    Shifting into the sign bit of an integer is undefined behaviour.
    
    Only the first integer is actually undefined, but switch all the shifts

    xen: Remove buggy initial placement algorithm
    
    The initial placement algorithm sometimes picks cpus outside of the
    mask it's given, does a lot of unnecessary bitmasking, does its own
    separate load calculation, and completely ignores vcpu hard and soft
    affinities.  Just get rid of it and rely on the schedulers to do
    initial placement.

    xen: Have schedulers revise initial placement
    
    The generic domain creation logic in
    xen/common/domctl.c:default_vcpu0_location() attempts to try to do
    initial placement load-balancing by placing vcpu 0 on the least-busy
    non-primary hyperthread available.  Unfortunately, the logic can end
    up picking a pcpu that's not in the online mask.  When this is passed
    to a scheduler such which assumes that the initial assignment is
    valid, it causes a null pointer dereference looking up the runqueue.
    
    Furthermore, this initial placement doesn't take into account hard or
    soft affinity, or any scheduler-specific knowledge (such as historic
    runqueue load, as in credit2).
    
    To solve this, when inserting a vcpu, always call the per-scheduler
    "pick" function to revise the initial placement.  This will
    automatically take all knowledge the scheduler has into account.
    
    csched2_cpu_pick ASSERTs that the vcpu's pcpu scheduler lock has been
    taken.  Grab and release the lock to minimize time spend with irqs
    disabled.

    nested vmx: Validate host VMX MSRs before accessing them
    
    Some VMX MSRs may not exist on certain processor models, or may
    be disabled because of configuration settings.   It is only safe to
    access these MSRs if configuration flags in other MSRs are set.  These
    prerequisites are listed in the Intel 64 and IA-32 Architectures
    Software Developerâ??s Manual, Vol 3, Appendix A.
    
    nvmx_msr_read_intercept() does not check the prerequisites before
    accessing MSR_IA32_VMX_PROCBASED_CTLS2, MSR_IA32_VMX_EPT_VPID_CAP,
    MSR_IA32_VMX_VMFUNC on the host.   Accessing these MSRs from a nested
    VMX guest running on a host which does not support them will cause
    Xen to crash with a GPF.

    nested vmx: intercept guest rdmsr for MSR_IA32_VMX_VMFUNC
    
    Guest reads of MSR_IA32_VMX_VMFUNC should be handled by
    the logic in vmx_msr_read_intercept().   Otherwise a guest
    can read the raw host value of this MSR, even if nested
    vmx is disabled.
