mainline inclusion from mainline-v5.11-rc1 commit c825f7885178 category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I4NGPV CVE: NA
-------------------------------------------------
This patch adds the AUX callbacks in session structure, so support AUX trace for "perf c2c" tool; make itrace memory event as default for "perf c2c", this tells the AUX trace decoder to synthesize samples and can be used for statistics.
