This will actually stop being the same soon with GB pages which are only supported on 64bit. > + > +#ifdef CONFIG_X86_64 > +#define THREAD_ORDER 1 > +#define THREAD_SIZE (PAGE_SIZE << THREAD_ORDER) > +#define CURRENT_MASK (~(THREAD_SIZE-1)) > + > +#define EXCEPTION_STACK_ORDER 0 > +#define EXCEPTION_STKSZ (PAGE_SIZE << EXCEPTION_STACK_ORDER) > + > +#define DEBUG_STACK_ORDER (EXCEPTION_STACK_ORDER + 1) > +#define DEBUG_STKSZ (PAGE_SIZE << DEBUG_STACK_ORDER) > + > +#define IRQSTACK_ORDER 2 > +#define IRQSTACKSIZE (PAGE_SIZE << IRQSTACK_ORDER) This all seems hardly 64bit specific (except for THREAD_ORDER but you can probably handle that in Kconfig or just get rid of it for 32bit) > +#define __PHYSICAL_START CONFIG_PHYSICAL_START Also not 64bit specific > +#ifdef CONFIG_X86_PAE > +#define __PHYSICAL_MASK_SHIFT 36 I originally added the PHYSICAL_MASK stuff to deal with masking off NX, but I must admit it wasn't the best idea I ever had. It would be probably better to just get rid of it and always mask off the high reserved flags bit explicitely. If you make that 0 then there should be no special case for PAE. -Andi -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
