    parisc/mm: Ensure IRQs are off in switch_mm() · 649aa242
    Helge Deller authored
    This is because of commit f98db601 ("sched/core: Add switch_mm_irqs_off()
    and use it in the scheduler") in which switch_mm_irqs_off() is called by the
    scheduler, vs switch_mm() which is used by use_mm().
    
    This patch lets the parisc code mirror the x86 and powerpc code, ie. it
    disables interrupts in switch_mm(), and optimises the scheduler case by
    defining switch_mm_irqs_off().
