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.
