be disabled in promiscuous mode.
Prior to commit a9b8943ee129 ("ixgbe: remove vlan_filter_disable
and enable functions")
The logic was correct. However, after the commit the logic
got reversed and VLAN filtered in now turned on when VMDQ/SRIOV
is disabled.
This patch changes the condition to enable hw vlan filtered
when VMDQ or SRIOV is enabled.

Pull ACPI power management fix from Rafael Wysocki:
"This is just a one-liner fixing a regression introduced in 3.13 that
broke system suspend on some Chromebooks.
On those machines there are ACPI device objects for some I2C devices
that can wake up the system from sleep states, but that is done via a
platform-specific mechanism and the ACPI objects don't contain any
wakeup-related information. When we started to use ACPI power
management with those devices (which happened during the 3.13 cycle),
their configuration confused the ACPI PM layer that returned error
codes from suspend callbacks for them causing system suspend to fail.
However, the ACPI PM layer can safely ignore the wakeup setting from a
device driver if the ACPI object corresponding to the device in
question doesn't contain wakeup information in which case the driver
itself is responsible for setting up the device for system wakeup"

====================
pull request: wireless 2014-11-20
Please full this little batch of fixes intended for the 3.18 stream!
For the mac80211 patch, Johannes says:
"Here's another last minute fix, for minstrel HT crashing
depending on the value of some uninitialised stack."
On top of that...
Ben Greear fixes an ath9k regression in which a BSSID mask is
miscalculated.
Dmitry Torokhov corrects an error handling routing in brcmfmac which
was checking an unsigned variable for a negative value.
Johannes Berg avoids a build problem in brcmfmac for arches where
linux/unaligned/access_ok.h and asm/unaligned.h conflict.
Mathy Vanhoef addresses another brcmfmac issue so as to eliminate a
use-after-free of the URB transfer buffer if a timeout occurs.
Please let me know if there are problems!

pptp_getname() only partially initializes the stack variable sa,
particularly only fills the pptp part of the sa_addr union. The code
thereby discloses 16 bytes of kernel stack memory via getsockname().
Fix this by memset(0)'ing the union before.

This is a specific implementation, <asm/unaligned.h> is the
multiplexer that has the arch-specific knowledge of which
of the implementations needs to be used, so include that.
This issue was revealed by kbuild testing
when <asm/unaligned.h> was added in <linux/ieee80211.h>
resulting in redefinition of get_unaligned_be16 (and
probably others).

Just use the acpi interface. That's what windows uses on this

on these generation parts.
You can still force the native backlight interface by setting

As reported by Dmitry, on some Chromebooks there are devices with
corresponding ACPI objects and with unusual system wakeup
configuration. Namely, they technically are wakeup-capable, but the
wakeup is handled via a platform-specific out-of-band mechanism and
the ACPI PM layer has no information on the wakeup capability. As
a result, device_may_wakeup(dev) called from acpi_dev_suspend_late()
returns 'true' for those devices, but the wakeup.flags.valid flag is
unset for the corresponding ACPI device objects, so acpi_device_wakeup()
reproducibly fails for them causing acpi_dev_suspend_late() to return
an error code. The entire system suspend is then aborted and the
machines in question cannot suspend at all.
Address the problem by ignoring the device_may_wakeup(dev) return
value in acpi_dev_suspend_late() if the ACPI companion of the device
being handled has wakeup.flags.valid unset (in which case it is clear
that the wakeup is supposed to be handled by other means).
This fixes a regression introduced by commit a76e9bd89ae7 (i2c:
attach/detach I2C client device to the ACPI power domain) as the
affected systems could suspend and resume successfully before that
commit.

g762_remove() needs to first call hwmon_device_unregister() and then
g762_of_clock_disable(). For that reason, it is not possible to
convert it to devm_hwmon_device_register_with_groups() and the
the non device managed version must be used.
This is correctly stated in commit message for 398e16db6262 ("hwmon:
(g762) Convert to hwmon_device_register_with_groups") but the
associated changes do in fact introduce a call to the device managed
version of the function.
This patch fixes that typo by switching to the non devm_ version.
