17 * We put the hardirq and softirq counter into the preemption
18 * counter. The bitmask has the following meaning:
19 *
20 * - bits 0-7 are the preemption count (max preemption depth: 256)
21 * - bits 8-15 are the softirq count (max # of softirqs: 256)
22 * - bits 16-23 are the hardirq count (max # of hardirqs: 256)
23 *
24 * - ( bit 26 is the PREEMPT_ACTIVE flag. )
25 *
26 * PREEMPT_MASK: 0x000000ff
27 * HARDIRQ_MASK: 0x0000ff00
