We need to attend context switch interrupts from all rings. Also, fixed writing IMR/IER and added HWSTAM at ring init time. Notice that, if added to irq_enable_mask, the context switch interrupts would be incorrectly masked out when the user interrupts are due to no users waiting on a sequence number. Therefore, this commit adds a bitmask of interrupts to be kept unmasked at all times. v2: Disable HWSTAM, as suggested by Damien (nobody listens to these interrupts, anyway). v3: Add new get/put_irq functions.
