Sure it can work. The ABI specifies limits on such things. Probably the most appropriate size is the one specified for alignment of ELF sections.
If I remember right, it's 64 K for the PowerPC ABI. This allows for 64 K pages, even though many chips offer 4 K pages. - 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/
