| * We put the hardirq and softirq counter into the preemption |
| * counter. The bitmask has the following meaning: |
| * - bits 0-7 are the preemption count (max preemption depth: 256) |
| * - bits 8-15 are the softirq count (max # of softirqs: 256) |
| * - bits 16-23 are the hardirq count (max # of hardirqs: 256) |
| * - ( bit 26 is the PREEMPT_ACTIVE flag. ) |
| * PREEMPT_MASK: 0x000000ff |
| * HARDIRQ_MASK: 0x0000ff00 |
| * SOFTIRQ_MASK: 0x00ff0000 |
