Subject: [PATCH 0/4] MIPS: support 47-bit userland VM space
Date: Sun, 24 Feb 2019 15:13:51 +0800 [thread overview]
Message-ID: <20190224071355.14488-1-wangxuerui@qiniu.com> (raw)
Hi,
This is my patchset to support 47-bit userland virtual memory space on
MIPS, for better application compatibility with x86_64. The
implementation is entirely shared with the previous 48-bit virtual
memory space work.
The existing mechanism is first refactored to accommodate extensions,
then 47-bit support is added as an additional case of the
now-generalized large VA support. I have been running an earlier
uncleaned version of this code for over 2 years, on Loongson 3A2000 and
3A3000, without any problem so far. This is my first patchset to
Linux/MIPS, so any review or comment is greatly appreciated!

MIPS: simplify definition of TASK_SIZE64
MIPS: refactor virtual address size selection
MIPS: define virtual address size in Kconfig
MIPS: support 47-bit userland VM space
