Log message:
Make more efficient clearing interrupts on all processors at boot time.
Without this modification, because of the volatile qualifier, the
compiler does not produce four `` = 0 '' assignments, but code
equivalent to:
*(volatile uint32_t *)INT_ST_MASK3 = 0;
*(volatile uint32_t *)INT_ST_MASK2 =
*(volatile uint32_t *)INT_ST_MASK3;
*(volatile uint32_t *)INT_ST_MASK1 =
*(volatile uint32_t *)INT_ST_MASK2;
*(volatile uint32_t *)INT_ST_MASK0 =
*(volatile uint32_t *)INT_ST_MASK1;
Anders Gavare reported to Miod Vallat, and he gave me a diff.
