Add the report_size to struct asus_touchpad_info instead of calculating it.
This is a preparation patch for adding support for the multi-touch touchpad
found on the Medion Akoya E1239T's keyboard-dock, which uses the same
custom multi-touch protocol as the Asus keyboard-docks (same chipset
vendor, Integrated Technology Express / ITE).
The only difference in that the Akoya E1239T keyboard-dock's input-reports
have a 5 byte footer instead of a 1 byte footer, which requires the
report_size to be configurable per touchpad-model.

Add a hid_is_using_ll_driver(usb_hid_driver) check to ensure that the

Before this commit the code was trying to keep the mapping for the
left mouse-button, do avoid the hidinput_has_been_populated() check
in hid-input.c from triggering and causing the touchpad input_dev ro
get cleaned up.
But the hidinput_has_been_populated() check happens after the
input_configured callback which sets up all the input bit for the
touchpad, so there is no need to preserve the left button mapping.

Make asus_input_mapping() only set EV_REP if we are adding a mapping.
The T100CHI bluetooth keyboard dock has a few input reports for which
we do not create any mappings (these input-reports are present in the
descriptors but never send).
The hid-asus code relies on the HID core not creating input devices for
input-reports without any mappings. But the present of the EV_REP but
counts as a mapping causing 6 /dev/input/event# nodes to be created for
the T100CHI bluetooth keyboard dock. This change brings the amount of
created /dev/input/event# nodes / input-devices down to 4.

Hi Linus,
Please, pull the following patch that reverts changes in include/uapi/
These structures can get embedded in other structures in user-space

Due to a bug-report that was compiler-dependent, I updated one of my
machines to gcc-10. That shows a lot of new warnings. Happily they
seem to be mostly the valid kind, but it's going to cause a round of
churn for getting rid of them..
This is the really low-hanging fruit of removing a couple of zero-sized
arrays in some core code. We have had a round of these patches before,
and we'll have many more coming, and there is nothing special about
these except that they were particularly trivial, and triggered more
warnings than most.

Add a HID_QUIRK_NO_INIT_REPORTS quirk for the Dell K12A keyboard-dock,
which can be used with various Dell Venue 11 models.
Without this quirk the keyboard/touchpad combo works fine when connected
at boot, but when hotplugged 9 out of 10 times it will not work properly.
Adding the quirk fixes this.

Ning Bo reported an abnormal 2-second gap when booting Kata container [1].
The unconditional timeout was caused by VSOCK_DEFAULT_CONNECT_TIMEOUT of
connecting from the client side. The vhost vsock client tries to connect
an initializing virtio vsock server.
The abnormal flow looks like:
host-userspace vhost vsock guest vsock
============== =========== ============
connect() --------> vhost_transport_send_pkt_work() initializing
| vq->private_data==NULL
| will not be queued
V
schedule_timeout(2s)
vhost_vsock_start() <--------- device ready
set vq->private_data
wait for 2s and failed
connect() again vq->private_data!=NULL recv connecting pkt
Details:
1. Host userspace sends a connect pkt, at that time, guest vsock is under
initializing, hence the vhost_vsock_start has not been called. So
vq->private_data==NULL, and the pkt is not been queued to send to guest
2. Then it sleeps for 2s
3. After guest vsock finishes initializing, vq->private_data is set
4. When host userspace wakes up after 2s, send connecting pkt again,
everything is fine.
As suggested by Stefano Garzarella, this fixes it by additional kicking the
send_pkt worker in vhost_vsock_start once the virtio device is started. This
makes the pending pkt sent again.
After this patch, kata-runtime (with vsock enabled) boot time is reduced
from 3s to 1s on a ThunderX2 arm64 server.

A userspace process holding a file descriptor to a virtio_blk device can
still invoke block_device_operations after hot unplug. This leads to a
use-after-free accessing vblk->vdev in virtblk_getgeo() when

A related problem is that virtblk_remove() leaks the vd_index_ida index
when something still holds a reference to vblk->disk during hot unplug.
This causes virtio-blk device names to be lost (vda, vdb, etc).
Fix these issues by protecting vblk->vdev with a mutex and reference
counting vblk so the vd_index_ida index can be removed in all cases.

Currently, system fails to boot because the legacy interrupt remapping
mode does not enable 128-bit IRTE (GA), which is required for x2APIC
support.
Fix by using AMD_IOMMU_GUEST_IR_LEGACY_GA mode when booting with
kernel option amd_iommu_intr=legacy instead. The initialization
logic will check GASup and automatically fallback to using
AMD_IOMMU_GUEST_IR_LEGACY if GA mode is not supported.

while (ctx->sqo_thread && !wq_has_sleeper(&ctx->sqo_wait))

above loop never has an chance to exit, it's because preempt isn't enabled
in the kernel, and the context calling io_ring_ctx_wait_and_kill() and
io_sq_thread() run in the same cpu, if io_sq_thread calls a cond_resched()
yield cpu and another context enters above loop, then io_sq_thread() will
always in runqueue and never exit.
Use cond_resched() can fix this issue.

kunit: Add missing newline in summary message
This kselftest update for Linux 5.7-rc4 consists of:
- ftrace test fixes to check for required filter files and kprobe args.
- Kselftest build/cross-build dependency check script to make it easier
for test ring admins/users to configure build systems correctly for
build/cross-build kselftests. Currently checks library dependencies.
- Checks if Kselftests can be built/cross-built on a system running
compile test on a trivial C file with LDLIBS specified for each
individual test in their Makefiles.
- Prints suggested target list for a system filtering out tests
failed the build dependency check from the TARGETS in Selftests

- Prints pass/fail dependency check for each tests/sub-test.
- Prints pass/fail targets and libraries.
- Default: runs dependency checks on all tests.
- Optional test name can be specified to check dependencies for it.
