This week I succeeded in building a stripped-down kernel without mlong-calls (in Gentoo), but was unable to get anything to link without mlong-calls when CONFIG_PARISC_PAGE_SIZE_16KB=y. With mlong-calls, I couldn't get a 16K page-size kernel to boot either. Is this a configuration anyone uses or tests? 16K pages are supposed to give better performance, so it'd be good if they worked.
