MFC 258859,259081,259085,259205,259213,259275,259482,259537,259702,259779: Several changes to the local APIC support in bhyve: - Rename 'vm_interrupt_hostcpu()' to 'vcpu_notify_event()'. - If a vcpu disables its local apic and then executes a 'HLT' then spin down the vcpu and destroy its thread context. Also modify the 'HLT' processing to ignore pending interrupts in the IRR if interrupts have been disabled by the guest. The interrupt cannot be injected into the guest in any case so resuming it is futile. - Use callout(9) to drive the vlapic timer instead of clocking it on each VM exit. - When the guest is bringing up the APs in the x2APIC mode a write to the ICR register will now trigger a return to userspace with an exitcode of VM_EXITCODE_SPINUP_AP. - Change the vlapic timer lock to be a spinlock because the vlapic can be accessed from within a critical section (vm run loop) when guest is using x2apic mode. - Fix the vlapic version register. - Add a command to bhyvectl to inject an NMI on a specific vcpu. - Add an API to deliver message signalled interrupts to vcpus. This allows callers to treat the MSI 'addr' and 'data' fields as opaque and also lets bhyve implement multiple destination modes: physical, flat and clustered. - Rename the ambiguously named 'vm_setup_msi()' and 'vm_setup_msix()' to 'vm_setup_pptdev_msi()' and 'vm_setup_pptdev_msix()' respectively. - Consolidate the virtual apic initialization in a single function: vlapic_reset() - Add a generic routine to trigger an LVT interrupt that supports both fixed and NMI delivery modes. - Add an ioctl and bhyvectl command to trigger local interrupts inside a guest. In particular, a global NMI similar to that raised by SERR# or PERR# can be simulated by asserting LINT1 on all vCPUs. - Extend the LVT table in the vCPU local APIC to support CMCI. - Flesh out the local APIC error reporting a bit to cache errors and report them via ESR when ESR is written to. Add support for asserting the error LVT when an error occurs. Raise illegal vector errors when attempting to signal an invalid vector for an interrupt or when sending an IPI. - Export table entries in the MADT and MP Table advertising the stock x86 config of LINT0 set to ExtInt and LINT1 wired to NMI.

Return 0 for a rdmsr of MSR_IA32_PLATFORM_ID. This is enough to get Ubuntu 12.0.4/13.0.4 to boot.

Emulate reading of the IA32_MISC_ENABLE MSR, by returning the host MSR and masking off features that aren't supported. Linux reads this MSR to detect if NX has been disabled via BIOS.

Change emulate_rdmsr() and emulate_wrmsr() to return 0 on sucess and errno on failure. The conversion from the return value to HANDLED or UNHANDLED can be done locally in vmx_exit_process().

Restructure the x2apic access code in preparation for supporting memory mapped access to the local apic.
The vlapic code is now aware of the mode that the guest is using to access the local apic.

Add support for running as a nested hypervisor under VMWare Fusion, on systems with VT-x/EPT (e.g. Sandybridge Macbooks). This will most likely work on VMWare Workstation8/Player4 as well. See the VMWare app note at:
http://communities.vmware.com/docs/DOC-8970
Fusion doesn't propagate the PAT MSR auto save-restore entry/exit control bits. Deal with this by noting that fact and setting up the PAT MSR to essentially be a no-op - it is init'd to power-on default, and a software shadow copy maintained.
Since it is treated as a no-op, o/s settings are essentially ignored. This may not give correct results, but since the hypervisor is running nested, a number of bets are already off.
On a quad-core/HT-enabled 'MacBook8,2', nested VMs with 1/2/4 vCPUs were fired up. The more nested vCPUs the worse the performance, unless the VMs were started up in multiplexed mode where things worked perfectly up to the limit of 8 vCPUs.
