My opinion is that SPARSE_IRQ shouldn't be user visible option, and the simple solution was to just make it hidden. It wasn't clear if this was desired or not for other arches at the time. There is a mixture of settings in powerpc defconfigs. SuperH selects it for 32-bit and leaves it user selectable for 64-bit. I'm happy to revert adding MAY_HAVE_SPARSE_IRQ and just make SPARSE_IRQ a hidden option. It really just needs the okay from SuperH folks. Rob ^ permalink raw reply [flat|nested] 2+ messages in thread

In the future I'll probably fix up the 64-bit stuff to use it too and then we'll just leave it on all the time, but it's not such a big deal if it's not visible for enabling on 64-bit at the moment given that it's probably broken there at the moment. ^ permalink raw reply [flat|nested] 2+ messages in thread
