ioctl USBTMC_IOCTL_WRITE_RESULT copies current out_transfer_size
to given __u32 pointer and returns current out_status of the last
(asnynchronous) USBTMC_IOCTL_WRITE call.

The new ioctl USBTMC_IOCTL_WRITE sends a generic message to bulk OUT.
This ioctl is used for vendor specific or asynchronous I/O as well.
The message is split into chunks of 4k (page size).
Message size is aligned to 32 bit boundaries.
With flag USBTMC_FLAG_ASYNC the ioctl is non blocking.
With flag USBTMC_FLAG_APPEND additional urbs are queued and
out_status/out_transfer_size is not reset. EPOLLOUT | EPOLLWRNORM
is signaled when all submitted urbs are completed.
Flush flying urbs when file handle is closed or device is
suspended or reset.
This ioctl does not support compatibility for 32 bit
applications running on 64 bit systems. However all other
convenient ioctls of the USBTMC driver can still be used in 32
bit applications as well. Note that 32 bit applications running
on 32 bit target systems are not affected by this limitation.

There are now generic usb-connector bindings which can be used
to define a port controllers configuration for USB-PD, so device
specific bindings are no longer necessary.
This update deprecates 'fcs,operating-sink-microwatt', and references
the 'usb-connector' bindings instead to achieve the required port
config.

usb_find_alt_setting() takes a pointer to a struct usb_host_config as
an argument; it searches for an interface with specified interface and
alternate setting numbers in that config. However, it crashes if the
usb_host_config pointer argument is NULL.
Since this is a general-purpose routine, available for use in many
places, we want to to be more robust. This patch makes it return NULL
whenever the config argument is NULL.

The syzbot fuzzing project found a use-after-free bug in the USB
core. The bug was caused by usbfs not unbinding from an interface
when the USB device file was closed, which led another process to
attempt the unbind later on, after the private data structure had been
deallocated.
The reason usbfs did not unbind the interface at the appropriate time
was because it thought the interface had never been claimed in the
first place. This was caused by the fact that
usb_driver_claim_interface() does not clean up properly when
device_bind_driver() returns an error. Although the error code gets
passed back to the caller, the iface->dev.driver pointer remains set
and iface->condition remains equal to USB_INTERFACE_BOUND.
This patch adds proper error handling to usb_driver_claim_interface().

usb_driver_claim_interface() disables and re-enables Link Power
Management, but it shouldn't do either one, for the reasons listed
below. This patch removes the two LPM-related function calls from the
routine.
The reason for disabling LPM in the analogous function
usb_probe_interface() is so that drivers won't have to deal with
unwanted LPM transitions in their probe routine. But
usb_driver_claim_interface() doesn't call the driver's probe routine
(or any other callbacks), so that reason doesn't apply here.
Furthermore, no driver other than usbfs will ever call
usb_driver_claim_interface() unless it is already bound to another
interface in the same device, which means disabling LPM here would be
redundant. usbfs doesn't interact with LPM at all.
Lastly, the error return from usb_unlocked_disable_lpm() isn't handled
properly; the code doesn't clean up its earlier actions before
returning.

TI AM335x CPPI 4.1 module uses a single register bit for CPPI interrupts
in both musb controllers. So disabling the CPPI irq in one musb driver
breaks the other musb module.
Since musb is already disabled before tearing down dma controller in
musb_remove(), it is safe to not disable CPPI irq in
musb_dma_controller_destroy().

In multi-function mode, driver receives the stag value (outer vlan)
for a PF from management FW (MFW). If the stag value is negotiated prior to
the driver load, then the stag is not notified to the driver and hence
driver will have the invalid stag value.
The fix is to request the MFW for STAG value during the driver load time.

mpe: This was fixed originally in commit d3d4ffaae439
("powerpc/powernv/ioda2: Reduce upper limit for DMA window size"), but
contrary to what the merge commit says was inadvertently lost by me in
commit ce57c6610cc2 ("Merge branch 'topic/ppc-kvm' into next") which
brought in changes that moved the code to a new file. So reapply it to
the new file.
Original commit message follows:
We use PHB in mode1 which uses bit 59 to select a correct DMA window.
However there is mode2 which uses bits 59:55 and allows up to 32 DMA
windows per a PE.
Even though documentation does not clearly specify that, it seems that
the actual hardware does not support bits 59:55 even in mode1, in
other words we can create a window as big as 1<<58 but DMA simply
won't work.
This reduces the upper limit from 59 to 55 bits to let the userspace
know about the hardware limits.

This change addresses the issue adding the needed check before
accessing the inner header.
The ipv4 side of the issue is apparently there since the ipv4 over ipv6
initial support, and the ipv6 side predates git history.

pull request for net: batman-adv 2018-09-19
here are some bugfixes which we would like to see integrated into net.
We forgot to bump the version number in the last round for net-next, so
the belated patch to do that is included - we hope you can adopt it.
This will most likely create a merge conflict later when merging into
net-next with this rounds net-next patchset, but net-next should keep
the 2018.4 version[1].

drm-misc-fixes for v4.19-rc5:
- Fix crash in vgem in drm_drv_uses_atomic_modeset.
- Allow atomic drivers that don't set DRIVER_ATOMIC to create debugfs entries.
- Fix compiler warning for unused connector_funcs.
- Fix null pointer deref on UDL unplug.
- Disable DRM support for sun4i's R40 for now.
(Not all patches went in for v4.19, so it has to wait a cycle.)
- NULL-terminate the of_device_id table in pl111.
- Make sure vc4 NV12 planar format works when displaying an unscaled fb.

Test guest access to MSR_PLATFORM_INFO when the capability is enabled

Add KVM_CAP_MSR_PLATFORM_INFO so that userspace can disable guest access
to reads of MSR_PLATFORM_INFO.
Disabling access to reads of this MSR gives userspace the control to "expose"
this platform-dependent information to guests in a clear way. As it exists
today, guests that read this MSR would get unpopulated information if userspace
hadn't already set it (and prior to this patch series, only the CPUID faulting
information could have been populated). This existing interface could be
confusing if guests don't handle the potential for incorrect/incomplete
information gracefully (e.g. zero reported for base frequency).

Allow userspace to set turbo bits in MSR_PLATFORM_INFO. Previously, only
the CPUID faulting bit was settable. But now any bit in
MSR_PLATFORM_INFO would be settable. This can be used, for example, to
convey frequency information about the platform on which the guest is
running.

In case L1 do not intercept L2 HLT or enter L2 in HLT activity-state,
it is possible for a vCPU to be blocked while it is in guest-mode.
According to Intel SDM 26.6.5 Interrupt-Window Exiting and
Virtual-Interrupt Delivery: "These events wake the logical processor
if it just entered the HLT state because of a VM entry".
Therefore, if L1 enters L2 in HLT activity-state and L2 has a pending
deliverable interrupt in vmcs12->guest_intr_status.RVI, then the vCPU
should be waken from the HLT state and injected with the interrupt.
In addition, if while the vCPU is blocked (while it is in guest-mode),
it receives a nested posted-interrupt, then the vCPU should also be
waken and injected with the posted interrupt.
To handle these cases, this patch enhances kvm_vcpu_has_events() to also
check if there is a pending interrupt in L2 virtual APICv provided by
L1. That is, it evaluates if there is a pending virtual interrupt for L2
by checking RVI[7:4] > VPPR[7:4] as specified in Intel SDM 29.2.1
Evaluation of Pending Interrupts.
Note that this also handles the case of nested posted-interrupt by the
fact RVI is updated in vmx_complete_nested_posted_interrupt() which is
called from kvm_vcpu_check_block() -> kvm_arch_vcpu_runnable() ->
kvm_vcpu_running() -> vmx_check_nested_events() ->
vmx_complete_nested_posted_interrupt().

kvm_load_guest_fpu()
kvm_put_guest_fpu()
are only used locally, make them static. This requires also that both
functions are moved because they are used before their implementation.

e5bb40251a920 ("KVM: Drop kvm_{load,put}_guest_fpu() exports").
