Hi All, I would like to put up for discussion a merge of the m68knommu and m68k arch branches. Attached is a script and patch that does a kind of brute force simplistic merge of the directories and files. (Thanks to Stephen King <sfking@xxxxxxxxx> for the initial version of this script, and to Sam Ravnborg for the m68k includes merge script this was based on). Nothing outside of the arch/m68k and arch/m68knommu directories is touched, and in the end there is no more arch/m68knommu. To apply you simply run the script from the top of a current kernel git tree (I used 2.6.38-rc5 for testing) and then apply the patch.
The initial version of said script was created by Arnd IIRC.
Thoughts?
When we merged x86, sh and sparc in the past this has in all cases helped sharing coe between the 32 and 64 bit variants. There has in all cases been some code-chrunch in the beginning, but the result has been good. What as often caused some troubles has been how to configure the individual architectures. We have for eaxample: make ARCH=x86, make ARCH=i386, make ARCH=x86_64 today. Likewise for sparc we have: make ARCH=sparc, make ARCH=sparc32, make ARCH=sparc64 So you need to consider how to deal with this for m68k. Maybe MMU is just an option so you only have ARCH=m68k in the end? You do not touch upon the maintenance of the merged trees. Today there is different maintainers for the two archs. To have a transparent flow the better solution is likely that all m68k* patches go via one of your trees so we do not have two trees that deal with m68k upstream. I assume we will sort it all out naturally and I hope that we soon will have m68k and m68knommu merged!
