[PATCH 00/33] dyn_array and nr_irqs support v4

[Yinghai Lu]

Please check dyn_array support for x86
v3: split changing to nr_irqs to small patches
    fix checkpatch error
    reorder the patch sequence to make dyn_array support go at first
        so could use that with arrays other than NR_IRQS
v4: add CONFIG_HAVE_SPARSE_IRQ with list to use condensed irq_desc array
    so could use 32 init, and init more if needed.

now: x86 32bit: have CONFIG_HAVE_DYN_ARRAY
     x86 64bit: have CONFIG_HAVE_DYN_ARRAY and CONFIG_HAVE_SPARSE_IRQ

left:
a. hook irq_2_iommu to irq_desc ?
b. expand /proc/interrupts to process > nr_irqs
c. expand to use irq > nr_irqs for msi

notes: may break some arch compling...

Thanks

Yinghai Lu
