From: Sumit Garg <sumit.garg@linaro.org> maillist inclusion category: feature bugzilla: 49593 CVE: NA Reference: https://www.spinics.net/lists/arm-kernel/msg851005.html ------------------------------------------------- Introduce framework to turn an IPI as NMI using pseudo NMIs. The main motivation for this feature is to have an IPI that can be leveraged to invoke NMI functions on other CPUs. And current prospective users are NMI backtrace and KGDB CPUs round-up whose support is added via future patches.
