commit 6bec713f871f21c6254a5783c1e39867ea828256
Author: Jan Beulich <jbeulich@xxxxxxxx>

    include/compat: produce stubs for headers not otherwise generated
    
    Public headers can include other public headers. Such interdependencies
    are retained in their compat counterparts. Since some compat headers are
    generated only in certain configurations, the referenced headers still
    need to exist. The lack thereof was observed with hvm/hvm_op.h needing
    trace.h, where generation of the latter depends on TRACEBUFFER=y. Make
    empty stubs in such cases (as generating the extra headers is relatively
    slow and hence better to avoid). Changes to .config and incrementally
    (re-)building is covered by the respective .*.cmd then no longer
    matching the command to be used, resulting in the necessary re-creation
    of the (possibly stub) header.

    x86/shadow: call sh_detach_old_tables() directly
    
    There's nothing really mode specific in this function anymore (the
    varying number of valid entries in v->arch.paging.shadow.shadow_table[]
    is dealt with fine by the zero check, and we have other similar cases of
    iterating through the full array in common.c), and hence there's neither
    a need to have multiple instances of it, nor does it need calling
    through a function pointer.
    
    While moving the function drop a non-conforming and not very useful
    (anymore) comment.

    x86/shadow: reduce effort of hash calculation
    
    The "n" input is a GFN/MFN value and hence bounded by the physical
    address bits in use on a system. The hash quality won't improve by also
    including the upper always-zero bits in the calculation. To keep things
    as compile-time-constant as they were before, use PADDR_BITS (not
    paddr_bits) for loop bounding. This reduces loop iterations from 8 to 5.
    
    While there also drop the unnecessary conversion to an array of unsigned
    char, moving the value off the stack altogether (at least with
    optimization enabled).

    x86/shadow: drop a few uses of mfn_valid()
    
    v->arch.paging.shadow.shadow_table[], v->arch.paging.shadow.oos[],
    v->arch.paging.shadow.oos_{snapshot[],fixup[].smfn[]} as well as the
    hash table are all only ever written with valid MFNs or INVALID_MFN.
    Avoid the somewhat expensive mfn_valid() when checking MFNs coming from
    these arrays.

Author: Xenia Ragiadakou <burzalodowa@xxxxxxxxx>
Date:   Thu Jan 12 11:09:16 2023 +0100

    x86/iommu: introduce AMD-Vi and Intel VT-d Kconfig options
    
    Introduce two new Kconfig options, AMD_IOMMU and INTEL_IOMMU, to allow code
    specific to each IOMMU technology to be separated and, when not required,
    stripped. AMD_IOMMU will be used to enable IOMMU support for platforms that
    implement the AMD I/O Virtualization Technology. INTEL_IOMMU will be used to
    enable IOMMU support for platforms that implement the Intel Virtualization
    Technology for Directed I/O.
    
    Since, at this point, disabling any of them would cause Xen to not compile,
    the options are not visible to the user and are enabled by default if X86.
