Subject: Re: [PATCH v4 2/5] Replace generic memcpy and memset by IO memcpy
functions
Hi Julian,
kernel test robot noticed the following build errors:
[auto build test ERROR on akpm-mm/mm-nonmm-unstable]
[also build test ERROR on arm64/for-next/core soc/for-next linus/master v6.11 next-20240924]
[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
