With gcc 8 we get new set of snprintf() warnings that breaks the
compilation, one example:
tests/mem.c: In function ‘check’:
tests/mem.c:19:48: error: ‘%s’ directive output may be truncated writing \
up to 99 bytes into a region of size 89 [-Werror=format-truncation=]
snprintf(failure, sizeof failure, "unexpected %s", out);
The gcc docs says:
To avoid the warning either use a bigger buffer or handle the
function's return value which indicates whether or not its output
has been truncated.
Given that all these warnings are harmless, because the code either
properly fails due to uncomplete file path or we don't care for
truncated output at all, I'm changing all those snprintf() calls to
scnprintf(), which actually 'checks' for the snprint return value so the
gcc stays silent.

For DSI cmd-mode and writeback, we need to write the CTL's START
register to kick things off, but we only want to do that once both
the encoder and the crtc have a chance to write their corresponding
flush bits. The difficulty is that when there is a full modeset
(ie. encoder state has changed) we want to defer the start until
encoder->enable(). But if only plane's have changed, we want to do
this from crtc->commit().
The start_mask was a previous attempt to handle this, but it didn't
really do the right thing since atomic conversion.
Instead track in the crtc state that the start should be deferred,
set to try from encoder's (or in future writeback's) atomic_check().
This way the state is part of the atomic state, and rollback can
work properly if an atomic test fails.

Interrupt commands causes the CP to trigger an interrupt as the command
is processed, regardless of the GPU being done processing previous
commands. This is seen by the interrupt being delivered before the
fence is written on 8974 and is likely the cause of the additional
CP_WAIT_FOR_IDLE workaround found for a306, which would cause the CP to
wait for the GPU to go idle before triggering the interrupt.
Instead we can set the (undocumented) BIT(31) of the CACHE_FLUSH_TS
which will cause a special CACHE_FLUSH_TS interrupt to be triggered from
the GPU as the write event is processed.
Add CACHE_FLUSH_TS to the IRQ masks of A3xx and A4xx and remove the
workaround for A306.

Our shadow context content is from guest but with masked control reg like
CTX_CONTEXT_CONTROL, we need to make sure all settings from guest would be set
when this context is on hw, this trys to force mask enable bits for all to
ensure every bits setting would be effective on hw.
One regression found related to once inhibit bit is set, gpu engine are working
on inhibit state until MI_LOAD_REG_IMM command or context image clear inhibit
bit with mask bit set to 1, and val bit set to 0. In gvt-g currently workload
has the highest priority, so gvt-g workload could trigger preempt context
easily, preempt context set inhibit bit, then gvt-g workload is scheduled in,
but gvt-g workload shadow context image usually doesn't set inhibit mask bit,
so gpu is still in inhibit state when gvt workload is running. This caused gpu
hang.

memory bitmask, and warns if no mask is set or even allocated.
Set z->dev.dma_coherent_mask on Zorro bus scan, and make z->dev.dma_mask

The PMU watchdog will power down the system if the kernel is slow
to start up, e.g. due to unpacking a large initrd. The powerpc
version of this driver (via-pmu.c) has a solution for the same
problem. It uses this call sequence:
setup_arch
find_via_pmu
init_pmu
...
arch_initcall
via_pmu_start
Bring via-pmu68k.c into line with via-pmu.c to fix this issue.

Revert commit c68f0676ef7d ("ACPI / battery: Add quirk for Asus
GL502VSK and UX305LA") and commit 4446823e2573 ("ACPI / battery: Add
quirk for Asus UX360UA and UX410UAK").
On many many Asus products, the battery is sometimes reported as
charging or discharging even when it is full and you are on AC power.
This change quirked the kernel to avoid advertising the discharging
state when this happens on 4 laptop models, under the belief that
this was incorrect information. I presume it originates from user
reports who are confused that their battery status icon says that it
is discharging.
However, the reported information is indeed correct, and the quirk
approach taken is inadequate and more thought is needed first.
Specifically:
1. It only quirks discharging state, not charging
2. There are so many different Asus products and DMI naming variants
within those product families that behave this way; Linux could
grow to quirk hundreds of products and still not even be close at
"winning" this battle.
3. Asus previously clarified that this behaviour is intentional. The
platform will periodically do a partial discharge/charge cycle
when the battery is full, because this is one way to extend the
lifetime of the battery (leaving a battery at 100% charge and
unused will decrease its usable capacity over time).
My understanding is that any decent consumer product will have
this behaviour, but it appears that Asus is different in that
they expose this info through ACPI.
However, the behaviour seems correct. The ACPI spec does not
suggest in that the platform should hide the truth. It lets you
report that the battery is full of charge, and discharging, and
with external power connected; and Asus does this.
4. In terms of not confusing the user, this seems like something that
could/should be handled by userspace, which can also detect these
same (accurate) conditions in the general case.
Revert this quirk before it gets included in a release, while we look
for better approaches.

Since commit 846c7dfc1193 ("drm/atomic: Try to preserve the crtc enabled
state in drm_atomic_remove_fb, v2."), removing the last framebuffer will
no longer disable the corresponding pipeline, which causes the KMS core
to complain about leaked connectors on driver unbind.
Fix this by calling drm_atomic_helper_shutdown() on driver unbind, which
will cause all display pipelines to be shut down and therefore drop the

When immediate quiet bit is set in CSA, the entire channel is blocked
by the firmware. It is expected that all the MACs will evacuate the
channel and the phy will be eventually either moved or removed.
Currently, the phy context is just unreferenced and thus, the quiet
bit is kept set and it will be impossible to TX on this phy, if we
will need to reuse it in the future. This can be seen when doing a
channel switch with mode=1 (quiet) twice from channel X to Y and then
back to channel X.
Fix that, by moving the phy context to a default channel when not
referenced anymore.

When a queue is reserved for aggregation, the queue id is assigned
to the tid_data. This is fine since iwl_mvm_sta_tx_agg_oper()
takes care of allocating the queue before actual tx starts.
When the reservation is cancelled (e.g. when the AP declined the
aggregation request) the tid_data is not cleared. As a result,
following tx for this tid was trying to use an unallocated queue.
Fix this by setting the txq_id for the tid to invalid when unreserving
the queue.

After switching to a new channel, driver schedules session protection
time event in order to hear the beacon on the new channel.
The duration of the protection is two beacon intervals.
However, since we start to switch slightly before beacon with count 1, in
case we don't hear (or AP doesn't transmit) the very first beacon on the
new channel the protection ends without hearing any beacon at all.
At this stage the switch is not complete, the queues are closed and the
interface doesn't have quota yet or TBTT events. As the result, we are
stuck forever waiting for iwl_mvm_post_channel_switch() to be called.
Fix this by increasing the protection time to be 3 beacon intervals and
in addition drop the connection if the time event ends before we got any
beacon.

In vti6_link_config(), if MTU is already given on link creation
or change, validate and use it instead of recomputing it. To do
that, we need to propagate the knowledge that MTU was set by
userspace all the way down to vti6_link_config().
To keep this simple, vti6_dev_init() sets the new 'keep_mtu'
argument of vti6_link_config() to true: on initialization, we
don't have convenient access to netlink attributes there, but we
will anyway check whether dev->mtu is set in vti6_link_config().
If it's non-zero, it was set to the value of the IFLA_MTU
attribute during creation. Otherwise, determine a reasonable
value.

If a lower device is found, we don't need to subtract
LL_MAX_HEADER to calculate our MTU: just use its MTU, the link
layer headers are already taken into account by it.
If the lower device is not found, start from ETH_DATA_LEN
instead, and only in this case subtract a worst-case
LL_MAX_HEADER.
We then need to subtract our additional IPv6 header from the
calculation.
While at it, note that vti6 doesn't have a hardware header, so
it doesn't need to set dev->hard_header_len. And as
vti6_link_config() now always sets the MTU, there's no need to
set a default value in vti6_dev_setup().
This makes the behaviour consistent with IPv4 vti, after
commit a32452366b72 ("vti4: Don't count header length twice."),
which was accidentally reverted by merge commit f895f0cfbb77
("Merge branch 'master' of
git://git.kernel.org/pub/scm/linux/kernel/git/klassert/ipsec").
While commit 53c81e95df17 ("ip6_vti: adjust vti mtu according to
mtu of lower device") improved on the original situation, this
was still not ideal. As reported in that commit message itself,
if we start from an underlying veth MTU of 9000, we end up with
an MTU of 8832, that is, 9000 - LL_MAX_HEADER - sizeof(ipv6hdr).
This should simply be 8880, or 9000 - sizeof(ipv6hdr) instead:
we found the lower device (veth) and we know we don't have any
additional link layer header, so there's no need to subtract an
hypothetical worst-case number.

This re-introduces the effect of commit a32452366b72 ("vti4:
Don't count header length twice.") which was accidentally
reverted by merge commit f895f0cfbb77 ("Merge branch 'master' of
git://git.kernel.org/pub/scm/linux/kernel/git/klassert/ipsec").
The commit message from Steffen Klassert said:
We currently count the size of LL_MAX_HEADER and struct iphdr
twice for vti4 devices, this leads to a wrong device mtu.
The size of LL_MAX_HEADER and struct iphdr is already counted in
ip_tunnel_bind_dev(), so don't do it again in vti_tunnel_init().
And this is still the case now: ip_tunnel_bind_dev() already
accounts for the header length of the link layer (not
necessarily LL_MAX_HEADER, if the output device is found), plus
one IP header.
For example, with a vti device on top of veth, with MTU of 1500,
the existing implementation would set the initial vti MTU to
1332, accounting once for LL_MAX_HEADER (128, included in
hard_header_len by vti) and twice for the same IP header (once
from hard_header_len, once from ip_tunnel_bind_dev()).
It should instead be 1480, because ip_tunnel_bind_dev() is able
to figure out that the output device is veth, so no additional
link layer header is attached, and will properly count one
single IP header.
The existing issue had the side effect of avoiding PMTUD for
most xfrm policies, by arbitrarily lowering the initial MTU.
However, the only way to get a consistent PMTU value is to let
the xfrm PMTU discovery do its course, and commit d6af1a31cc72
("vti: Add pmtu handling to vti_xmit.") now takes care of local
delivery cases where the application ignores local socket

The PDPs of a shadow page will only be valid after a vGPU mm is pinned.
So the PDPs in the shadow context should be updated then.

As different OSes might handling GVT PPGTT creation/destroy notification
differently during a vGPU reset. A better approach is invalidating all
vGPU PPGTT mm objects during vGPU reset.

Pull x86/pti updates from Thomas Gleixner:
"Another set of melted spectrum updates:
- Iron out the last late microcode loading issues by actually
checking whether new microcode is present and preventing the CPU
synchronization to run into a timeout induced hang.
- Remove Skylake C2 from the microcode blacklist according to the
latest Intel documentation
- Fix the VM86 POPF emulation which traps if VIP is set, but VIF is
not. Enhance the selftests to catch that kind of issue
- Annotate indirect calls/jumps for objtool on 32bit. This is not a
functional issue, but for consistency sake its the right thing to
do.
- Fix a jump label build warning observed on SPARC64 which uses 32bit
storage for the code location which is casted to 64 bit pointer w/o
extending it to 64bit first.
- Add two new cpufeature bits. Not really an urgent issue, but
provides them for both x86 and x86/kvm work. No impact on the
current kernel"
