Currently phys_to_virt() does not work well on 52-bits VA arm64 kernel.
One issue is contributed by phys_offset not signed.
The other is contributed by wrong page_offset.

This series fixes them so vmcore-dmesg can work on 52-bits VA kernel

Pingfan Liu (3):
  arm64: make phys_offset signed
  arm64/crashdump: unify routine to get page_offset
  arm64: read VA_BITS from kcore for 52-bits VA kernel
