-Subject: arm64: run softirqs on the per-CPU IRQ stack
-
-From: Qi Zheng <zhengqi.arch@bytedance.com>
-
-[ Upstream commit 8eb858c44b98e0326bb32fca34ae671995cd73bb ]
-
-Currently arm64 supports per-CPU IRQ stack, but softirqs
-are still handled in the task context.
-
-Since any call to local_bh_enable() at any level in the task's
-call stack may trigger a softirq processing run, which could
-potentially cause a task stack overflow if the combined stack
-footprints exceed the stack's size, let's run these softirqs
-on the IRQ stack as well.
