From 6fdb0f410bb026ade092039a6c2655a53323c996 Mon Sep 17 00:00:00 2001 From: Nicholas Piggin Date: Sat, 30 Jan 2021 23:08:43 +1000 Subject: [PATCH] powerpc/64: add context tracking to asynchronous interrupts Previously context tracking was not done for asynchronous interrupts, (those that run in interrupt context), and if those would cause a reschedule when they exit, then scheduling functions (schedule_user, preempt_schedule_irq) call exception_enter/exit to fix this up and exit user context. This is a hack we would like to get away from, so do context tracking for asynchronous interrupts too.
