commit ffda547469694ff22b6c8d0bc23436c9b4ce84ec

    xen/arm: p2m: Release the p2m lock before undoing the mappings
    
    Since commit 4b25423a "arch/arm: unmap partially-mapped memory regions",
    Xen has been undoing the P2M mappings when an error occurred during
    insertion or memory allocation.
    
    This is done by calling recursively apply_p2m_changes, however the
    second call is done with the p2m lock taken which will result in a
    deadlock for the current processor.
    
    The p2m lock is here to protect 2 threads modifying concurrently the
    page tables. However, it does not guarantee the ordering of the
    changes. I.e if 2 threads request change on regions that overlaps,
    then the result is undefined.
    
    Therefore it is fine to move the recursive call to undo the changes
    after the lock is released.

commit d4d37391c4f2a1fe522de51f2a86c325f11ba0c3
Author: Julien Grall <julien.grall@xxxxxxx>

    xen/arm: p2m: apply_p2m_changes: Do not undo more than necessary
    
    Since commit 4b25423a "arch/arm: unmap partially-mapped memory regions",
    Xen has been undoing the P2M mappings when an error occurred during
    insertion or memory allocation.
    
    The function apply_p2m_changes can work with region not-aligned to a
    block size (2MB, 1G) or page size (4K). The mapping will be done by
    splitting the region in a set of regions aligned to the size supported
    by the page table.
    
    The mapping of a region could fail when it is not possible to allocate
    memory for an intermediate table (i.e a new or when shattering a block).
    
    When the mapping is undone, the end of the region is computed using the
    base address of the current region and the size of the failing level.
    However the failing level may not be the leaf one, therefore unrelated
    entries will be removed.
    
    Fix it by removing the mapping from the start address up to the last
    region that has been successfully mapped.
