Sure - we will go with that.

./linux-2.6.x/include/asm-parisc/system.h

/* interrupt control */
#define local_save_flags(x) __asm__ __volatile__("ssm 0, %0" : "=r" (x)
: : "memory")
#define local_irq_disable() __asm__ __volatile__("rsm %0,%%r0\n" : :
"i" (PSW_I) : "memory" )
#define local_irq_enable() __asm__ __volatile__("ssm %0,%%r0\n" : :
"i" (PSW_I) : "memory" )
