    x86/svm: Reduce vmentry latency
    
    Writing to the stack pointer in the middle of a line of pop operations is
    specifically recommended against by the optimisation guide, and is a 
technique
    used by Speculative Load Hardening to combat SpectreRSB.
    
    In practice, it causes all further stack-relative accesses to block until 
the
    write to the stack pointer retires, so the stack engine can get back in 
sync.
    
    Pop into any dead register to discard %rax's value without clobbering the
    stack engine.  Smaller compiled code, and runs faster.

    AMD/IOMMU: Treat guest head/tail pointers as byte offsets
    
    The MMIO registers as already formatted as byte offsets.  Start by masking 
out
    reserved bits, which fixes an implementation bug (reserved bits should be
    read-only zero, rather than preserving their previously-written value).  As 
a
    consequence, we can use the values directly, instead of masking/shifting on
    every use.
    
    Store the buffer size, rather than the number of entries, to keep the same
    units for comparison purposes.
    
    This simplifies guest_iommu_get_table_mfn() by dropping the entry_size
    parameter, and simplifies the map_domain_page() handling by being able to 
drop
    the log_base variables.

    AMD/IOMMU: Delete iommu_{get,set,clear}_bit() helpers
    
    These are obfuscations around simple bit operations, and the compiler really
    can do a better job when it can see them normally:

      guest_iommu_add_event_log                    266     251     -15
      iommu_reset_log                              274     242     -32

      guest_iommu_mmio_write                      1123    1054     -69
      Total: Before=3019344, After=3019155, chg -0.01%
    
    Drop all status register MASK/SHIFT constants, and enumerate the bits
    normally.  Rename EVENT_OVERFLOW to EVENT_LOG_OVERFLOW for consistency.  
(The
    field name in the spec is inconsistent, despite the description referring to
    an overflow of the event log.)
    
    The only semantic change is in iommu_reset_log() where 'run_bit' changes 
from
    being a bit position to being a single-bit mask.  Update some local variable
    types to be more suitable.
    
    No functional change.

    AMD/IOMMU: Move headers to be local
    
    We currently have amd-iommu-defs.h, amd-iommu-proto.h and amd-iommu.h, and 
no
    references outside of the AMD IOMMU driver.
    
    Keep iommu-defs.h as is, but merge amd-iommu.h and amd-iommu-proto.h to just
    iommu.h, and move them both into drivers/passthrough/amd/.  (While merging,
    drop the bogus #pragma pack around the *_entry structures.)
    
    Take the opportunity to trim the include lists, including x86/mm/p2m.c
    which (AFAICT) hasn't needed this include since c/s aef3f2275 "x86/mm/p2m:
    break into common, pt-implementation and pod parts" in 2011.

    xen/pvh: Fix segment selector ABI
    
    The written ABI states that %es will be set up, but libxc doesn't do so.  In
    practice, it breaks `rep movs` inside guests before they reload %es.
    
    The written ABI doesn't mention %ss, but libxc does set it up.  Having %ds
    different to %ss is obnoxous to work with, as different registers have
    different implicit segments.
    
    Modify the spec to state that %ss is set up as a flat read/write segment.
    This a) matches the Multiboot 1 spec, b) matches what is set up in practice,
    and c) is the more sane behaviour for guests to use.

    Per the ARM Generic Interrupt Controller Architecture Specification (ARM

    xen/include: public: Document the padding in struct xen_hvm_param
    
    There is an implicit padding of 2 bytes in struct xen_hvm_param between
    the field domid and index. Make it explicit by introduce a padding
    field. This can also serve as documentation.
    
    Note that I don't think we can mandate it to be zero because a guest may
    not have initialized the padding.
