SubjectRe: [PATCH 0/3] Cleanup MAY_HAVE_SPARSE_IRQ
I didn't see the patch delete:
#else /* !CONFIG_SPARSE_IRQ */
struct irq_desc irq_desc[NR_IRQS] __cacheline_aligned_in_smp = {
[0 ... NR_IRQS-1] = {
.handle_irq = handle_bad_irq,
.depth = 1,
.lock = __RAW_SPIN_LOCK_UNLOCKED(irq_desc->lock),
}
};
...

Flat irq_desc[] is simple and easy for debugging. We do want to del it?
