ARM: 9429/1: ioremap: Sync PGDs for VMALLOC shadow
When sync:ing the VMALLOC area to other CPUs, make sure to also
sync the KASAN shadow memory for the VMALLOC area, so that we
don't get stale entries for the shadow memory in the top level PGD.
Since we are now copying PGDs in two instances, create a helper
function named memcpy_pgd() to do the actual copying, and
create a helper to map the addresses of VMALLOC_START and
VMALLOC_END into the corresponding shadow memory.
