Subject: [PATCH v2 0/3] arm64: mm: Enhance Virtual kernel memory layout
Date: Mon, 18 Apr 2016 11:09:45 +0800 [thread overview]
Message-ID: <1460948988-7477-1-git-send-email-wangkefeng.wang@huawei.com> (raw)
In-Reply-To: <1460533772-13314-1-git-send-email-wangkefeng.wang@huawei.com>
This is a micro enhance for Virtual kernel memory layout. Show bss info,
add restriction for modules and PCI I/O printing, and make each line with
single pr_cont().
With this patchset,

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