Couldn't this still be implemented entirely in Kconfig, without modifying page.h? Like in the following example: [...] config VMSPLIT_1G bool "1G/3G user/kernel split" config VMSPLIT_X bool "Manual split" endchoice config PAGE_OFFSET hex range 0x40000000 0xC0000000 prompt "Memory split address (must be aligned to 4096)" if VMSPLIT_X [...] default 0x40000000 if VMSPLIT_1G default 0xC0000000 Cheers Uli - 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/
