commit 97b90f9bf2e5c93e0f61c927fa2bc8a56a213faa

    xen/ppc: Ensure ELF sections' physical load addresses start at 0x0
    
    Some boot mechanisms, including the new linux file_load kexec systemcall
    used by system firmware v2.10 on RaptorCS systems will try to honor the
    physical address field of the ELF LOAD section header, which will fail
    when the address is based off of XEN_VIRT_START (0xc000000000000000).
    
    To ensure that the physical address of the LOAD section header starts at
    0x0, move x86's DECL_SECTION macro to xen.lds.h and use it to declare
    all sections.

    AMD/IOMMU: drop remaining guest-IOMMU bits too
    
    With a02174c6c885 ("amd/iommu: clean up unused guest iommu related
    functions") having removed the sole place where d->g_iommu would be set
    to non-NULL, guest_iommu_add_ppr_log() will unconditionally bail the
    latest from its 2nd if(). With it dropped, all other stuff in the file
    is unused, too. Delete iommu_guest.c altogether.
    
    Further delete struct guest{_buffer,_dev_table,_iommu{,_msi}} as well as
    struct mmio_reg for being unused with the unused g_iommu also dropped
    from struct arch_iommu.

    x86/PoD: tie together P2M update and increment of entry count
    
    When not holding the PoD lock across the entire region covering P2M
    update and stats update, the entry count - if to be incorrect at all -
    should indicate too large a value in preference to a too small one, to
    avoid functions bailing early when they find the count is zero. However,
    instead of moving the increment ahead (and adjust back upon failure),
    extend the PoD-locked region.

    xen/page_alloc: introduce page flag to stop buddy merging
    
    Add a new PGC_no_buddy_merge flag that prevents the buddy algorithm in
    free_heap_pages() from merging pages that have it set. As of now, only
    PGC_static has this feature, but future work can extend it easier than
    before.

    xen/page_alloc: introduce preserved page flags macro
    
    PGC_static and PGC_extra needs to be preserved when assigning a page.
    Define a new macro that groups those flags and use it instead of or'ing
    every time.
    
    To make preserved flags even more meaningful, they are kept also when
    switching state in mark_page_free().

    tools/xl_parse: remove message for tsc mode string
    
    Normal behavior is to be silent.  Generating a message for the preferred
    input can be mistaken for an error.  As such remove this message to match
    other conditions.
