maximal input report size instead of wMaxPacketSize.
If the USB frame length is set to 1024 bytes, WMT_BSIZE, the EETI controller
will pack multiple touch events in the packet and the current code will only
process the first touch event.
As a result some important events are lost like releasing the finger from the
touchscreen.
Use the maximal input report size as buffer size instead.

Limiting frame size to maximum packet size breaks devices which have input
report size larger than wMaxPacketSize. Maximal input report size should be
used instead.

The FUSE protocol allows the client (kernel) to cache a file's size, if the
server (userspace daemon) allows it. A well-behaved daemon obviously should
not change a file's size while a client has it cached. But a buggy daemon
might. If the kernel ever detects that that has happened, then it should
invalidate the entire cache for that file. Previously, we would not only
cache stale data, but in the case of a file extension while we had the size
cached, we accidentally extended the cache with zeros.

It's used in exactly one place. In that place it's used so we can hold the lock
on the device associated with the path (since we do a xpt_path_lock and unlock
pair around the callback). Instead, inline taking and dropping the reference to
the device so we can ensure we can unlock the mutex after the callback finishes
if the path in the ccb that's queued to be processed by xpt_scanner_thread is
destroyed while being processed. We don't actually need the path itself for
anything other than dereferencing it to get the device to do the lock and
unlock.
This also makes the locking / use model for cam_path a little cleaner by
eliminating a case where we needlessly copy the object.

These flags have been unused for some time. Some of them were in the
CAM2 specification, but CAM has moved on a bit from that. Some were
used in the old Pluto VideoSpace (and AirSpace) systems which had the
video playback I/O scheduler in userspace, but have been unused since
then.

When clearing sigfastblock, either by sigfastblock(UNSETPTR) call or
implicitly on execve(2), kernel must check for pending signals and
reschedule them if needed.
E.g. on execve, all other threads are terminated, and current thread
fast block pointer is cleaned. If any signal was left pending, it can
now be delivered to the current thread, and we should prepare for
ast() on return to userspace to notice the signals.

This speeds up Windows guests tremendously.
The patch does:
Add a new tuneable 'hw.vmm.vmx.use_tpr_shadowing' to disable TLP shadowing.
Also add 'hw.vmm.vmx.cap.tpr_shadowing' to be able to query if TPR shadowing is used.
Detach the initialization of TPR shadowing from the initialization of APIC virtualization.
APIC virtualization still needs TPR shadowing, but not vice versa.
Any CPU that supports APIC virtualization should also support TPR shadowing.
When TPR shadowing is used, the APIC page of each vCPU is written to the VMCS_VIRTUAL_APIC field of the VMCS
so that the CPU can write directly to the page without intercept.
On vm exit, vlapic_update_ppr() is called to update the PPR.

Summary:
This is largely a straight-forward cleave of the 32-bit and 64-bit page
table specifics, along with the mmu_booke_*() functions that are wholely
different between the two implementations.
The ultimate goal of this is to make it easier to reason about and
update a specific implementation without wading through the other
implementation details. This is in support of further changes to the 64-bit
pmap.

When iicbus is attached as child of Designware I2C controller it scans all
ACPI nodes for "I2C Serial Bus Connection Resource Descriptor" described
in section 19.6.57 of ACPI specs.
If such a descriptor is found, I2C child is added to iicbus, it's I2C
address, IRQ resource and ACPI handle are added to ivars. Existing
ACPI bus-hosted child is deleted afterwards.
The driver also installs so called "I2C address space handler" which is
disabled by default as nontested.
Set hw.iicbus.enable_acpi_space_handler loader tunable to 1 to enable it.
