Pull drm fixes from Dave Airlie:
"This is radeon and intel fixes, and is a small bit larger than I'm
guessing you'd like it to be.
- i915: fixes 32-bit highmem i915 blank screen, semaphore hang and
runtime pm fix
- radeon: gpuvm stability fix for hangs since 3.15, and hang/reboot
regression on TN/RL devices,
The only slightly controversial one is the change to use GB for the
vm_size, which I'm letting through as its a new interface we defined
in this merge window, and I'd prefer to have the released kernel have
the final interface rather than changing it later"

Enable ARMCLK down feature on all Exynos4 SoCs. The frequency of
ARMCLK will be reduced upon entering idle mode (WFI or WFE).
The feature behaves like very fast cpufreq ondemand governor. In idle
mode this reduces energy consumption on full frequency chosen by
cpufreq governor by approximately:
- Trats2: 6.5% (153 mA -> 143 mA)
- Trats: 33.0% (180 mA -> 120 mA)
- Gear1: 27.0% (180 mA -> 130 mA)
The patch uses simillar settings as Exynos5250 (clk-exynos5250.c),
except it disables clock up feature and on Exynos4412 ARMCLK down is
enabled for all 4 cores.
Tested on Trats board (Exynos4210), Trats2 board (Exynos4412) and
Samsung Gear 1 (Exynos4212).

The Power Management Controller (PMC) controls many of the power
management features present in the Atom SoC. This driver provides
a native power off function via PMC PCI IO port.
On some ACPI hardware-reduced platforms(e.g. ASUS-T100), ACPI sleep
registers are not valid so that (*pm_power_off)() is not hooked by
acpi_power_off(). The power off function in this driver is installed
only when pm_power_off is NULL.

Investigation shows, that f2fs_evict_inode, when called for
'meta_inode', uses invalidate_mapping_pages() for 'node_inode'.
But 'node_inode' is deleted before 'meta_inode' in f2fs_put_super via
iput().
It seems that in common usage scenario this use-after-free is benign,
because 'node_inode' remains partially valid data even after
kmem_cache_free().
But things may change if, while 'meta_inode' is evicted in one f2fs
filesystem, another (mounted) f2fs filesystem requests inode from cache,
and formely
'node_inode' of the first filesystem is returned."
Nids for both meta_inode and node_inode are reservation, so it's not necessary
for us to invalidate pages which will never be allocated.
To fix this issue, let's skipping needlessly invalidating pages for
{meta,node}_inode in f2fs_evict_inode.

The PERF_RECORD_FINISHED_ROUND synthetic record governs queue flushing
in reporting, so it needs to be stored for any kind of event.
The lack of such periodic flushing made the tools use more memory than
needed, as the reordering was being done only after processing all

Resolve missing-field-initializers warnings seen in W=2 kernel
builds by having macros generate more elaborated initializers.
That is enough to silence the warnings.

GICv3 introduces new system registers accessible with the full msr/mrs
syntax (e.g. mrs x0, Sop0_op1_CRm_CRn_op2). However, only recent
binutils understand the new syntax. This patch introduces msr_s/mrs_s
assembly macros which generate the equivalent instructions above and
converts the existing GICv3 code (both drivers/irqchip/ and
arch/arm64/kernel/).

devm_ioremap_resource()
The raminit register is shared register for both can0 and can1. Since commit:
32766ff net: can: Convert to use devm_ioremap_resource
devm_ioremap_resource() is used to map raminit register. When using both
interfaces the mapping for the can1 interface fails, leading to a non
functional can interface.

When TSO packet is transmitted additional BD w/o mapping is used

When the usb speed of the RTL8152 is not high speed, the USB_DEV_STAT[2:1]
should be equal to [0 1]. That is, the STAT_SPEED_FULL should be equal
to 2.
There is a easy way to check the usb speed by the speed field of the
struct usb_device. Use it to replace the original metheod.

John W. Linville says:
====================
pull request: wireless 2014-07-24
Please pull this batch of fixes intended for the 3.16 stream...
For the mac80211 fixes, Johannes says:
"I have two fixes: one for tracing that fixes a long-standing NULL
pointer dereference, and one for a mac80211 issue that causes iwlmvm to
send invalid frames during authentication/association."
and,
"One more fix - for a bug in the newly introduced code that obtains rate
control information for stations."
For the iwlwifi fixes, Emmanuel says:
"It includes a merge damage fix. This region has been changed in -next
and -fixes quite a few times and apparently, I failed to handle it
properly, so here the fix. Along with that I have a fix from Eliad
to properly handle overlapping BSS in AP mode."
On top of that, Felix provides and ath9k fix for Tx stalls that happen
after an aggregation session failure.
Please let me know if there are problems! There are some changes
here that will cause merge conflicts in -next. Once you merge this
I can pull it into wireless-next and resolve those issues.

net: phy: Prevent an MDIO bus from being unloaded while in use
Changes from v1:
* Dropped the unneeded module_put() on phy_attach_direct().
The motivation of this small series is to fix the current lack of relationship
between an ethernet driver and the MDIO bus behind the PHY device. In such
cases, we would find no visible link between the drivers:
$ lsmod
Module Size Used by Not tainted
mvmdio 2941 0
mvneta 22069 0
Which means nothing prevents the MDIO driver from being removed:
$ modprobe -r mvmdio
# Unable to handle kernel NULL pointer dereference at virtual address 00000060
pgd = c0004000
[00000060] *pgd=00000000
Internal error: Oops: 17 [#1] SMP ARM
Modules linked in: mvneta [last unloaded: mvmdio]
CPU: 0 PID: 22 Comm: kworker/0:1 Not tainted 3.16.0-rc5-01127-g62c0816-dirty #608
Workqueue: events_power_efficient phy_state_machine
task: df5ec840 ti: df67a000 task.ti: df67a000
PC is at phy_state_machine+0x1c/0x468
LR is at phy_state_machine+0x18/0x468
[snip]
This patchset fixes this problem by adding a pair of module_{get,put},
so the module reference count is increased when the PHY device is attached
and is decreased when the PHY is detached.
Tested with mvneta and mv643xx_eth drivers, which depend on the mvmdio
driver to handle MDIO. This series applies on both net and net-next branches.
