MIPS: Netlogic: SMP fixes for XLR/XLS platform code. (39263eeb) · Commits · 戴 / test

Fix few issues in the Netlogic code: - Use handle_percpu_irq to handle per-cpu interrupts - Remove unused function nlm_common_ipi_handler() - Call scheduler_ipi() on SMP_RESCHEDULE_YOURSELF - Enable interrupts in nlm_smp_finish() Signed-off-by:
