    xen/arm: Correct the p2m pool size calculations
    
    Allocating or freeing p2m pages doesn't alter the size of the mempool; only
    the split between free and used pages.
    
    Right now, the hypercalls operate on the free subset of the pool, meaning 
that
    XEN_DOMCTL_get_paging_mempool_size varies with time as the guest shuffles 
its
    physmap, and XEN_DOMCTL_set_paging_mempool_size ignores the used subset of 
the
    pool and lets the guest grow unbounded.
    
    This fixes test-pagign-mempool on ARM so that the behaviour matches x86.
    
    This is part of XSA-409 / CVE-2022-33747.

    xen/arm, libxl: Revert XEN_DOMCTL_shadow_op; use p2m mempool hypercalls
    
    This reverts most of commit cf2a68d2ffbc3ce95e01449d46180bddb10d24a0, and 
bits
    of cbea5a1149ca7fd4b7cdbfa3ec2e4f109b601ff7.
    
    First of all, with ARM borrowing x86's implementation, the logic to set the
    pool size should have been common, not duplicated.  Introduce
    libxl__domain_set_paging_mempool_size() as a shared implementation, and use 
it
    from the ARM and x86 paths.  It is left as an exercise to the reader to 
judge
    how libxl/xl can reasonably function without the ability to query the pool
    size...
    
    Remove ARM's p2m_domctl() infrastructure now the functioanlity has been
    replaced with a working and unit tested interface.
    
    This is part of XSA-409 / CVE-2022-33747.

    xen: Introduce non-broken hypercalls for the paging mempool size
    
    The existing XEN_DOMCTL_SHADOW_OP_{GET,SET}_ALLOCATION have problems:
    
     * All set_allocation() flavours have an overflow-before-widen bug when
       calculating "sc->mb << (20 - PAGE_SHIFT)".
     * All flavours have a granularity of 1M.  This was tolerable when the size 
of
       the pool could only be set at the same granularity, but is broken now 
that
       ARM has a 16-page stopgap allocation in use.
     * All get_allocation() flavours round up, and in particular turn 0 into 1,
       meaning the get op returns junk before a successful set op.
     * The x86 flavours reject the hypercalls before the VM has vCPUs allocated,
       despite the pool size being a domain property.
     * Even the hypercall names are long-obsolete.
    
    Implement a better interface, which can be first used to unit test the
    behaviour, and subsequently correct a broken implementation.  The old
    interface will be retired in due course.
    
    The unit of bytes (as opposed pages) is a deliberate API/ABI improvement to
    more easily support multiple page granularities.
    
    This is part of XSA-409 / CVE-2022-33747.

    x86/hvm: Revert per-domain APIC acceleration support
    
    I was really hoping to avoid this, but its now too late in the 4.17 freeze 
and
    we still don't have working fixes.
    
    The in-Xen calculations for assistance capabilities are buggy.  For the
    avoidance of doubt, the original intention was to be able to control every
    aspect of a APIC acceleration so we could comprehensively test Xen's 
support,
    as it has proved to be buggy time and time again.
    
    Even after a protracted discussion on what the new API ought to mean, 
attempts
    to apply it to the existing logic have been unsuccessful, proving that the
    API/ABI is too complicated for most people to reason about.
    
    This reverts most of:
      2ce11ce249a3981bac50914c6a90f681ad7a4222
      6b2b9b3405092c3ad38d7342988a584b8efa674c
    
    leaving in place the non-APIC specific changes (minimal as they are).
    
    This takes us back to the behaviour of Xen 4.16 where APIC acceleration is
    configured on a per system basis.
    
    This work will be revisted in due course.
