Hi Jingyi, This patch has quite a long summary. How about instead of arm64: microbench: Use the funcions for ipi test as the general functions for gic(ipi/lpi/timer) test we use arm64: microbench: Generalize ipi test names and then in the commit message, instead of The following patches will use that. we use Later patches will use these functions for gic(ipi/lpi/timer) tests.
