After r325072 stale lib32 dependencies were not remooved. A more
holistic approach is needed to address this but for the immediate issue
(-DNO_CLEAN builds across r358851) just readd the explicit lib32 path.

The openmp 10.0.0 import renamed one .c file to .cpp, and this is

The SCR, scratch register was not present on the 8250 and 8250B UART, so we
can use to test if we actually do have serial port.
We need this test because some systems will get long delays while attempting
to write to non-existing port and this will slow down the console IO
to extreme.

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.

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.
