ALSA: hda - Fix possible race on regmap bypass flip
HD-audio driver uses regmap cache bypass feature for reading a raw
value without the cache. But this is racy since both the cached and
the uncached reads may occur concurrently. The former is done via the
normal control API access while the latter comes from the proc file
read.
Even though the regmap itself has the protection against the
concurrent accesses, the flag set/reset is done without the
protection, so it may lead to inconsistent state of bypass flag that
doesn't match with the current read and occasionally result in a
kernel WARNING like:
WARNING: CPU: 3 PID: 2731 at drivers/base/regmap/regcache.c:499 regcache_cache_only+0x78/0x93
One way to work around such a problem is to wrap with a mutex. But in
this case, the solution is simpler: for the uncached read, we just
skip the regmap and directly calls its accessor. The verb execution
there is protected by itself, so basically it's safe to call
individually.

ALSA: hda - Keep powering up ADCs on Cirrus codecs
Although one weird behavior about the input path (inconsistent D0/D3
switch) on Cirrus CS420x codecs was fixed in the previous commit,
there is still an issue on some Mac machines: the capture stream
stalls when switching the ADCs on the fly. More badly, this keeps
stuck until the next reboot.
The dynamic ADC switching is already a bit fragile and assuming
optimistically that the chip accepts the frequent power changes. On
Cirrus codecs, this doesn't seem applicable.
As a quick workaround, we pin down the ADCs to keep up in D0 when
spec->dyn_adc_switch is set. In this way, the ADCs are kept up only
for the system that were confirmed to be broken.

ALSA: hda - Don't trust the reported actual power state
We've got a regression report that the recording on Mac with a cirrus
codec doesn't work any longer. This turned out to be the missing
power up to D0 by power_save_node enablement.
After analyzing the traces, we found out that the culprit is that the
codec advertises the "actual" power state of a few nodes to be D0
while the "target" power state is D3. This inconsistency is usually
OK, as it implies the power transition. But in the case of cirrus
codec, this seems to be stuck to D3 while it's not actually D0.
This patch addresses the issue by checking the power state difference
more strictly. It sends the power-state change verb unless both the
target and the actual power states show the given value.
We may introduce yet another flag indicating the possible broken
hardware power state, but it's anyway safer to set the proper power
state even in a transition (at least it's harmless as long as the
target state is same). So this simpler change was applied now.

The commit [

The fix is to update pin_eld->monitor_present as well before calling
update_eld().

ALSA: hda - Bind with i915 only when Intel graphics is present
On Skylake and onwards, the HD-audio controller driver needs to bind
with i915 for having the control of power well audio domain before
actually probing the codec. This leads to the load of i915 driver
from the audio driver side. But, there are systems that have no Intel
graphics but Nvidia or AMD GPU, although they still use HD-audio bus
for the onboard audio codecs. On these, loading the i915 driver is
nothing but a useless memory and CPU consumption.
A simple way to avoid it is just to look for the Intel graphics PCI
entry beforehand, and try to bind with i915 only when such an entry is
found. Currently, it assumes the PCI display class. If another class
appears, this needs to be extended (although it's very unlikely).

Make CONFIG_FHANDLE default y
Newer Fedora and OpenSUSE didn't boot with my standard configuration.
It took me some time to figure out why, in fact I had to write a script
to try different config options systematically.
The problem is that something (systemd) in dracut depends on
CONFIG_FHANDLE, which adds open by file handle syscalls.
While it is set in defconfigs it is very easy to miss when updating
older configs because it is not default y.
Make it default y and also depend on EXPERT, as dracut use is likely
widespread.

bb29902a7515 ("oom, oom_reaper: protect oom_reaper_list using

the oom reaper by checking tsk->oom_reaper_list != NULL. This check is

mm/rmap: batched invalidations should use existing api

stmmac: fix MDIO settings
Initially the phy_bus_name was added to manipulate the
driver name but it was recently just used to manage the
fixed-link and then to take some decision at run-time.
So the patch uses the is_pseudo_fixed_link and removes
the phy_bus_name variable not necessary anymore.
The driver can manage the mdio registration by using phy-handle,
dwmac-mdio and own parameter e.g. snps,phy-addr.
This patch takes care about all these possible configurations
and fixes the mdio registration in case of there is a real
transceiver or a switch (that needs to be managed by using
fixed-link).

Same can be triggered with PROVE_RCU (+ PROVE_RCU_REPEATEDLY) enabled
from tun_attach_filter() when user space calls ioctl(tun_fd, TUN{ATTACH,
DETACH}FILTER, ...) for adding/removing a BPF filter on tap devices.
Since the fix in
f91ff5b9ff52 ("net: sk_{detach|attach}_filter() rcu
fixes") sk_attach_filter()/sk_detach_filter() now dereferences the
filter with rcu_dereference_protected(), checking whether socket lock
is held in control path.
Since its introduction in
994051625981 ("tun: socket filter support"),
tap filters are managed under RTNL lock from __tun_chr_ioctl(). Thus the
sock_owned_by_user(sk) doesn't apply in this specific case and therefore
triggers the false positive.
Extend the BPF API with __sk_attach_filter()/__sk_detach_filter() pair
that is used by tap filters and pass in lockdep_rtnl_is_held() for the
rcu_dereference_protected() checks instead.

ALSA: timer: Use mod_timer() for rearming the system timer
ALSA system timer backend stops the timer via del_timer() without sync
and leaves del_timer_sync() at the close instead. This is because of
the restriction by the design of ALSA timer: namely, the stop callback
may be called from the timer handler, and calling the sync shall lead
to a hangup. However, this also triggers a kernel BUG() when the
timer is rearmed immediately after stopping without sync:
kernel BUG at kernel/time/timer.c:966!
Call Trace:

It's the place where add_timer() checks the pending timer. It's clear
that this may happen after the immediate restart without sync in our
cases.
So, the workaround here is just to use mod_timer() instead of
add_timer(). This looks like a band-aid fix, but it's a right move,
as snd_timer_interrupt() takes care of the continuous rearm of timer.

drm/dp: move hw_mutex up the call stack
1) don't let other threads trying to bang on aux channel interrupt the
defer timeout/logic
2) don't let other threads interrupt the i2c over aux logic
Technically, according to people who actually have the DP spec, this
should not be required. In practice, it makes some troublesome Dell
monitor (and perhaps others) work, so probably a case of "It's compliant
if it works with windows" on the hw vendor's part..

Intel Wired LAN Driver Updates 2016-03-29
This series contains fixes to ixgbe and ixgbevf.
Tushar fixes an issue which was introduced with an earlier commit, where
hardware register RAR0 default MAC address does not get set properly.
Alex fixes two issues, first being the VXLAN port number should be stored
in network order instead of in host order. The second fix corrects the ATR
code to handle IPv6 extension headers. The issue was ATR code was assuming
that it would be able to use tcp_hdr for every TCP frame that came through,
but that is not the case, which resulted in bad filters being setup.
Mark fixes a use of usleep_range() to udelay() in the case where a lock
is being held.
Stefan fixes the offline self tests where ndo_stop() should be used instead
of ndo_close(), which causes IFF_UP to be cleared and interface routes get
removed.
Emil fixes the error case where we need to return an error when a MAC
address change is rejected by the PF. This helps prevent the user from
modifying the MAC address when the operation is not permitted.
Sridhar provides three fixes for ixgbe, all dealing with traffic class

nios2: Replace fdt_translate_address with of_flat_dt_translate_address
nios2 builds fail with the following build error.
arch/nios2/kernel/prom.c: In function 'early_init_dt_scan_serial':
arch/nios2/kernel/prom.c:100:2: error:

Commit
c90fe9c0394b ("of: earlycon: Move address translation to
of_setup_earlycon()") replaced fdt_translate_address() with
of_flat_dt_translate_address() but missed updating the nios2 code.

bpf: make padding in bpf_tunnel_key explicit
Make the 2 byte padding in struct bpf_tunnel_key between tunnel_ttl
and tunnel_label members explicit. No issue has been observed, and
gcc/llvm does padding for the old struct already, where tunnel_label
was not yet present, so the current code works, but since it's part
of uapi, make sure we don't introduce holes in structs.
Therefore, add tunnel_ext that we can use generically in future
(f.e. to flag OAM messages for backends, etc). Also add the offset
to the compat tests to be sure should some compilers not padd the
tail of the old version of bpf_tunnel_key.

bnxt_en: Fix ethtool -a reporting.
To report flow control tx/rx settings accurately regardless of autoneg
setting, we should use link_info->req_flow_ctrl. Before this patch,
the reported settings were only correct when autoneg was on.
