Subject: Re: [PATCH v2 13/21] MIPS: traps: Give more explanations if ebase
doesn't belong to KSEG0
Hi Gregory,
kernel test robot noticed the following build warnings:
[auto build test WARNING on robh/for-next]
[also build test WARNING on lee-mfd/for-mfd-next linus/master v6.7-rc2 next-20231124]
[cannot apply to lee-mfd/for-mfd-fixes]
[If your patch is applied to the wrong git tree, kindly drop us a note.
And when submitting patch, we suggest to use '--base' as documented in
https://git-scm.com/docs/git-format-patch#_base_tree_information]
