That's why I added what seems to be needed for s390. For CONFIG_PTSHARE and CONFIG_PTSHARE_PTE it's just a slightly modified Kconfig file. For CONFIG_PTSHARE_PMD it involves adding a few more pud_* defines to asm-generic/4level-fixup.h. Seems to work with the pmd/pud_clear changes as far as I can tell. Just tested this out of curiousity :) Thanks, Heiko - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
