Oppv2 add more flexibility on regulator value for the core voltage amongst
other new thing.
For now only shared opp table is supported as I don't have hardware with
non-shared opp table.

In order to setup an initial environment and jump into the generic
hammer_time initialization function. Some of the code is shared with
PVHv1, while other code is PVHv2 specific.
This allows booting FreeBSD as a PVHv2 DomU and Dom0.

Allow the hypercall page to be initialized very early, even before
vtophys is functional. Also make the function global so it can be
called by other files.
This will be needed in order to perform the early bringup on PVHv2
guests.

When booted as PVHv2, there's no ACPI CPU object, so attach the PV CPU
device in order to take it's place.
This is required in case some device or driver tries to poke at the
PCPU device field.

HYPERVISOR_start_info is only available to PV and PVHv1 guests, HVM
and PVHv2 guests get this data from HVM parameters that are fetched
using a hypercall.
Instead provide a set of helper functions that should be used to fetch
this data. The helper functions have different implementations
depending on whether FreeBSD is running as PVHv1 or HVM/PVHv2 guest
type.
This helps to cleanup generic Xen code by removing quite a lot of
xen_pv_domain and xen_hvm_domain macro usages.

The PVHv2 entry point is fairly similar to the multiboot1 one. The
kernel is started in protected mode with paging disabled. More
information about the exact BSP state can be found in the pvh.markdown
document on the Xen tree.
This entry point is going to be joined with the native entry point at
hammer_time, and in order to do so the BSP needs to be bootstrapped
into long mode with the same set of page tables as used on bare metal.

This is a trivial comment-only fix. The man page for kevent(2) gives
the definition of struct kevent, including a comment on each
field. The actual definition in sys/event.h omitted the comments on
some fields. Add the comments in. Not only does this make the man page
and include file agree, but the comments are useful in and of
themselves.

Query the minimal inline mode supported by the card.
When creating a send queue, cache the queried mode and optimize the transmit
if no inlining is required. In this case, we can avoid touching the headers
cache line and avoid dirtying several more lines by copying headers into
the send WQEs. Also, if no inline headers are used, hardware assists in
the VLAN tag framing.

Track session objects in the framework, and pass handles between the
framework (OCF), consumers, and drivers. Avoid redundancy and complexity in
individual drivers by allocating session memory in the framework and
providing it to drivers in ::newsession().
Session handles are no longer integers with information encoded in various
high bits. Use of the CRYPTO_SESID2FOO() macros should be replaced with the
appropriate crypto_ses2foo() function on the opaque session handle.
Convert OCF drivers (in particular, cryptosoft, as well as myriad others) to
the opaque handle interface. Discard existing session tracking as much as
possible (quick pass). There may be additional code ripe for deletion.
Convert OCF consumers (ipsec, geom_eli, krb5, cryptodev) to handle-style
interface. The conversion is largely mechnical.
The change is documented in crypto.9.

up serial output. Setting the cursor position after every character is
inefficient, and causes all lines to be over-printed in the serial
console for the boot loader. Allow the terminal to do the emulation.
This isn't completely perfect when the size of the terminal attached
to the serial port isn't the same as 80x25 to match the viedoe console
(or whatever the video console is). While imperfect still, these
changes make it much better.
This makes the serial port useful with UEFI.
