    xen/arm: p2m: Fix hypercall preemption when domain is relinquish memory 
mapping
    
    The commit 84f29a9 "xen/arm: Add relinquish_p2m_mapping to remove reference 
on
    every mapped page" doesn't save correctly the next gfn when the hypercall
    is preempted.
    
    Instead of storing the next gfn, it store the next mfn. Fix it by using
    'addr' instead of 'maddr'.

    xen/arm: Set foreign page type to p2m_map_foreign
    
    Xen needs to know that the current page belongs to another domain. Also take
    a reference to this page.
    
    The current process to add a foreign page is:
       1) get the page from the foreign p2m
       2) take a reference on the page with the foreign domain in parameters
       3) add the page to the current domain p2m
    
    If the foreign domain drops the page:
        - before 2), get_page will return NULL because the page doesn't
        belong anymore to the domain
        - after 2), the current domain already have a reference. Write will
        occur to an old page which is not yet released. It can corrupt the 
foreign
        domain.

    xen/arm: Add relinquish_p2m_mapping to remove reference on every mapped page
    
    This function will be called when the domain relinquishes its memory.
    It removes refcount on every mapped page to a valid MFN.
    
    Currently, Xen doesn't take reference on every new mapping but only for 
foreign
    mapping. Restrict the function only on foreign mapping.

    xen/arm: Store p2m type in each page of the guest
    
    Use the field 'avail' to store the type of the page. Rename it to 'type' for
    convenience.
    The information stored in this field will be retrieved in a future patch to
    change the behaviour when the page is removed.
    
    Also introduce guest_physmap_add_entry to map and set a specific p2m type 
for
    a page.

    xen/arm: Implement p2m_type_t as an enum
    
    Until now, Xen doesn't know the type of the page (ram, foreign page, 
mmio,...).
    Introduce p2m_type_t with basic types:
        - p2m_invalid: Nothing is mapped here
        - p2m_ram_rw: Normal read/write guest RAM
        - p2m_ram_ro: Read-only guest RAM
        - p2m_mmio_direct: Read/write mapping of device memory
        - p2m_map_foreign: RAM page from foreign guest
        - p2m_grant_map_rw: Read/write grant mapping
        - p2m_grant_map_ro: Read-only grant mapping

    xen/arm: move mfn_to_p2m_entry in arch/arm/p2m.c
    
    The function mfn_to_p2m_entry will be extended in a following patch to 
handle
    p2m_type_t. It will break compilation because p2m_type_t is not defined
    (interdependence between includes).
    It's easier to move the function in arch/arm/p2m.c and it's not harmful as 
the
    function is only used in this file.

    xen: arm: process XENMEM_add_to_physmap_range forwards not backwards.
    
    Jan points out that processing the list backwards is rather counter 
intuitive
    and that the effect of the hypercall can differ between forwards and 
backwards
    processing (e.g. in the presence of duplicate idx or gpfn, which would be
    unusual but as Jan says, users are a creative bunch)
