perf auxtrace ptt: Record whether an auxtrace mmap is needed
driver inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I7HI80 CVE: NA ---------------------------------------------------------------------- Add a flag needs_auxtrace_mmap to record whether an auxtrace mmap is needed, in preparation for correctly determining whether or not an auxtrace mmap is needed. The change was added in the mainline [1], but it was deleted when upstream openEuler for fixes build error. openEuler OLK-5.10 now has merge evsel->needs_auxtrace_mmap. Therefore, backport this modification to OpenEuler OLK-5.10.
