    iommu: don't need to map dom0 page when the PT is shared
    
    Currently iommu_init_dom0 is browsing the page list and call map_page 
callback
    on each page.
    
    On both AMD and VTD drivers, the function will directly return if the page
    table is shared with the processor. So Xen can safely avoid to run through
    the page list.

    x86: expose RDSEED, ADX, and PREFETCHW to dom0
    
    This patch explicitly exposes Intel new features to dom0, including
    RDSEED and ADX. As for PREFETCHW, it doesn't need explicit exposing.

    Nested VMX: update nested paging mode on vmexit
    
    Since SVM and VMX use different mechanism to emulate the virtual-vmentry
    and virtual-vmexit, it's hard to update the nested paging mode correctly in
    common code. So we need to update the nested paging mode in their respective
    code path.
    SVM already updates the nested paging mode on vmexit. This patch adds the 
same
    logic in VMX side.

    vmce: Allow vmce_amd_* functions to handle AMD thresolding MSRs
    
    vmce_amd_[rd|wr]msr functions can handle accesses to AMD thresholding
    registers. But due to this statement here:
    switch ( msr & (MSR_IA32_MC0_CTL | 3) )
    we are wrongly masking off top two bits which meant the register
    accesses never made it to vmce_amd_* functions.
    
    Corrected this problem by modifying the mask in this patch to allow
    AMD thresholding registers to fall to 'default' case which in turn
    allows vmce_amd_* functions to handle access to the registers.
    
    While at it, remove some clutter in the vmce_amd* functions. Retained
    current policy of returning zero for reads and ignoring writes.

    x86/MCE: Fix race condition in mctelem_reserve
    
    These lines (in mctelem_reserve)

            if (cmpxchgptr(freelp, oldhead, newhead) == oldhead) {
    
    are racy. After you read the newhead pointer it can happen that another
    flow (thread or recursive invocation) change all the list but set head
    with same value. So oldhead is the same as *freelp but you are setting
    a new head that could point to whatever element (even already used).
    
    This patch use instead a bit array and atomic bit operations.
