Regressions :-(

Tests which did not succeed and are blocking,
including tests which could not be run:
 test-armhf-armhf-xl-xsm     15 guest-start/debian.repeat fail REGR. vs. 106844
 test-armhf-armhf-libvirt      6 xen-boot                 fail REGR. vs. 106844
 test-armhf-armhf-xl-vhd     14 guest-start/debian.repeat fail REGR. vs. 106844

    xen/arm: alternative: Register re-mapped Xen area as a temporary virtual

    While I was using the alternative patching in the SErrors patch series [1].
    I used a branch instruction as alternative instruction.
    
            ALTERNATIVE("nop",
                        "b skip_check",
                        SKIP_CHECK_PENDING_VSERROR)

    (XEN) ****************************************
    (XEN) Panic on CPU 0:
    (XEN) Xen BUG at alternative.c:61
    (XEN) ****************************************
    
    This panic was triggered by the BUG(); in branch_insn_requires_update.
    That's because in this case the alternative patching needs to update the
    offset of the branch instruction. But the new target address of the branch
    instruction could not pass the check of is_active_kernel_text();
    
    The reason is that: When Xen is booting, it will call apply_alternatives_all
    to do patching with alternative tables. In this progress, we should update
    the offset of branch instructions if required. This means we should modify
    the Xen text section. But Xen text section is marked as read-only and we
    configure the hardware to not allow a region to be writable and executable 
at
    the same time. So we re-map Xen in a temporary area for writing. In this 
case,
    the calculation of the new target address of the branch instruction is based
    on this re-mapped area. The new target address will point to a value in the
    re-mapped area. But we haven't registered this area as an active kernel 
text.
    So the check of is_active_kernel_text will always return false.
    
    We have to register the re-mapped Xen area as a virtual region temporarily 
to
    solve this problem.
