Hi Boqun, The base tree detection is based on the whole patchset's
- subjects - touched files - TO/CC list Log shows the files and TO/CC are strongly related to powerpc, so it looks a natural choice to apply to it. Especially you put "linuxppc-...@lists.ozlabs.org" in the TO list while Peter/Ingo in the CC list -- that looks like a strong indication for powerpc. [2015-10-12 22:27:49] patched_files: ["arch/powerpc/include/asm/cmpxchg.h", "lib/atomic64_test.c", "include/linux/atomic.h", "arch/powerpc/include/asm/atomic.h"] [2015-10-12 22:27:49] bases: ["powerpc/next", "powerpc/next"] [2015-10-12 22:27:49] lists: ["linux-kernel@vger.kernel.org", "linuxppc-...@lists.ozlabs.org", "Peter Zijlstra <pet...@infradead.org>", "Ingo Molnar <mi...@kernel.org>" , "Benjamin Herrenschmidt <b...@kernel.crashing.org>", "Paul Mackerras <pau...@samba.org>", "Michael Ellerman <m...@ellerman.id.au>", "Thomas Gleixner <tglx@linutronix.d e>", "Will Deacon <will.dea...@arm.com>", "\"Paul E.
