MFC r276428: Replace bhyve's minimal RTC emulation with a fully featured one in vmm.ko.
MFC r276432: Initialize all fields of 'struct vm_exception exception' before passing it to vm_inject_exception().
MFC r276763: Clear blocking due to STI or MOV SS in the hypervisor when an instruction is emulated or when the vcpu incurs an exception.
MFC r277149: Clean up usage of 'struct vm_exception' to only to communicate information from userspace to vmm.ko when injecting an exception.
MFC r277168: Fix typo (missing comma).
MFC r277309: Make the error message explicit instead of just printing the usage if the virtual machine name is not specified.
MFC r277310: Simplify instruction restart logic in bhyve.
MFC r277359: Fix a bug in libvmmapi 'vm_copy_setup()' where it would return success even if the 'gpa' was in the guest MMIO region.
MFC r277360: MOVS instruction emulation.
MFC r277626: Add macro to identify AVIC capability (advanced virtual interrupt controller) in AMD processors.
MFC r279220: Don't close a block context if it couldn't be opened avoiding a null deref.
MFC r279225: Add "-u" option to bhyve(8) to indicate that the RTC should maintain UTC time.
MFC r279227: Emulate MSR 0xC0011024 when running on AMD processors.
MFC r279228: Always emulate MSR_PAT on Intel processors and don't rely on PAT save/restore capability of VT-x. This lets bhyve run nested in older VMware versions that don't support the PAT save/restore capability.
MFC r279540: Fix warnings/errors when building vmm.ko with gcc.

MFC r273375 Add support AMD processors with the SVM/AMD-V hardware extensions.
MFC r273749 Remove bhyve SVM feature printf's now that they are available in the general CPU feature detection code.
MFC r273766 Add missing 'break' pointed out by Coverity CID 1249760.
MFC r276098 Allow ktr(4) tracing of all guest exceptions via the tunable "hw.vmm.trace_guest_exceptions"
MFC r276392 Inject #UD into the guest when it executes either 'MONITOR' or 'MWAIT' on an AMD/SVM host.
MFC r276402 Remove "svn:mergeinfo" property that was dragged along when these files were svn copied in r273375.

MFC r270326 Fix a recursive lock acquisition in vi_reset_dev().
MFC r270434 Return the spurious interrupt vector (IRQ7 or IRQ15) if the atpic cannot find any unmasked pin with an interrupt asserted.
MFC r270436 Fix a bug in the emulation of CPUID leaf 0x4.
MFC r270437 Add "hw.vmm.topology.threads_per_core" and "hw.vmm.topology.cores_per_package" tunables to modify the default cpu topology advertised by bhyve.
MFC r270855 Set the 'inst_length' to '0' early on before any error conditions are detected in the emulation of the task switch. If any exceptions are triggered then the guest %rip should point to instruction that caused the task switch as opposed to the one after it.
MFC r270857 The "SUB" instruction used in getcc() actually does 'x -= y' so use the proper constraint for 'x'. The "+r" constraint indicates that 'x' is an input and output register operand.
While here generate code for different variants of getcc() using a macro GETCC(sz) where 'sz' indicates the operand size.
Update the status bits in %rflags when emulating AND and OR opcodes.
MFC r271439 Initialize 'bc_rdonly' to the right value.
MFC r271451 Optimize the common case of injecting an interrupt into a vcpu after a HLT by explicitly moving it out of the interrupt shadow.
MFC r271888 Restructure the MSR handling so it is entirely handled by processor-specific code.
MFC r271890 MSR_KGSBASE is no longer saved and restored from the guest MSR save area. This behavior was changed in r271888 so update the comment block to reflect this.
MFC r271891 Add some more KTR events to help debugging.
MFC r272197 mmap(2) requires either MAP_PRIVATE or MAP_SHARED for non-anonymous mappings.
MFC r272395 Get rid of code that dealt with the hardware not being able to save/restore the PAT MSR on guest exit/entry. This workaround was done for a beta release of VMware Fusion 5 but is no longer needed in later versions.
All Intel CPUs since Nehalem have supported saving and restoring MSR_PAT in the VM exit and entry controls.
MFC r272670 Inject #UD into the guest when it executes either 'MONITOR' or 'MWAIT'.
MFC r272710 Implement the FLUSH operation in the virtio-block emulation.
MFC r272838 iasl(8) expects integer fields in data tables to be specified as hexadecimal values. Therefore the bit width of the "PM Timer Block" was actually being interpreted as 50-bits instead of the expected 32-bit.
This eliminates an error message emitted by a Linux 3.17 guest during boot: "Invalid length for FADT/PmTimerBlock: 50, using default 32"
MFC r272839 Support Intel-specific MSRs that are accessed when booting up a linux in bhyve: - MSR_PLATFORM_INFO - MSR_TURBO_RATIO_LIMITx - MSR_RAPL_POWER_UNIT
MFC r273108 Emulate "POP r/m". This is needed to boot OpenBSD/i386 MP kernel in bhyve.
MFC r273212 Support stopping and restarting the AHCI command list via toggling PxCMD.ST from '1' to '0' and back. This allows the driver a chance to recover if for instance a timeout occurred due to activity on the host.

Remove redundant code and the misleading comment that suggest otherwise. - Ignore writes to microcode update MSR. This MSR is accessed by RHEL7 guest. Add KTR tracepoints to annotate wrmsr and rdmsr VM exits. - Provide an alias for the userboot console and name it 'comconsole'. - Use EV_ADD to create an mevent and EV_ENABLE to enable it. - abort(3) the process in response to a VMEXIT_ABORT. - Don't include the guest memory segments in the bhyve(8) process core dump. - Make the vmx asm code dtrace-fbt-friendly. - Allow vmx_getdesc() and vmx_setdesc() to be called for a vcpu that is in the VCPU_RUNNING state. - Enable VMX in the IA32_FEATURE_CONTROL MSR if it not enabled and the MSR isn't locked.

Add an explicit exit code 'SPINUP_AP' to tell the controlling process that an AP needs to be activated by spinning up an execution context for it.
The local apic emulation is now completely done in the hypervisor and it will detect writes to the ICR_LO register that try to bring up the AP. In response to such writes it will return to userspace with an exit code of SPINUP_AP.
