This will mean an # extra stack switch when processing some interrupts, but should # significantly reduce the likelihood of stack overflow. # # It also means the softirq stack will be used for running softirqs from # other interrupts that don't use the hard irq stack, eg. timer interrupts. # # Fixes: 1b1b6a6f4cc0 ("powerpc: handle irq_enter/irq_exit in interrupt handler wrappers") # Cc:
