Subject: [PATCH v3 0/2] arm64: mm: Enhance Virtual kernel memory layout
Date: Thu, 12 May 2016 20:16:25 +0800	[thread overview]
Message-ID: <1463055387-19289-1-git-send-email-wangkefeng.wang@huawei.com> (raw)
In-Reply-To: <1460948988-7477-1-git-send-email-wangkefeng.wang@huawei.com>

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.

Kefeng Wang (2):
  arm64: mm: make pr_cont() per line in Virtual kernel memory layout
  arm64: mm: Show bss segment in kernel memory layout
