Copy stable/11@r303970 to releng/11.0 as part of the 11.0-RELEASE
cycle.

Prune svn:mergeinfo from the new branch, and rename it to RC1.

Update __FreeBSD_version.

Use the quarterly branch for the default FreeBSD.conf pkg(8) repo and
the dvd1.iso packages population.

Do a proper emulation of guest writes to MSR_EFER.
- Must-Be-Zero bits cannot be set.
- EFER_LME and EFER_LMA should respect the long mode consistency checks.
- EFER_NXE, EFER_FFXSR, EFER_TCE can be set if allowed by CPUID capabilities.
- Flag an error if guest tries to set EFER_LMSLE since bhyve doesn't enforce
segment limits in 64-bit mode.

MFC after: 2 weeks

Allow CPUID leaf 0xD to be read as zeroes.
Linux reads this even though extended features
aren't exposed.

Support for 0xD will be expanded once AVX[2]
is exposed to the guest in upcoming work.

Add svn properties to the recently merged bhyve source files.

The pre-commit hook will not allow any commits without the svn:keywords
property in head.

Merge projects/bhyve to head.

'bhyve' was developed by grehan@ and myself at NetApp (thanks!).

Special thanks to Peter Snyder, Joe Caradonna and Michael Dexter for their
support and encouragement.

Handle CPUID leaf 0x7 now that FreeBSD is using it.
Return 0's for now.

Add support for trapping MMIO writes to local apic registers and emulating them.

The default behavior is still to present the local apic to the guest in the
x2apic mode.

Some tweaks to the CPUID support:
- Don't always pass the cpuid request to the current CPU as some nodes
we will emulate purely in software.
- Pass in the APIC ID of the virtual CPU so we can return the proper APIC
ID.
- Always report a completely flat topology with no SMT or multicore.
- Report the CPUID2_HV feature and implement support for the 0x40000000
CPUID level.
- Use existing constants from <machine/specialreg.h> when possible and
use cpu_feature2 when checking for VMX support.

Changes to allow the GENERIC+bhye kernel built from this branch to
run as a 1/2 CPU guest on an 8.1 bhyve host.

bhyve/inout.c
inout.h
fbsdrun.c
- Rather than exiting on accesses to unhandled i/o ports, emulate
hardware by returning -1 on reads and ignoring writes to unhandled
ports. Support the previous mode by allowing a 'strict' parameter
to be set from the command line.
The 8.1 guest kernel was vastly cut down from GENERIC and had no
ISA devices. Booting GENERIC exposes a massive amount of random
touching of i/o ports (hello syscons/vga/atkbdc).

bhyve/consport.c
dev/bvm/bvm_console.c
- implement a simplistic signature for the bvm console by returning
'bv' for an inw on the port. Also, set the priority of the console
to CN_REMOTE if the signature was returned. This works better in
an environment where multiple consoles are in the kernel (hello syscons)

bhyve/rtc.c
- return 0 for the access to RTC_EQUIPMENT (yes, you syscons)

amd64/vmm/x86.c
x86.h
- hide a bunch more CPUID leaf 1 bits from the guest to prevent
cpufreq drivers from probing.
The next step will be to move CPUID handling completely into
user-space. This will allow the full spectrum of changes from
presenting a lowest-common-denominator CPU type/feature set, to
exposing (almost) everything that the host can support.

First cut at porting the kernel portions of 221828 and 221905 from the
BHyVe reference branch to HEAD.

Import of bhyve hypervisor and utilities, part 1.
vmm.ko - kernel module for VT-x, VT-d and hypervisor control
bhyve - user-space sequencer and i/o emulation
vmmctl - dump of hypervisor register state
libvmm - front-end to vmm.ko chardev interface

bhyve was designed and implemented by Neel Natu.
