Back in early 2008, 4KiB stack support was added to reduce memory consumption on workloads with lots of threads, using a separate IRQ stack per CPU to alleviate stack pressure. However the SMP code added a year and a half later didn't set up the IRQ stack when bringing up secondary CPUs, resulting in a crash when SMP is configured with 4KiB stacks, as soon as the first interrupt arrived on a secondary CPU. Fix with calls to irq_ctx_exit()/irq_ctx_exit() when bringing up/down a CPU. Signed-off-by: James Hogan <james.hogan@imgtec.com> Cc: linux-metag@vger.kernel.org |
