    x86/hvm: Constify the read side of vlapic handling
    
    This is in preparation to make hvm_x2apic_msr_read() take a const vcpu
    pointer.  One modification is to alter vlapic_get_tmcct() to not use 
current.
    
    This in turn needs an alteration to hvm_get_guest_time_fixed(), which is 
safe
    because the only mutable action it makes is to take the domain plt lock.

    x86/vmx: Simplfy the default cases in vmx_msr_{read,write}_intercept()
    
    The default case of vmx_msr_write_intercept() in particular is very tangled.
    
    First of all, fold long_mode_do_msr_{read,write}() into their callers.  
These
    functions were split out in the past because of the 32bit build of Xen, but 
it
    is unclear why the cases weren't simply #ifdef'd in place.
    
    Next, invert the vmx_write_guest_msr()/is_last_branch_msr() logic to break 
if
    the condition is satisfied, rather than nesting if it wasn't.  This allows 
the
    wrmsr_hypervisor_regs() call to be un-nested with respect to the other 
default
    logic.
    
    No practical difference from a guests point of view.

commit b68c4f1ebe4f413076c4915733a61c818b7dc73a

    x86/hvm: fix domain crash when CR3 has the noflush bit set
    
    In hardware, when PCID support is enabled and the NOFLUSH bit is set
    when writing a CR3 value, the hardware will clear that that bit and
    change the CR3 without flushing the TLB. hvm_set_cr3(), however, was
    ignoring this bit; the result was that post-vm_event checks detected
    an invalid CR3 value and crashed the domain.
    
    Handle NOFLUSH in hvm_set_cr3() by:
    1. Clearing the bit
    2. Passing a "noflush" flag to lower-level cr3 setting functions to
    indicate that a flush should not be performed.
    
    Also clear X86_CR3_NOFLUSH when reporting CR3 monitored CR3 writes.
    
    This allows introspection to be used on VMs whose operating system uses
    the NOFLUSH bit.
