    x86/hvm: set 'ipat' in EPT for special pages
    
    All non-MMIO ranges (i.e those not mapping real device MMIO regions) that
    map valid MFNs are normally marked MTRR_TYPE_WRBACK and 'ipat' is set. Hence
    when PV drivers running in a guest populate the BAR space of the Xen 
Platform
    PCI Device with pages such as the Shared Info page or Grant Table pages,
    accesses to these pages will be cachable.
    
    However, should IOMMU mappings be enabled be enabled for the guest then 
these
    accesses become uncachable. This has a substantial negative effect on I/O
    throughput of PV devices. Arguably PV drivers should bot be using BAR space 
to
    host the Shared Info and Grant Table pages but it is currently commonplace 
for
    them to do this and so this problem needs mitigation. Hence this patch makes
    sure the 'ipat' bit is set for any special page regardless of where in GFN
    space it is mapped.
    
    NOTE: Clearly this mitigation only applies to Intel EPT. It is not obvious
          that there is any similar mitigation possible for AMD NPT. Downstreams
          such as Citrix XenServer have been carrying a patch similar to this 
for
          several releases though.

    x86emul: replace UB shifts
    
    Displacement values can be negative, hence we shouldn't left-shift them.
    Or else we get
    
    (XEN) UBSAN: Undefined behaviour in x86_emulate/x86_emulate.c:3482:55
    (XEN) left shift of negative value -2
    
    While auditing shifts, I noticed a pair of missing parentheses, which
    also get added right here.

    x86/S3: put data segment registers into known state upon resume
    
    wakeup_32 sets %ds and %es to BOOT_DS, while leaving %fs at what
    wakeup_start did set it to, and %gs at whatever BIOS did load into it.
    All of this may end up confusing the first load_segments() to run on
    the BSP after resume, in particular allowing a non-nul selector value
    to be left in %fs.
    
    Alongside %ss, also put all other data segment registers into the same
    state that the boot and CPU bringup paths put them in.
