this looks wrong. current Kconfig statement is select ARCH_HAS_PTE_SPECIAL if !(32BIT && CPU_HAS_RIXI) so we can't use PTE_SPECIAL on 32bit _and_ CPUs with RIXI support. Why can't we use #if defined(CONFIG_ARCH_HAS_PTE_SPECIAL) here as the comment already suggests ? Thomas. -- Crap can work. Given enough thrust pigs will fly, but it's not necessarily a good idea.
