maillist inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I7R4EN CVE: NA Reference: https://www.spinics.net/lists/arm-kernel/msg851005.html ------------------------------------------------- Add a boolean return to arch_trigger_cpumask_backtrace() to support a use-case where a particular architecture detects at runtime if it supports NMI backtrace or it would like to fallback to default implementation using SMP cross-calls. Currently such an architecture example is arm64 supporting pseudo NMIs feature which is only available on platforms which have support for GICv3 or later version.
