commit 910b590601970440bdb135ed83fe28d8a755173e

    xen/arm: Save/restore GICH_VMCR on domain context switch
    
    GICH_VMCR register contains alias to important bits of GICV interface such 
as:
        - priority mask of the CPU
        - EOImode
        - ...
    
    We were safe because Linux guest always use the same value for this bits.
    When new guests will handle priority or change EOI mode, VCPU interrupt
    management will be in a wrong state.

commit 4959e0eacf56456a4b16d59e98cec58f7c2d66be
Author: Julien Grall <julien.grall@xxxxxxxxxx>

    xen/arm: Correctly handle non-page aligned pointer in raw_copy_from_guest
    
    The current implementation of raw_copy_guest helper may lead to data 
corruption
    and sometimes Xen crash when the guest virtual address is not aligned to
    PAGE_SIZE.
    
    When the total length is higher than a page, the length to read is badly
    compute with
        min(len, (unsigned)(PAGE_SIZE - offset))
    
    As the offset is only computed one time per function, if the start address 
was
    not aligned to PAGE_SIZE, we can end up in same iteration:
        - to read accross page boundary => xen crash
        - read the previous page => data corruption
    
    This issue can be resolved by setting offset to 0 at the end of the first
    iteration. Indeed, after it, the virtual guest address is always aligned
    to PAGE_SIZE.
