Re: [PATCH v2 0/3] Cleanup MAY_HAVE_SPARSE_IRQ

Hi Kefeng,

Most ARCHs support SPARSE_IRQ, the dynamical and statical irq
description allocation are alternative.

The last user of MAY_HAVE_SPARSE_IRQ is sh/csky, but the sh use
SPARSE_IRQ, MAY_HAVE_SPARSE_IRQ could be kill. and for csky, it
uses statical allocation by default.

So MAY_HAVE_SPARSE_IRQ seems to be useless, no need to maintain a
separate MAY_HAVE_SPARSE_IRQ config, kill it.

Also cleanup the kernel/irq/Kconfig a little.

v2:
- drop all the NR_IRQS suggested by Geert
- don' use SPARSE_IRQ for csky by default, suggested by Guo.

Kefeng Wang (3):
  sh: Cleanup about SPARSE_IRQ
  csky: Kill MAY_HAVE_SPARSE_IRQ
  genirq: Cleanup Kconfig

Thanks for the update!

Tested on SH on landisk (real) and rts7751r2d (qemu), so

P.S. Please use the same version number in all patches of the series,
     to avoid confusing tools like b4.
