Hi,

This is the v2 of:
https://www.linux-mips.org/archives/linux-mips/2018-09/msg00641.html

Changelog:

v1 -> v2:
- Rebased on v4.19-rc5
- Addressed Paul's comments:
  https://www.linux-mips.org/archives/linux-mips/2018-09/msg00735.html


The patch is also available at:
https://github.com/yashac3/linux-rtl8186/commits/unaligned_load_store_on_4_19


Please review.

This is a prerequisite patch required for adding Lexra CPU [1] support in
arch/mips.
It does not add any Lexra CPU support yet, but it is required for such future
support.

The patch is written on top of v4.19-rc5.

Background:
I'm currently working on porting Linux/MIPS to run on the Realtek RTL8186 SoC [1],
which has Lexra LX5280 CPU [2].

The complete Lexra+RTL8186 support is still WIP [3] so I'm not sending that
for review right now.

Thanks,
Yasha
