There is no need to call a heavyweight phy_start_aneg() for phy
auto-negotiation by ethtool, the phy is already initialized and
link auto-negotiation is started by calling phy_start() from
sh_eth_phy_start() when a network device is opened.

The change fixes sleep in atomic context bug, which is encountered
every time when link settings are changed by ethtool.
Since commit 35b5f6b1a82b ("PHYLIB: Locking fixes for PHY I/O
potentially sleeping") phy_start_aneg() function utilizes a mutex
to serialize changes to phy state, however that helper function is
called in atomic context under a grabbed spinlock, because
phy_start_aneg() is called by phy_ethtool_ksettings_set() and by
replaced phy_ethtool_sset() helpers from phylib.
Now duplex mode setting is enforced in sh_eth_adjust_link() only,
also now RX/TX is disabled when link is put down or modifications
to E-MAC registers ECMR and GECMR are expected for both cases of
checked and ignored link status pin state from E-MAC interrupt handler.
For reference the change is a partial rework of commit 1e1b812bbe10
("sh_eth: fix handling of no LINK signal").

These are two simple fixes, yet the first one is quite important as it
solves boots hangs we've been having when FDIV2 gets disabled. This did
not show up before because this particular clock is heavily used and

as ethernet or emmc) probe.

- fix racalculation error in the clk_audio_divider

On some systems, we come out of the bootloader with some
gates set with the clock "enabled" but the reset also
asserted.
Since 8a53fc511c5e "clk: aspeed: Prevent reset if clock is enabled"
we check that enabled bit in aspeed_clk_enabled(), and do
nothing if already set.
This breaks when the above scenario occurs, as the clock
is enabled, but the reset still needs to be lifted.
This patch fixes it by also checking the reset bit (if any)
and treating a gate in "reset" as being disabled.

buffer in VFS read/write handlers can lead to both kernel memory corruption
(via kernel_read()/kernel_write(), which can e.g. be triggered via

The current implementation of cfg80211_rx_control_port assumed that the
caller could provide a contiguous region of memory for the control port
frame to be sent up to userspace. Unfortunately, many drivers produce
non-linear skbs, especially for data frames. This resulted in userspace
getting notified of control port frames with correct metadata (from
address, port, etc) yet garbage / nonsense contents, resulting in bad
handshakes, disconnections, etc.
mac80211 linearizes skbs containing management frames. But it didn't
seem worthwhile to do this for control port frames. Thus the signature
of cfg80211_rx_control_port was changed to take the skb directly.
nl80211 then takes care of obtaining control port frame data directly
from the (linear | non-linear) skb.
The caller is still responsible for freeing the skb,
cfg80211_rx_control_port does not take ownership of it.

The low and high values of the net.ipv4.ping_group_range sysctl were
being silently forced to the default disabled state when a write to the
sysctl contained GIDs that didn't map to the associated user namespace.
Confusingly, the sysctl's write operation would return success and then
a subsequent read of the sysctl would indicate that the low and high
values are the overflowgid.
This patch changes the behavior by clearly returning an error when the
sysctl write operation receives a GID range that doesn't map to the
associated user namespace. In such a situation, the previous value of
the sysctl is preserved and that range will be returned in a subsequent
read of the sysctl.

Pull drm fixes from Dave Airlie:
"This is the drm fixes for rc4.
It's a bit larger than I'd like but the exynos cleanups are pretty
mechanical, and I'd rather have them in sooner rather than later so we
can avoid too much conflicts around them. The non-mechanincal exynos
changes are mostly fixes for new feature recently introduced.
Apart from the exynos updates, we have:
i915:
- GVT and GGTT mapping fixes
amdgpu:
- fix HDMI2.0 4K@60 Hz regression
- Hotplug fixes for dual-GPU laptops to make power management better
- misc vega12 bios fixes, a race fix and some typos.
sii8620 bridge:
- small fixes around mode setting
core:
- use kvzalloc to allocate blob property memory"

The notification of scrub completion happens within the scrub workqueue.
That can clearly race someone running scrub_show() and work_busy()
before the workqueue has a chance to flush the recently completed work.
Add a flag to reliably indicate the idle vs busy state. Without this
change applications using poll(2) to wait for scrub-completion may
falsely wakeup and read ARS as being busy even though the thread is
going idle and then hang indefinitely.

Setting up macvlan/macvtap networks over atlantic NIC results
in no traffic over these networks because ndo_set_rx_mode did
not listed UC MACs as registered in unicast filter.
Here we fix that taking into account maximum number of UC
filters supported by hardware. If more than MAX addresses were
registered, we just enable promisc and/or allmulti to pass
the traffic in.
We also remove MULTICAST_ADDRESS_MAX constant from aq_cfg since
thats not a configurable parameter at all.

schedule_timeout_* takes a timeout in jiffies but the code currently is
passing in a constant which makes this timeout HZ dependent. So define
a constant with (hopefully) meaningful name and pass it through
msecs_to_jiffies() to fix the HZ dependency.

git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-fixes
Fixups
- Fix several problems to IPPv2 merged to mainline recentely.
. An align problem of width size that IPP driver incorrectly
calculated the real buffer size.
. Horizontal and vertical flip problem.
. Per-plane global alpha for XRGB modes.
. Incorrect variant of the YUV modes.
- Fix plane overlapping problem.
. The stange order of overlapping planes on XRGB modes
by setting global alpha value to maximum value.
Cleanup
- Rename a enum type, drm_ipp_size_id, to one specific to Exynos,
drm_exynos_ipp_limit_type.
- Replace {un/reference} with {put,get} functions.
. it replaces several reference/unreference functions with Linux
kernel nameing standard.
