Zoned Block Devices (ZBDs) devide the LBA space to block regions called zones
that are larger than the LBA size. It can only allow sequential writes, which
reduces write amplification in SSD, leading to higher throughput and increased
capacity. More details about ZBDs can be found at:

Now that cs->interrupt_request indicates if there is any unmasked
interrupt, checking if the CPU has work to do can be simplified to a
single check that works for all CPU models.

This new method will check if any pending interrupt was unmasked and
then call cpu_interrupt/cpu_reset_interrupt accordingly. Code that
raises/lowers or masks/unmasks interrupts should call this method to
keep CPU_INTERRUPT_HARD coherent with env->pending_interrupts.

The new method is based on cpu_has_work_POWER7 and

This enum defines the bit positions in env->pending_interrupts for each
interrupt. However, except for the comparison in kvmppc_set_interrupt,
the values are always used as (1 << PPC_INTERRUPT_*). Define them
directly like that to save some clutter. No functional change intended.
