[PATCH v3 0/2] arm64: mm: Enhance Virtual kernel memory layout

[Kefeng Wang]

This is a micro enhance for Virtual kernel memory layout. Show bss info,
and make each line with single pr_cont().

With this patchset,

Changes since v2:
- Add tested/ack by James Morse.
- Remove restrictive printing, keep the same as mm/dump.c.

Changes since v1:
- Drop vector info and spilt the patch, suggested by James Morse.
