[PATCH] ARM: fix warning on uninitialized offset.un
    This patch fixes the following warning:

    arch/arm/mm/alignment.c: In function 'do_alignment':
    arch/arm/mm/alignment.c:327:15: warning: 'offset.un' may be used uninitialized in this function [-Wmaybe-uninitialized]
    arch/arm/mm/alignment.c:749:21: note: 'offset.un' was declared here

    The fix is to promote the initialization of offset into do_alignment().
