Catalin Marinas 4f4c549feb arm64: mte: Avoid the racy walk of the vma list during core dump 
The MTE coredump code in arch/arm64/kernel/elfcore.c iterates over the
vma list without the mmap_lock held. This can race with another process
or userfaultfd concurrently modifying the vma list. Change the
for_each_mte_vma macro and its callers to instead use the vma snapshot
taken by dump_vma_snapshot() and stored in the cprm object.
