What do you want to do?
local_irq_save()/local_irq_restore() temporarily disable the interrupt
processing of the current cpu. Note that other cpus in the system
continue to handle interrupts.
disable_irq(x) disables the interrupt processing for the interrupt line x.
For example, my network drivers use disable_irq() to synchronize
interrupt processing and error recovery.
