Dennis Zhou 303abfdf76 percpu: fix early calls for spinlock in pcpu_stats ... From 2c06e795162cb306c9707ec51d3e1deadb37f573 Mon Sep 17 00:00:00 2001 From: Dennis Zhou <dennisz@fb.com> Date: Wed, 21 Jun 2017 10:17:09 -0700 Commit 30a5b5367e ("percpu: expose statistics about percpu memory via debugfs") introduces percpu memory statistics. pcpu_stats_chunk_alloc takes the spin lock and disables/enables irqs on creation of a chunk. Irqs are not enabled when the first chunk is initialized and thus kernels are failing to boot with kernel debugging enabled. Fixed by changing _irq to _irqsave and _irqrestore.
