    x86emul/test: don't use *_len symbols
    
    ... as they don't work as intended with -fPIC.
    
    I did prefer them over *_end ones at the time because older gcc would
    cause .L* symbols to be public, due to issuing .globl for all
    referenced externals. And labels at the end of instructions collide
    with the ones at the start of the next instruction, making disassembly
    harder to grok. Luckily recent gcc no longer issues those .globl
    directives, and hence .L* labels, staying local by default, no longer
    get in the way.

    x86/spec-ctrl: Introduce options to control VERW flushing
    
    The Microarchitectural Data Sampling vulnerability is split into categories
    with subtly different properties:
    
     MLPDS - Microarchitectural Load Port Data Sampling
     MSBDS - Microarchitectural Store Buffer Data Sampling
     MFBDS - Microarchitectural Fill Buffer Data Sampling
     MDSUM - Microarchitectural Data Sampling Uncacheable Memory
    
    MDSUM is a special case of the other three, and isn't distinguished further.
    
    These issues pertain to three microarchitectural buffers.  The Load Ports, 
the
    Store Buffers and the Fill Buffers.  Each of these structures are flushed by
    the new enhanced VERW functionality, but the conditions under which flushing
    is necessary vary.
    
    For this concise overview of the issues and default logic, the abbreviations
    SP (Store Port), FB (Fill Buffer), LP (Load Port) and HT (Hyperthreading) 
are
    used for brevity:
    
     * Vulnerable hardware is divided into two categories - parts which suffer
       from SP only, and parts with any other combination of vulnerabilities.
    
     * SP only has an HT interaction when the thread goes idle, due to the 
static
       partitioning of resources.  LP and FB have HT interactions at all points,
       due to the competitive sharing of resources.  All issues potentially leak
       data across the return-to-guest transition.
    
     * The microcode which implements VERW flushing also extends MSR_FLUSH_CMD, 
so
       we don't need to do both on the HVM return-to-guest path.  However, the
       Knights range of processors are immune to L1TF (therefore have no
       MSR_FLUSH_CMD), but are vulnerable to MDS, so do require VERW on the HVM
       path.
    
    Note that we deliberately support mds=1 even without MD_CLEAR in case the
    microcode has been updated but the feature bit not exposed.

    x86/spec-ctrl: Infrastructure to use VERW to flush pipeline buffers
    
    Three synthetic features are introduced, as we need individual control of
    each, depending on circumstances.  A later change will enable them at
    appropriate points.
    
    The verw_sel field doesn't strictly need to live in struct cpu_info.  It 
lives
    there because there is a convenient hole it can fill, and it reduces the
    complexity of the SPEC_CTRL_EXIT_TO_{PV,HVM} assembly by avoiding the need 
for
    any temporary stack maintenance.

    x86/boot: Detect the firmware SMT setting correctly on Intel hardware
    
    While boot_cpu_data.x86_num_siblings is an accurate value to use on AMD
    hardware, it isn't on Intel when the user has disabled Hyperthreading in the
    firmware.  As a result, a user which has chosen to disable HT still gets
    nagged on L1TF-vulnerable hardware when they haven't chosen an explicit
    smt=<bool> setting.
    
    Make use of the largely-undocumented MSR_INTEL_CORE_THREAD_COUNT which in
    practice exists since Nehalem, when booting on real hardware.  Fall back to
    using the ACPI table APIC IDs.
    
    While adjusting this logic, fix a latent bug in amd_get_topology().  The
    thread count field in CPUID.0x8000001e.ebx is documented as 8 bits wide,
    rather than 2 bits wide.

    x86/msr: Definitions for MSR_INTEL_CORE_THREAD_COUNT
    
    This is a model specific register which details the current configuration
    cores and threads in the package.  Because of how Hyperthread and Core
    configuration works works in firmware, the MSR it is de-facto constant and
    will remain unchanged until the next system reset.
    
    It is a read only MSR (so unilaterally reject writes), but for now retain 
its
    leaky-on-read properties.  Further CPUID/MSR work is required before we can
    start virtualising a consistent topology to the guest, and retaining the old
    behaviour is the safest course of action.
