Re: [PATCH v7 12/14] MIPS: Share generic kernel code with other architecture

From: Jiaxun Yang
Date: Thu Feb 08 2024 - 04:38:15 EST




在 2024/2/5 15:34, Gregory CLEMENT 写道:
Some architectures might seek to utilize a significant portion of the
generic kernel code while maintaining independence from the generic
kernel due to specific peculiarities.

This patch allows for the reuse of core code, preventing unnecessary
duplication.
