    hvmloader: add high memory e820 region if needed
    
    If the MMIO hole is large and hvmloader needs to relocate memory to
    immediately above the 4 GiB boundary, the e820 presented to the guest
    will not have a RAM region above 4 GiB.
    
    e.g., a guest with 3 GiB of memory and a 2 GiB MMIO hole will only see
    2 GiB.
    
    The required e820 memory region above 4 GiB needs to be added, and not
    just filled in.

    vmx: restore debug registers when injecting #DB traps
    
    Commit a929bee0e652 ("x86/vmx: Fix injection of #DB traps following
    XSA-156") prevents an infinite loop in certain #DB traps. However, it
    changed the behavior to not call hvm_hw_inject_trap() for #DB and #AC
    traps which which means that the debug registers are not restored
    correctly and nullified commit b56ae5b48c38 ("VMX: fix/adjust trap
    injection").
    
    To fix this, restore the original code path through hvm_inject_trap(),
    but ensure that the struct hvm_trap is populated with all the required
    data.

    x86: don't flush the whole cache when changing cachability
    
    Introduce the FLUSH_VA_VALID flag to flush_area_mask() and friends to
    say that it is safe to use CLFLUSH (i.e., the virtual address is still
    valid).
    
    Use this when changing the cachability of the Xen direct mappings (in
    response to the guest changing the cachability of its mappings). This
    significantly improves performance by avoiding an expensive WBINVD.
    
    This fixes a performance regression introduced by
    c61a6f74f80eb36ed83a82f713db3143159b9009 (x86: enforce consistent
    cachability of MMIO mappings), the fix for XSA-154.
    
    e.g., A set_memory_wc() call in Linux:
    
    before: 4097 us
    after:    47 us

    x86/alternatives: correct near branch check
    
    Make sure the near JMP/CALL check doesn't consume uninitialized
    data, not even in a benign way. And relax the length check at once.

    x86/vPMU: do not clobber IA32_MISC_ENABLE
    
    The VMX RDMSR intercept for MSR_IA32_MISC_ENABLE falls through into
    vpmu_do_rdmsr(), so that core2_vpmu_do_rdmsr() may play with the PTS and 
PEBS
    UNAVAIL bits.
    
    Some 64bit Windows include IA32_MISC_ENABLE in the set of items checked by
    PatchGuard, and will suffer a BSOD 0x109 CRITICAL_STRUCTURE_CORRUPTION if 
the
    contents change on migrate.
    
    The vPMU infrastructure should not clobber IA32_MISC_ENABLE at all.
