Pull a xen_blkfront fix from Konrad:
"It has one simple fix for the multi-queue support not showing up after
a block device was detached/re-attached."
* 'stable/for-jens-4.15' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen:
xen-blkfront: move negotiate_mq to cover all cases of new VBDs
This removes a dependency on the order options are passed when creating
a fabrics controller. With the old code, if "nr_io_queues" appears before
an "nqn" option specifying the discovery controller, then nr_io_queues
is overridden with zero. If "nr_io_queues" appears after specifying the
discovery controller, then the nr_io_queues option is used to set the
number of queues, and the driver attempts to establish IO connections
to the discovery controller (which doesn't work).
It seems better to ignore (and warn about) the "nr_io_queues" option
if userspace has already asked to connect to the discovery controller.

cmd_dt_S_dtb constructs the assembly source to incorporate a devicetree
FDT (that is, the .dtb file) as binary data in the kernel image. This
assembly source contains labels before and after the binary data. The
label names incorporate the file name of the corresponding .dtb file.
Hyphens are not legal characters in labels, so .dtb files built into the
kernel with hyphens in the file name result in errors like the
following:
bcm3368-netgear-cvg834g.dtb.S: Assembler messages:
bcm3368-netgear-cvg834g.dtb.S:5: Error: : no such section

bcm3368-netgear-cvg834g.dtb.S:9: Error: junk at end of line, first unrecognized character is `-'
Fix this by updating cmd_dt_S_dtb to transform all hyphens from the file
name to underscores when constructing the labels.
As of v4.16-rc2, 1139 .dts files across ARM64, ARM, MIPS and PowerPC
contain hyphens in their names, but the issue only currently manifests
on Broadcom MIPS platforms, as that is the only place where such files
are built into the kernel. For example when CONFIG_DT_NETGEAR_CVG834G=y,
or on BMIPS kernels when the dtbs target is used (in the latter case it
admittedly shouldn't really build all the dtb.o files, but thats a
separate issue).

usb: fixes for v4.16-rc4
Just small fixes now. The two most important are a fix for a a lock up

use-after-free fix in ffs_fs_kill_sb().
Apart from that, some DT compatible fixes.
The check_interval file in
/sys/devices/system/machinecheck/machinecheck<cpu number>
directory is a global timer value for MCE polling. If it is changed by one
CPU, mce_restart() broadcasts the event to other CPUs to delete and restart
the MCE polling timer and __mcheck_cpu_init_timer() reinitializes the
mce_timer variable.
If more than one CPU writes a specific value to the check_interval file
concurrently, mce_timer is not protected from such concurrent accesses and
all kinds of explosions happen. Since only root can write to those sysfs
variables, the issue is not a big deal security-wise.
However, concurrent writes to these configuration variables is void of
reason so the proper thing to do is to serialize the access with a mutex.
Boris:
- Make store_int_with_restart() use device_store_ulong() to filter out
negative intervals
- Limit min interval to 1 second
- Correct locking
- Massage commit message

With the previous two fixes for the write / ioctl races:
ALSA: seq: Don't allow resizing pool in use
ALSA: seq: More protection for concurrent write and ioctl races
the cells aren't any longer in queues at the point calling
snd_seq_pool_done() in snd_seq_ioctl_set_client_pool(). Hence the
function call snd_seq_queue_client_leave_cells() can be dropped safely
from there.

This patch is an attempt for further hardening against races between
the concurrent write and ioctls. The previous fix d15d662e89
("ALSA: seq: Fix racy pool initializations") covered the race of the
pool initialization at writer and the pool resize ioctl by the
client->ioctl_mutex (CVE-2018-1000004). However, basically this mutex
should be applied more widely to the whole write operation for
avoiding the unexpected pool operations by another thread.
The only change outside snd_seq_write() is the additional mutex
argument to helper functions, so that we can unlock / relock the given
mutex temporarily during schedule() call for blocking write.

Before you read any further: the early loading method is still the
preferred one and you should always do that. The following patch is
improving the late loading mechanism for long running jobs and cloud use

one-by-one to make the late update process as reliable as possible and

As:
1) It's known that hypervisors lie about the environment anyhow (host
mismatch)
2) Even if the hypervisor (Xen, KVM, VMWare, etc) provided a valid
"correct" value, it all gets to be very murky when migration happens
(do you provide the "new" microcode of the machine?).
And in reality the cloud vendors are the ones that should make sure that
the microcode that is running is correct and we should just sing lalalala

This is a fix for a (sort of) fallout in the recent commit
d15d662e89 ("ALSA: seq: Fix racy pool initializations") for
CVE-2018-1000004.
As the pool resize deletes the existing cells, it may lead to a race
when another thread is writing concurrently, eventually resulting a
UAF.
A simple workaround is not to allow the pool resizing when the pool is
in use. It's an invalid behavior in anyway.

Since Linux v3.2, vsyscalls have been deprecated and slow. From v3.2
on, Linux had three vsyscall modes: "native", "emulate", and "none".
"emulate" is the default. All known user programs work correctly in
emulate mode, but vsyscalls turn into page faults and are emulated.
This is very slow. In "native" mode, the vsyscall page is easily
usable as an exploit gadget, but vsyscalls are a bit faster -- they
turn into normal syscalls. (This is in contrast to vDSO functions,
which can be much faster than syscalls.) In "none" mode, there are
no vsyscalls.
For all practical purposes, "native" was really just a chicken bit
in case something went wrong with the emulation. It's been over six
years, and nothing has gone wrong. Delete it.

This reverts commit 4828296982 which
caused the following issues:
1. On T460p with BIOS version 2.22 touchpad and trackpoint stop working
after suspend-resume cycle. Due to strange state of the device another
suspend is impossible.
The following dmesg errors can be observed:

rmi4_physical rmi4-00: rmi_driver_set_irq_bits: Failed to change enabled interrupts!
psmouse: probe of serio3 failed with error -1
2. On another T460p with BIOS version 2.15 two finger scrolling gesture
on the touchpad stops working after suspend-resume cycle (about 75%
reproducibility, when it still works, the scrolling gesture becomes
laggy). Nothing suspicious appears in the dmesg.
Analysis form Richard Schütz:
"RMI is unreliable on the ThinkPad T460p because the device is affected
by the firmware behavior addressed in a7ae81952c ("i2c: i801: Allow
ACPI SystemIO OpRegion to conflict with PCI BAR")."
The affected devices often show:
i801_smbus 0000:00:1f.4: BIOS is accessing SMBus registers

HW Engineer's Notes:
During switch from vga->extended, if we set the VGA_TEST_ENABLE and then
hit the VGA_TEST_RENDER_START, then the DCHUBP timing gets updated correctly.
Then vBIOS will have it poll for the VGA_TEST_RENDER_DONE and unset
VGA_TEST_ENABLE, to leave it in the same state as before.

While checking plane states for updates during atomic check, we create
dc_plane_states in preparation. These dc states should be freed if
something errors.
Although the input transfer function is also freed by
dc_plane_state_release(), we should free it (on error) under the same
scope as where it is created.

Before dig fe is enabled, infoframe can't be programmed. So in
suspend resume case our infoframe programmming was not going through.
This change changes the sequence so that infoframe is programmed
after.

Move cursor programming to inside the OTG_MASTER_UPDATE_LOCK
If graphics plane go from 1 pipe to hsplit, the cursor updates
after mpc programming and unlock. Which means there is a window
of time where cursor is enabled on the wrong pipe if it's on
the right side of the screen (i.e. case where cursor need to
move from pipe 0 to pipe 3 post split). This will cause pstate hang.
Solution is to program the cursor while still locked.

Because AMDGPU_CRTC_IRQ_VLINE1 = 6, it expected 6 more crtcs to be
programed with disabled irq state in amdgpu_irq_disable_all. That caused errors and accessed
the wrong memory location.

There is no need to call drm_mode_set_crtcinfo() again once
crtc timing is decided. Otherwise non-native/unsupported timing
might get overwritten.

We've got a helper function to call dc_create_stream_for_sink and one
other place that calls it directly. Make sure we call the helper
functions always since we need to update a bunch of things in stream and
don't want to miss that.
