I looked at applying the first 3 patches of this series to mips-next &
squashed in the relevant defconfig updates, then was looking at applying
Huacai's recent 3 patch series.
One issue is that they conflict, but beyond that it showed me that this
patch deletes kernel-entry-init.h entirely. Was that intentional? If so
it should be a separate patch & it needs an explanation.
Please could the two of you make it clear what branch & commit your
patches are based upon? Ideally it should be the current head of the
mips-next branch.
Also Jiaxun, it's really hard to see whether this patch is making any
functional changes in addition to the duplication & renaming. I think it
would be much better to split this into a few steps across multiple
commits, something like this:
1) Copy the loongson64 directory to loongson2ef, and keep the copy as-is
*except* for the removal of the loongson2ef/loongon-3 subdirectory.
Delete loongson64/fuloong-2e & loongson64/lemote-2f.
2) Now clean up the loongson64 directory by moving files up from the
loongson-3 subdirectory.
3) Now clean up code, removing #ifdef's etc that no longer make sense.
Provide the -M & -C flags to git format-patch when generating your
patches. --find-copies-harder might help with the first step, if it's
practical to run.
That way each commit will be easier to review, and issues like the
deletion of kernel-entry-init.h will be easier to spot.
For now I undid the whole thing. It's getting late in the cycle anyway,
so this will probably be v5.5 material.
Thanks,
Paul
