It looks like when I went to add the interlaced bits, I just took the
existing PV_VERT* block and indented it, instead of copy and pasting
it first. Without this, changing resolution never worked.

If the firmware hadn't brought up HDMI for us, we need to do its

We'd need X to queue up an async pageflip while another is
outstanding, and then take a SIGIO. I think X actually avoids sending
out the next pageflip while one's already queued, but I'm not sure.

Commit d63c7dd5bcb9 ("ipr: Fix out-of-bounds null overwrite") removed
the end of line handling when storing the update_fw sysfs attribute.
This changed the userpace API because it started refusing writes
terminated by a line feed, which broke the update tools we already have.
This patch re-adds that handling, so both a write terminated by a line
feed or not can make it through with the update.

When the send skbuff reaches the end, nlmsg_put and friends returns
-EMSGSIZE but it is silently thrown away in ndo_fdb_dump. It is called
within a for_each_netdev loop and the first fdb entry of a following
netdev could fit in the remaining skbuff. This breaks the mechanism
of cb->args[0] and idx to keep track of the entries that are already
dumped, which results missing entries in bridge fdb show command.

Commit dd006da21646 ("arm64: mm: increase VA range of identity map") made
some changes to the memory mapping code to allow physical memory to reside
at an offset that exceeds the size of the virtual mapping.
However, since the size of the vmemmap area is proportional to the size of
the VA area, but it is populated relative to the physical space, we may
end up with the struct page array being mapped outside of the vmemmap
region. For instance, on my Seattle A0 box, I can see the following output
in the dmesg log.
vmemmap : 0xffffffbdc0000000 - 0xffffffbfc0000000 ( 8 GB maximum)
0xffffffbfc0000000 - 0xffffffbfd0000000 ( 256 MB actual)
We can fix this by deciding that the vmemmap region is not a projection of
the physical space, but of the virtual space above PAGE_OFFSET, i.e., the
linear region. This way, we are guaranteed that the vmemmap region is of
sufficient size, and we can even reduce the size by half.

Commit 172b2386ed16 ("KVM: x86: fix missed hardware breakpoints",
2016-02-10) worked around a case where the debug registers are not loaded
correctly on preemption and on the first entry to KVM_RUN.
However, Xiao Guangrong pointed out that the root cause must be that
KVM_DEBUGREG_BP_ENABLED is not being set correctly. This can indeed
happen due to the lazy debug exit mechanism, which does not call
kvm_update_dr7. Fix it by replacing the existing loop (more or less
equivalent to kvm_update_dr0123) with calls to all the kvm_update_dr*
functions.

Since commit 27a4c827c34ac4256a190cc9d24607f953c1c459
fbcon: use the cursor blink interval provided by vt
two attempts have been made at fixing a possible hang caused by
cursor_timer_handler. That function registers a timer to be triggered at
"jiffies + fbcon_ops.cur_blink_jiffies".
A new case had been encountered during initialisation of clcd-pl11x:
fbcon_fb_registered
do_fbcon_takeover
-> do_register_con_driver
fbcon_startup
(A) add_cursor_timer (with cur_blink_jiffies = 0)
-> do_bind_con_driver
visual_init
fbcon_init
(B) cur_blink_jiffies = msecs_to_jiffies(vc->vc_cur_blink_ms);
If we take an softirq anywhere between A and B (and we do),
cursor_timer_handler executes indefinitely.
Instead of patching all possible paths that lead to this case one at a
time, fix the issue at the source and initialise cur_blink_jiffies to
200ms when allocating fbcon_ops. This was its default value before
aforesaid commit. fbcon_cursor or fbcon_init will refine this value
downstream.

Currently the interrupt handler of HD-audio driver assumes that no irq
update is needed while processing the irq. But in reality, it has
been confirmed that the HW irq is issued even during the irq
handling. Since we clear the irq status at the beginning, process the
interrupt, then exits from the handler, the lately issued interrupt is
left untouched without being properly processed.
This patch changes the interrupt handler code to loop over the
check-and-process. The handler tries repeatedly as long as the IRQ
status are turned on, and either stream or CORB/RIRB is handled.
For checking the stream handling, snd_hdac_bus_handle_stream_irq()
returns a value indicating the stream indices bits. Other than that,
the change is only in the irq handler itself.

gs_destroy_candev() erroneously calls kfree() on a struct gs_can *, which is
allocated through alloc_candev() and should instead be freed using
free_candev() alone.
The inappropriate use of kfree() causes the kernel to hang when
gs_destroy_candev() is called.
Only the struct gs_usb * which is allocated through kzalloc() should be freed
using kfree() when the device is disconnected.

Pull tracing fix from Steven Rostedt:
"Another small bug reported to me by Chunyu Hu.
When perf added a "reg" function to the function tracing event (not a
tracepoint), it caused that event to be displayed as a tracepoint and
could cause errors in tracepoint handling. That was solved by adding
a flag to ignore ftrace non-tracepoint events. But that flag was
missed when displaying events in available_events, which should only
contain tracepoint events.
This broke a documented way to enable all events with:
cat available_events > set_event
As the function non-tracepoint event would cause that to error out.
The commit here fixes that by having the available_events file not
list events that have the ignore flag set"

Pull libnvdimm fixes from Dan Williams:
- Two fixes for compatibility with the ACPI 6.1 specification.
Without these fixes multi-interface DIMMs will fail to be probed, and
address range scrub commands to find memory errors will give results
that the kernel will mis-interpret. For multi-interface DIMMs Linux
will accept either the original 6.0 implementation or 6.1.
For address range scrub we'll only support 6.1 since ACPI formalized
this DSM differently than the original example [1] implemented in
v4.2. The expectation is that production systems will only ever ship
the ACPI 6.1 address range scrub command definition.
- The wider async address range scrub work targeting 4.6 discovered
that the original synchronous implementation in 4.5 is not sizing its
return buffer correctly.
- Arnd caught that my recent fix to the size of the pfn_t flags missed
updating the flags variable used in the pmem driver.

After a change to the snd_jack structure, the 'name' member

include/trace/events/asoc.h:240:32: error: 'struct snd_jack' has no member named 'name'
The name field is normally initialized from the card shortname and
the jack "id" field:
snprintf(jack->name, sizeof(jack->name), "%s %s",
card->shortname, jack->id);
This changes the tracing output to just contain the 'id' by
itself, which slightly changes the output format but avoids the
link error and is hopefully still enough to see what is going on.

The current default configuration is as follows:
- Invert VSYNC signal (active LOW)
- Invert HSYNC signal (active LOW)
The mode flags allow to specify the required polarity per
mode. Furthermore, none of the current driver settings is
actually a standard polarity.
This patch applies the current driver default polarities as
explicit flags to the display which has been introduced with
the driver (NEC WQVGA "nec,nl4827hc19-05b"). The driver now
also parses the flags field and applies the configuration
accordingly, by using the following values as standard
polarities: (e.g. when no flags are specified):
- VSYNC signal not inverted (active HIGH)
- HSYNC signal not inverted (active HIGH)

Fix alpha blending by enabling alpha blending for the whole frame if
a color mode with alpha channel is selected (DRM_FORMAT_ARGB*). Also
support color modes without alpha channel (DRM_FORMAT_XRGB*) by just
not enabling alpha blending on layer level.

The state of the interrupt mask register on initialization is
unknown, e.g. U-Boot could already used the DCU. So depending on
the boot loader, the outcome of the interrupt mask register could
be different. A defined state is much more preferable. Also, there
is no value in keeping interrupts enabled which we don't need.
Therefor, mask all interrupts on initialization.

If initialization fails (e.g. due to missing panel node or deferred
probe) make sure to roll-back all operations and return the error
code.

Improve error handling during CRTC initialization. Especially avoid
memory leaks in the primary plane initialization error path.
